Upgrades and Accessories to Expand Your Camera’s Creative Potential
If you bought your camera with a lens, then you have everything you need to begin shooting with your D750. I took great care to ensure that almost all of the techniques covered in the book are not beyond your basic camera setup. That being said, there are some accessories that are essential for certain types of photography. Other accessories aren’t necessarily essential, but they will improve the look of your images.
Let’s take a look at some items that I believe are must-have accessories for your photography.
Filters
You should have several filters in your camera bag. Each one serves a unique purpose. Some say that digital imaging programs such as Adobe Photoshop can duplicate the effects that the filters offer. This may be true, but I would rather screw on a filter than spend countless hours trying to replicate an effect on my computer. Here’s another benefit to using a filter: lens protection.
Skylight
Probably the cheapest yet best investment you can make for your camera is buying a skylight filter. This filter is used more for its protective effects than for any visual boost. At one point in time, the skylight, UV, and haze filters were used to filter out UV light in order to add sharpness to distant subjects, correct a minute bluish color cast, and reduce the effects of haze in a film image. A digital camera offers the benefit of having filters that are built into the camera in front of the image sensor to eliminate the effects of haze and infrared light. Therefore, most of the visual benefits of using a skylight filter are not evident. So why, if there is no real visual difference, should you use a skylight filter? Because what they do offer is protection for your valuable lens for a relatively low price.
A 28–300mm Nikon VR lens will cost you about $970. A 77mm HOYA Skylight 1B filter costs around $35. As someone who often either forgets or loses lens caps, it’s reassuring to me that a $35 filter protects the precious glass on the front of my lens without degrading the quality of my image. If it does get scratched, I just unscrew it and buy another. That beats the heck out of $970 or thereabouts to replace or repair a scratched front lens element.
Polarizing
This one ranks right up there at the top of the list of must-own photography accessories. You won’t find a self-respecting landscape photographer who doesn’t have at least one polarizer in his or her camera bag (Figure 11.1).
Light travels in straight lines, but the problem is that all those lines are moving in different directions. When they enter the camera lens, they are scattering about, creating color casts and other effects. The polarizer controls how light waves are allowed to enter the camera, letting only certain ones pass through. So what does that mean for you? With a polarizing filter, blue skies will appear darker, vegetation color will be more accurate, colors will look more saturated, haze will be reduced, and images can look sharper (Figures 11.2 and 11.3). Not bad for a little piece of glass.
Figure 11.2 Without using the polarizing filter, the scene looks a little low on contrast and has a blue color cast from the sky.
Figure 11.3 After adding a polarizer, the colors are much more accurate and the color cast is now gone.
Most polarizers are circular and allow you to rotate the polarizing element to control the amount of polarization that you need. As the filter is rotated, different light waves will be allowed to pass through, such as a reflection on a body of water (Figure 11.4). Turn the filter a little and the light waves from the reflection are blocked, making the reflection disappear (Figure 11.5). Another benefit of the filter is that it is fairly dark so, when used in bright lighting conditions, it can act as a neutral density filter (you’ll learn more in the next section), allowing you to use larger apertures or slower shutter speeds. The average polarizing filter requires an increase in exposure of about one and a half stops. This won’t be an issue for you since you will be using the camera meter, which is already looking through the filter to calculate exposure settings. You should consider it, though, if your intention is to shoot with a fast shutter speed or use a small aperture for increased depth of field.
Figure 11.4 Before adding a polarizer, the sky is reflected in the water.
Figure 11.5 After adding a polarizer, you can see through the surface of the water.
Neutral density (ND)
Sometimes there is just too much light falling on your scene to use the camera settings that you want. Most often this is the case when you want to use a slow shutter speed but your lens is already stopped down to its smallest aperture, leaving you with a shutter speed that’s faster than you want.
A classic example of this is shooting a waterfall in bright sunlight. To get the silky look to the water, the shutter speed needs to be about 1/15 of a second or slower. The problem is that a proper exposure for bright sunlight is f/16 at 1/100 of a second with the camera set to ISO 100 (this comes from the Sunny 16 rule). If my lens has a minimum aperture of f/22, the slowest shutter speed I will be able to use is 1/50.
