If you’re looking to capture high-impact underwater photography without the backscatter, an ultra-wide lens and closeup photography are your secret weapons.<\/p>\n

Top: This is one of my favorite underwater photos of a brown booby investigating his reflection in the super-domeport when using my Canon 15mm fisheye lens. Canon 5D in a Seacam housing. Above: This image was shot in Papua New Guinea of a coral cod resting in a sponge formation. The fact that the 15mm fisheye can get close and show the \u201cbig picture\u201d is an advantage of close focus wide angle (CWFA, as we pros call it) underwater photography.<\/p>\n

\"Leisure<\/a>Many years ago, one of the most fun and challenging formats in underwater photography was using the trusty underwater Nikonos camera<\/a> with the 15mm wide angle lens. Today, using my DSLR (Canon 5D Mark II<\/a>, available at Adorama) in a Seacam underwater housing, this is still is one of my favorite set-ups. For beginners, this may be something you may want to wait on until you get a little more experience with a medium wide-angle lens. Where the medium lenses can give you a pleasing scene, it\u2019s the ultra-wide angle lenses that create drama.<\/p>\n

Whatever system you use, the idea is to get close, but do know your animal behavior! Top: The moray eel was not agitated at all. He was curious about the dome port. I was only about a foot from his face and still captured the scene. Canon 5D Mark II<\/a> with 15mm f\/2.8 (Although the Canon 15mm f\/2.8 has been discointinued, Sigma makes a 15mm f\/2.8 lens in Canon Mount<\/a>. Read on to see which lens I’ve been using lately!)

What lenses are out there that can capture the ultra-wide scene?\u00a0 The first question to ask when looking at brands and width is \u201chow close does it focus\u201d?\u00a0 That is because in underwater photography the mantra is \u201cGet close \u2013 then get closer\u201d. The less water you have in between your lens and your subject, the better your chance of avoiding backscatter<\/a>. The clarity of the subject is also heightened especially if the visibility is not at its best. It is very important to get as much contrast and detail as possible to maximize the impact to the viewer, especially if it is a dynamic subject!<\/p>\n

Both of the above images were shot with the Canon 15mm fisheye. Your composition\/position will determine just how much barrel distortion shows up. The closer to the edge of the frame the straight lines are, the more bend you will get.<\/p>\n

My favorite lens is a fisheye. For CFWA, it is the lens of choice for both DSLRs and compact cameras<\/a> since they are unmatched when it comes to focusing very close. The Nikon 10.5mm f\/2.8G ED-IF AF DX Fisheye Nikkor<\/a> lens, available from Adorama<\/a>, is designed for cropped sensors; The Tokina 10-17mm lens<\/a> is available from Adorama<\/a> in Nikon and Canon mounts. I have used the Canon 15mm f\/2.8 fisheye lens (discontinued, alas) for years. The most crucial part of lens selection is what works well with your camera body and the proper dome port!<\/p>\n

\"Wide<\/p>\n

Sometimes it\u2019s just fun to experiment with the curves that show up using a fisheye lens. Canon 5D Mark II<\/a>, Seacam housing, Canon 15mm f\/2.8 fisheye lens and dual strobes.<\/p>\n

The lens behind a dome port does not focus on your chosen subject as it does with your terrestrial ones. It is a virtual image about 9 to 12 inches in front of the port. What the heck is a virtual image?<\/p>\n

Wikipedia says it is an optical image is formed from the apparent divergence of light rays from a point, as opposed to an image formed from their actual divergence. Translation: In underwater photography, the camera sees the image much closer than it really is. You can test this out by manually focusing your wide-angle lens\u00a0 about 5 feet in distance on a topside subject, then taking it in the water and photographing a subject at the same distance. The result will be that your underwater subject will be blurry.

Wrecks make the perfect subject for close focus wide angle. You can capture the entire scene and only be a few feet from the bow. Then you can head to the interesting areas, such as this wheelhouse, and get vibrant colors of encrusting sponges and fish life. I made sure my strobes were at the\u00a0 3 and 9 o\u2019clock position with diffusers on them to help spread the light more evenly.<\/p>\n

Another thing to consider is that just because a lens may fit behind that dome port you recently purchased, it doesn\u2019t mean that it will give you a sharp image or eliminate vignetting. It is imperative that you follow the housing\/dome port manufacturer’s recommendation for the port and\/or any spacers.<\/p>\n

Exposure<\/p>\n

Set your mode to manual!\u00a0 Why?\u00a0 It will be impossible to get the right exposure for the background, especially the water column, and your subject. The shutter speed controls the background while your strobes will light your subject. I tend to use my spot meter and measure off the blue water, then check the histogram on the back of my camera for correct exposure. If the background is too bright, use a faster shutter speed and vice versa.<\/p>\n

