Troubles with Nikon D70s SLR
This is kinda off topic however it does relate. I'm looking for someone local to connect with that has a D70s SLR to share some tips and tricks taking photo's of tanks with. I also think there may be something wrong with how my camera is metering light and i wanted to compare with someone who has the same camera.
Anyways shoot me a PM maybe we can both learn something new. Kyle

I have the same camera, but I guess we're not local to each other. Check with Raf or Diana though, I think they shoot with that model as well and they'd be closer.
Tank photography is tricky - I used to think I was OK at photography until I started trying to shoot my tanks. Now I realize I'm horrible at it. Anything non tank related seems to go well though. I guess the lighting really throws things off. A lot depends on what glass you're using too. What lens are you using? If not doing so already you should probably consider shooting with a macro lens and not bother with anything else. When I was shooting with my 35mm I had a 90mm macro lens and it worked out well. Moving to a DSLR body though puts a 1.5x magnifier on your focal lens so it became the equivalent of a 135mm. Which is great if you want a photo of maybe nostril on a snail but not so good if you want a picture of a whole animal. I found I had to step so far back from the tank to fit a fish it kind of defeated the purpose of a macro lens. After reading this thread, http://www.canreef.com/vbulletin/sho...d.php?t=36153& .. I started saving up for the F2.8 60mm Macro lens. Found a good deal on ebay. I have to say, this is a great lens. It's more or less the standard micro (Nikon's term for macro) lens that Nikon offers nowadays. Highly recommend looking into this lens (if you're not using it already that is  ).Lastly, practise is underrated  Seriously, I find I'll shoot some 90-100 pictures in a sitting and keep maybe about 4.  I guess I need those tips too, but in the meantime, shoot lots and vary it up and see what works well.Anyhow good luck, hope some of this helps.

the biggest problem with Tank photography is the multipule colour temperatures in your tank. Actinics through a lot of light into the tank, but most meters do not read that colour temp. Try turning off your actinics.
Also the dinamic range of digital is far narrower that say Film. So with such stronge lighting and high contrast it is impossible to capture white sand and high colour definision in corals. there is just to great a difference in light reflectance. Basically if you meter your sand you get (for example) f 2.8 @ 1/1000sec. Then meter the coral you are attempting to capture. it will meter at f2.8 @ 1/60sec for example. this range is too high. Your best bet is to switch to spot metering and meter your subject only and let the rest fall where is may. What you can also do is shoot raw. This will give you 16bit file to play with (jpg is only 8bit) you will then need to use a RAW formate tool like Adobe Lightroom or what ever came with your camera. you can then manipulate the 16bits of data into the 8 bits you need to make the best picture you can. Hope this helps J

Tagging along. I also have a Nikon, but its a D40x and not a D70. However I'm sure there is tons to learn either way.
Have you thought of checking any books out of the library on the subject?

I got a Sony Alpha 100 DSLR and from the 2 or 3 days I've had to play around with it I'll second the recommendation for spot metering. Is RAW the preferred format for shooting?