The way around this problem is to use a neutral density (ND) filter to make the outside world appear to be a little darker. Think of it as sunglasses for your camera. ND filters come in different strengths, which are labeled as 0.3, 0.6, and 0.9 (though there are stronger filters available too, such as the 10-stop ND filter from Lee). They represent a one-stop difference in exposure per each 0.3 increment. If you need to turn daylight into dark, the 0.9 ND filter will give you an extra three stops of exposure (Figure 11.6). This means that, in my earlier example, I could get an exposure of f/16 at about 1/10 of a second. This would be an ideal exposure for getting silky smooth water in motion (Figure 11.7).
Figure 11.7 A 0.9 ND filter allowed me to use a long shutter speed in daylight to smooth out the ripples in a rushing river.

Graduated ND
Another favorite of the landscape photographer, the graduated ND has the benefit of the standard ND filter but graduates to a clear portion (Figure 11.8). This allows you to darken just the upper or lower portion of your scene while leaving the other part unaffected. This filter is most commonly used to darken skies that are too bright (Figure 11.9) without affecting the ground area (Figure 11.10). If a regular ND is used, the entire area will get darker, so there is no visual change in the image as far as the brightness ratio between the sky and the ground is concerned.
Figure 11.8 Graduated filters come in different strengths and transitions, from soft to hard, and allow you to expose for the darker areas (ground) without blowing out the brighter regions (sky).
Figure 11.9 Even though the sky is filled with clouds it is much brighter than the ground, and that makes for a tricky exposure situation.
Figure 11.10 With a 0.9 ND graduated neutral density filter placed over the sky, I was able to expose for the foreground and retain detail in the brighter mountains and sky.
You can purchase the graduated ND as a screw-on filter, but most photographers prefer to use the larger 4x6” version, which allows them to control exactly where the filter transitions from dark to transparent. There are many different options when looking for graduated ND filters, such as the density factor (number of stops) and how gradual the transition is from dark to clear.
Tripods
If you buy only one accessory for your photography, do yourself a favor and make it a tripod. In general, any tripod is going to be better than no tripod at all. A tripod makes your photos sharper and lets you shoot in any lighting condition. There are more choices in tripods than there are in DSLRs. So how do you go about choosing the right one for you? The main considerations are weight, height, and head.
The weight of your tripod will probably determine whether or not you will actually carry it along with you farther than the parking lot. Many different types of materials are used in tripods today. The lightest is carbon fiber, which is probably the most expensive as well. More than likely, you should consider an aluminum tripod that is sturdy and has a weight rating that is suitable for your camera as well as your lenses.
Make sure that the tripod extends to a height that is tall enough to allow you to shoot from a comfortable standing position. Nothing ruins a good shoot like a sore back. Taller tripods need to be sturdier to maintain a rigid base for your camera. You will also want to consider how low the tripod can go. If you want to do macro work of low-level subjects such as flowers, you will need to lower the tripod fairly close to the ground. Many new tripods have leg supports that allow you to spread the legs very wide and get the camera low to the ground.
The other determining factor when purchasing a tripod will be the type of head that it employs to secure the camera to the legs. There are two basic types of tripod heads: ball and pan. Ball heads use a simple ball joint that allows you to freely position the camera in any upright position and then clamp it down securely. This type of head is flexible and quick to use, but it can sometimes be difficult to switch between portrait and landscape orientations. They also tend to be slightly more expensive as well.
Pan heads employ a swivel and usually two hinged joints that allow the camera to pan left and right, move up and down, and adjust the position along the horizontal axis. Handles are typically employed to allow movement of the camera and lock down the position. The pan head is by and large the most popular tripod head style on the market. If you plan on shooting a lot of video with your D750, you might want to consider the pan head style since it will deliver more functionality for your videography, specifically panning from side to side.
If you really want to make your tripod shooting move faster, consider buying a tripod that utilizes a quick-release head. There are many styles of quick-release brackets; most use a small plate that screws into the bottom of the camera and then quickly locks into and releases from the tripod head.
The other thing to consider when purchasing a tripod is the leg locking system. Whether it is a lever-lock, locking rings, or some other system, make sure that you test it thoroughly to see how easy it is to lock and unlock the leg positions. Also check to see how smoothly the legs retract and extend. Avoid legs that stick because they will probably only get stickier over time.
There are many different brands of tripod to choose from, but I suggest sticking to Gitzo (www.gitzo.com), Giottos (www.giottos.com), Manfrotto (www.manfrotto.com), and Really Right Stuff (www.reallyrightstuff.com) for rock-solid tripods and tripod accessories.