Depth of field will play an important part in CFWA. Use an aperture of f\/8 or smaller. Typically, with bright ambient light on my full frame sensor SLR, the best results are achieved at f\/11-16. You may be a bit restricted with a fixed lens compact system and wide-angle adapters since some are set with f\/8 as the smallest aperture. I usually set my aperture and leave it on a dive then make my adjustments to the background via shutter speed. I can light my subject using techniques in the next section.<\/p>\n

Both of these images were shot by metering off the mid-toned\u00a0 blue water first. Once that was determined, it was a matter of adjusting strobe power and positions to light the subjects. One area with the shark and sponge was lit directly, where the seafans had to have the diffusers on the strobes and set at full power due to their light-absorbing qualities.<\/p>\n

Foreground-Subject Lighting<\/p>\n

Strobe power and position is the all-determining factor in successful CFWA. For many years, the thought was to have strobes placed on very long arms quite a distance from the port. This was great for large animals, but did not properly light a very close or smaller subject. Dual strobes are important but you can also get away with using just one. My strobe arms are set up using two on each side but not so long that I can\u2019t pull them in tight to the housing. Many times, strobes on longer strobe arms will over-light the sides of the image, leaving the subject in the shade. Of course, if they are too close to the dome you might see some backscatter.<\/p>\n

Pull those strobes back and behind the dome or housing to avoid flare. Using diffusers will also help spread the light with a softer wash over a larger area. However, if you are as close to the subject as the lens allows\u2014in some cases only inches\u2014then you will most likely have to reposition your strobes to provide more light directly on the subject. This can be tricky and you will have to experiment a bit. Shooting horizontals is the typical format people use in this case. Placing the two strobes on either side of the port (at 3 & 9 o\u2019clock) and slightly pulled back while pointing straight ahead is a good starting point. You may want to point the strobes slightly inwards when the subject is less than one foot from the front of the dome.<\/p>\n

Both shots using the 15mm fisheye and only about a foot from the subject. Because the turtle (top photo) was at the surface of the water, only a tiny amount of strobe power had to be used to light up the details of the face and underbelly. (ISO 200, 100 at f\/11 with strobes at \u00bc power)\u00a0 The barracuda (above) is a very reflective subject, so I also had to dial down the strobes to \u00bc power.<\/p>\n

Don\u2019t forget to try vertical formats!!\u00a0 This requires a little more practice with strobe placement. A common problem that occurs if the strobes are left at the same position (now in the 12 & 6 o\u2019clock) is the bottom strobe will put too much light on the subject and look a little unnatural. Ambient light comes from above, not below. It is also common to impede your ability to get low enough to the subject since the strobe is in the way. Move the strobe to either the 12 & 9 or 12 & 3 o\u2019clock positions.<\/p>\n

Shoot both formats\u2014vertical and horizontal!<\/p>\n

Strobe power is another crucial decision. I use my Ikelite DS 161 strobes<\/a>, available from Adorama<\/a>, which have power settings that are easily accessible. I may use full power on a light hungry soft coral or seafan, then dial down the strobe to 1\/2 power or less for a smaller subject that is only inches from the front of the dome port. The brand of your strobe can also determine just how much power you want to use. I have found the only true way to know for sure is to get out there, find a static subject such as a sponge, nudibranch or other inanimate creature and practice using all the setting choices you have.<\/p>\n

Placing your strobe can be a challenge to get the light to look normal\u2014that is, from overhead. Also watch for shadows created by other objects blocking the light direction from the strobe. The above sequence shows the effect of moving strobes to provide more natural-looking light. ISO 320, 1\/60th second at f\/8.<\/p>\n

Earlier, you heard me say that over the years, I\u2019ve used the Canon 15mm f\/2.8 fisheye lens. Well, I put her to rest a couple of months ago-not that she wasn\u2019t a good performer!\u00a0 My new toy is the Canon 8-15mm f\/4.0L USM Wide Fisheye Zooom Lens<\/a>, available at Adorama<\/a>. What I have discovered is that in combination with my very small glass dome port and its ability to focus frighteningly close, the images are very dramatic. I\u2019m still in the experimental stage and lighting is an ongoing learning curve. But the fact that I can get into tight spaces with such a wide view is amazing. I have been using the lens from the 13-15mm range because I really don\u2019t care for the vignette that is produced at the wider zoom settings. The best part? My subject is tack sharp. Don\u2019t worry if this was a lot to digest; I\u2019m sure to revisit this subject in a few months.<\/p>\n

What in the world does this have to do with underwater photography? It\u2019s the only image I had in my files that shows what the new Canon 8-15mm fisheye lens does when it is shot at its full fisheye capability\u20148mm!<\/p>\n