Remote or Cable Release
When shooting long exposures, you can use the self-timer to activate the camera or you can get yourself a wireless remote or a cable release. My favorite option is the wireless ML-L3 (Figure 11.11), which uses an infrared beam (just like your TV remote) to fire the shutter from a distance of up to around 16 feet. Another option is the MC-DC2 remote release cord (Figure 11.12), which is an electronic release that attaches to the camera via the remote port and lets you trip the shutter. A remote release is the preferred tool of choice when shooting with the camera set to Bulb (see Chapter 9). The idea of the release is that it allows shutter activation without having to place your hands on the camera. This is the best way to ensure that your images will not be influenced by self-induced camera shake. The ML-L3 sells for around $20, and the MC-DC2 sells for around $35, and both will work with not only the D750 but also several other Nikon DSLR models on the market. A remote also comes in handy for shooting macro work, where the tiniest vibration can affect the sharpness of your image.
Figure 11.11 The Nikon ML-L3 wireless remote lets you activate the shutter without touching the camera.
To take advantage of the built-in Wi-Fi functionality, you’ll need to download and install the free Wireless Mobile Utility (WMU) application for Android and iOS to your mobile device. Then you can enable the Wi-Fi feature in the D750 Setup menu and connect the camera to your device via Wi-Fi. Once it’s connected, you can remotely trigger the camera shutter (Figure 11.13) from your mobile device and download the photos right to your mobile device for easy sharing.
Macro Photography Accessories
Extension tubes
Extension tubes are like spacers between your lens and your camera. The tubes are typically hollow, and their sole purpose is to move the rear of the lens farther away from the camera body.
A lens can only get so close to a subject and still be able to achieve a sharp focus. This is because as the subject gets closer, the focal point for the lens moves back to a point where it is behind the image sensor. Using an extension tube lets you move that focal point forward by placing the rear of the lens a little farther away from the camera sensor, thus letting you get the lens closer to the subject and enlarging it in your picture.
The tubes come in varying sizes, which are typically measured in millimeters. The more common sizes are 12mm, 20mm, and 36mm. The longer the tube, the greater the magnification factor (up to 1:1). The tubes are best used with lenses that are 35mm in focal length and longer. A wide-angle lens will have such a short focusing distance that you will be right on top of your subject. Nikon manufactures several extension tubes, or you can buy them from third-party manufacturers. Prices vary, but you will pay more for tubes that utilize optics in their design. You can also purchase sets of tubes with varying lengths that can be used individually or stacked together for greater magnification.
Close-up filters
Another great way to jump into macro work is by purchasing a close-up filter (Figures 11.14 and 11.15). Close-up filters also come in varying magnifications but tend to be a little more expensive than extension tubes. This is because they are usually made of high-quality glass that works in concert with the lens. The filters and lenses can have some advantages over tubes, too. Because they screw onto the front of your lens, they don’t interfere with any of the communication functions between the lens and camera body. They also result in less loss of light, so exposures can be slightly shorter than when you’re using extension tubes. They do, however, work similarly to tubes in that they allow you to shorten the minimum focus distance of your lens so that you can move closer to your subject, thereby increasing the size of the subject on your sensor. Close-up lenses usually come in magnification factors like +1, +2, +3, +4, and +5. They can also be stacked, strongest to weakest, to increase the magnification factor.
Figure 11.14 The Canon 500 D close-up filter. Yes, it’s made by Canon, but since it is a screw-on piece of glass it works with any camera model.
Figure 11.15 I used the Canon 500 D close-up filter on a Nikon 70–200 lens with a 2x teleconverter to capture this frosty close-up.
The other difference is that they are usually screw-threaded onto your lens, which means that you have to purchase a specific thread diameter. So if your favorite lens has a 68mm filter thread, that is the size you would use for the close-up filter. The big downside is that if you want to use different lenses that have different thread sizes, you will have to buy multiple filters. One solution is to work with a zoom lens so that you can have a range of focal lengths to use with just one filter. Also, just as with most glass filters, the larger the diameter, the higher the price. Another solution to this problem is to use a step-up ring, which allows you to thread a large filter to a smaller lens. I purchase all my filters at 77mm and then use step-up rings to attach them to smaller-diameter lenses.
Hot-Shoe Flashes
Earlier in the book I covered the built-in flash and what you can accomplish with it. Now that we have covered that, let me say that you really, really need to get yourself a hot-shoe mounted Speedlight flash if you want to take better flash images. For one thing, the external flash is going to be much more powerful than the pop-up version. Also, there is much more flexibility built into the Speedlight system of flashes than you could ever hope to get from the built-in version.
Nikon currently has several Speedlight flashes for sale, but my recommendation is that you purchase the SB-700 or, better still, the SB-910 Speedlight. They will run somewhere in the neighborhood of $325 for the SB-700 and $545 for the SB-910, which can be a pretty hard pill to swallow at first. The pill will go down much easier once you have used one of these powerful and flexible flashes. Not only will your on-camera flash photography be much better, but you also gain the option of moving to a wireless, off-camera flash system that will give you much more flexibility (Figure 11.16). The great thing about the D750 is that the built-in flash can be used as a commander unit to control one of these more powerful flashes. Not only can you trigger the off-camera Speedlight, but you can also adjust the flash output right from the camera position. By using the menu in your camera, you can adjust exposure as well as communicate with multiple flash units. The possibilities are endless, and your flash photography will definitely move to the next level.
Figure 11.16 By moving my main flash off to the side of the subject and firing through a diffusion panel, I was able to create a beautifully lit portrait.
Exposure compensation for flash
A cool feature worth noting is that the D750 has the ability to separate exposure compensation from the flash level. That means you can shoot in Aperture Priority mode and just use the Exposure Compensation button to underexpose the background without affecting the amount of flash hitting your subject. Here’s how to set it up:
1. Press the Menu button and navigate to the Custom Setting menu.
2. Use the Multi-selector to highlight e Bracketing/flash (A) and press OK.
3. Highlight e4 Exposure comp. for flash (B) and press OK.
4. Highlight Background only (C) and press OK.
Diffusers
While I am covering flashes, let’s discuss a tool that lets you improve the light you are using in your portrait photography. A diffusion panel is a piece of semitransparent material, usually white, that you place between your light source and your subject. The fabric does as the name implies: it diffuses the light, spreading it out into a soft, low-contrast light source that makes any subject look better. You could make your own or buy one of the many commercially available versions. I prefer the 5-in-1 reflector kit made by Westcott. It not only has a very nice diffusion panel, but it also has reflective covers that slip over the diffusion panel so that you can bounce some fill light into your scene. Best of all, the entire system is collapsible, so it fits into a pretty small package for traveling.
You’ll find more information on Westcott diffusion panels at www.fjwestcott.com.
Camera Bags
This topic is tricky because there is no one-size-fits all answer. How much gear you want to carry, how big you are, and your own style will all influence your bag purchasing decision.
I like to travel with my photo gear. Typically, my travel involves flying. This means that all of my camera equipment will be traveling in the cabin with me, not in the luggage compartment. I can’t emphasize this enough: Do not pack your camera in your checked luggage! Thousands of cameras and lenses and accessories are lost or stolen from checked luggage each year. The best way to ensure that doesn’t happen is to bring it onboard and place it in the overhead storage. I like to bring my laptop as well, so I have found a couple of backpack camera storage systems that allow me to fit a camera body, several lenses, some accessories, my laptop, and even some snacks into one backpack-style bag that still fits under the seat in front of me or in the overhead bin. I also prefer a backpack because I like the freedom of slinging the bag over my shoulder, leaving my hands free for other luggage. I have been using a Think Tank Photo Airport Acceleration (www.thinktankphoto.com) for years, and it works perfectly for most of my needs.
My latest favorite bag for outdoor trips that involve hiking is a Rotation 180 Professional from Mindshift Gear (www.mindshiftgear.com). This bag can hold all the gear I need and can do it quite comfortably. It feels and looks like a backpacking bag, but is designed for photographers. Fully loaded up it still fits in the overhead bin in all the commercial flights I’ve taken it on (not sure about commuter jets).
The other bag that you should look into is a more traditional, shoulder-style bag. These bags are made to handle all sorts of camera bodies, lenses, and accessories, and they’re usually completely configurable with moveable padded partitions so that you can completely customize the bag for your own needs. My current bag of choice is the Retrospective 7 (www.thinktankphoto.com). This small-looking bag easily holds a single camera body and two or three lenses, my iPad, extra batteries, multiple memory cards, and plenty more.
These bags are the ones that I am using currently, but finding the perfect camera bag is truly the Holy Grail for photographers. The fact is that you can go through a lot of them searching for one that perfectly fits your every need and never find it. I presently have several bags taking up residence in my closet.
Another company that makes great bags is Lowepro. You can check out the full line of Lowepro camera gear at www.lowepro.com.
Bits and Pieces
Since I just covered camera bags, let me share with you a couple of items that always travel in my bag.
The battle against dust is always a losing one, but that doesn’t mean that you can’t have your small victories. To help in the war against the dust specks, I carry three weapons of cleanliness.
The lens cloth
A good microfiber lens cleaning cloth always comes in handy for getting rid of those little smudges and dust bunnies that seem to gravitate toward the front of my lens. I use one called a Spudz, which folds into its own pouch and has the added benefit of being gray. This means that I can use it as a gray card to get meter readings in Spot metering mode, or as a way to correct the white balance in my images down the road when I bring them into my imaging software.
More information on Spudz cleaning cloths can be found at www.alpineproducts.com.
The LensPen
For really stubborn smudges on my lens, I pull out my trusty LensPen (Figure 11.17). This nifty little device has a soft, retractable dust removal brush on one end and an amazing cleaning element on the other that uses carbon to clean and polish the lens element.
More information on LensPen products can be found at www.lenspen.com.
Air blowers
Some folks prefer to use canned, compressed air to blow away dust, but they can sometimes release fluid when the can is tilted. For this reason, I always use my Rocket-Air blower from Giottos (Figure 11.18). This funny-looking device is great for getting rid of tough dust, and it uses a clean air path so that the dust that you are blowing away doesn’t get sucked into the ball and redeposited back on your equipment the next time you use it.
Better LCD vision
Having a large LCD screen is an amazing thing. The only problem is that it can be very hard to see in bright daylight conditions. The way I overcome this is by using a Hoodman Loupe. The loupe doesn’t magnify your screen; it just provides a light-tight little tent for you to get a better look at your rear LCD. It has a handy little lanyard so you can just let it hang around your neck and keep it within easy reach for checking out those great shots you just took. If you are going to work out in the bright sun, you will definitely want to get yourself one of these for your camera bag.
To check out all of the Hoodman accessories, head to www.hoodmanusa.com.
A Word About Lenses
As you venture forward with your D750, the choices you make about which lenses to purchase will have a big impact on your photography (and your wallet). It is very likely that your lenses will outlive your camera body, so if you see yourself commited to photography for the long haul, I encourage you to consider investing in professional-quality glass to get the most from your new full-frame camera (or FX, as Nikon refers to it). The good news about the D750 is that it is compatible with a wide range of lenses. Check out pages 426–432 of the PDF manual for a list of compatible lenses.
Just because the D750 is a full-frame camera doesn’t mean you should rule out your old crop-sensor (referred to by Nikon as DX) lenses right away. The lens you have is better than the one you don’t. If you have DX lenses, you can go under the Shooting menu to Image Area and set Auto DX crop to On (Figure 11.19) so that the D750 will automatically switch to using just the center of the sensor when a DX lens is attached (and recognized). This mimics the same 1.5 crop factor of DX camera bodies and reduces the effective pixel count to around 10.3 megapixels. See pages 110–113 of the PDF manual to learn more about choosing the image area.
Figure 11.19 Setting Auto DX crop to on ensures that the D750 will use the center of the sensor when DX lenses are recognized.
A good way to try out a lens before you buy is to rent it for a weekend and put it through its paces. If you don’t have a local camera store, photo studio, or friend that offers this service, there are a growing number of online rental agencies to check out. My favorite place to rent from is www.lensrentals.com.
Conclusion
You can spend a lot of time worrying about having the right gadget, filter, or accessory to make your photography better. It can become an obsession to always have the latest thing out there. But here’s the deal—you already have almost everything you need to take great pictures: an awesome camera and the knowledge necessary to use it. Everything else is just icing on the cake. So although I have introduced a few items in this chapter that I think will make your photographic life easier and even improve your images, don’t get caught up in the technology and gadgetry.
Use your knowledge of basic photography to explore everything your camera has to offer. Explore the limits of your camera. Don’t be afraid to take bad pictures. Don’t be too quick to delete them off your memory card, either. Take some time to really look at them and see where things went wrong. Look at your camera settings and see if perhaps there was a change you could have made to make things better. Be your toughest critic and learn from your mistakes. With practice and reflection, you will soon find your photography getting better and better. Not only that, but your instincts will improve to the point that you will come upon a scene and know exactly how you want to shoot it before your camera even gets out of the bag. If you’d ever like to get some hands-on practice in the field, I’d love to have you join me on a workshop.
