I just moved. so in a few week's hopefully I'll be taking shots of my new tank.

thanks for the advice, i'm going to look into on how to clean my sensor and seting up custom whitebalance for my next shot, along with trying to focus better.

A probelem with the focus could be if you're using the camera's "beep" for focus, and that will be wrong when using tubes. At least it is on my camera. My camera defaults to infinity focus as soon as a lense is connected using an adapter.

I brought my camera in and there is no problem with a dirty sensor but a permenent problem with the sensor. stuck or dead pixel's, so I played around with photoshop and it seems that I can get away with it by bluring the image and adding noise to a small area to make it look decent in photo shop.

not sure how this will effect the pic if I choose to develope it?


either way I will just use this camera to learn from before buying another if I do.

in the next few day's I will post some pic's.

finaly I am settled down in my new place to take pics


I got a free photoshop when I took my computer in to get cleaned, but now I am learning to use windows 7, firefox etc so things are a little different, just learning this. i'm switching from internet explorer,xp, oldschool.

What do you mean by "beep's"

A cheap trick for getting rid of camera shake on longer shutter speeds is to use the self timer, or you can take it through EOS Utility.

Eos Utility works under Windows 7 64bit for the live view and camera control. Lightroom is much better for shooting tethered though .

Subject: pink recordia yuma

Working with:

canon eos rebel xs 1000d, lens 18-55mm, 50 mm nifty fifty, and the kenko extension tubes 12mm, 20mm, 36mm.

Not sure where to start regarding size of tubes and lens?

I have a tripod and computer live remote shooting with a laptop. but I also have a wired hand held shutter button, if needed?

My subject is approx 2" from the front glass in the middle of the tank under 6 t5 h.o and I can get my camera right against the glass.

Should I shoot in the dark with tank lit?

I'll be turning the pump's off. besides the very low flow lift pump, in the back.


Where should I start with shutter speed to maximize detail in the pic?

subject is at the same angle as the front glass.

And I want to maximize the subject so she fill's the frame, where should I start with the aperture?

what len's and what extension tube/tube's?

mirror lock up?

I see that some people put a black background. can this be done through photo shop convincingly? or is it better to use black acrylic/plexiglass before taken the image?

Use tripod and some kind of remote, either the laptop or the wired remote, which ever.

I would use the 50mm, not sure which extension tube combination will give best results but I would try a few combinations until you get the subject within the the full frame and still have some focus tolerance on both sides.

I would use aperture priority mode starting at about f16, shutter speed will be determined automatically but if you find the shoots over or under exposed simply adjust your exposure +/- setting accordingly. Remember aperture controls DOF and ultimately how much of the subject will be in focus, shutter speed doesn't really control anything related to detail provided everything remains perfectly still.

Manual focus as previously discussed, focus on the center point of DOF on the subject to maximize overall DOF. Mirror up could be a good idea, but again but if your tripod is decent you shouldn't need it. Mirror up may be automatically selected if you're using a laptop with a live preview.

Remember to set the WB, minimize ISO, and shut off all tank movement and room lights.

For blacking out the background experiment with smaller apertures (remember that means higher f number) and longer exposures. You may notice that the background becomes darker but it's pretty hard to completely black it out with the camera only so you'll have to finish it off in photoshop.



You can do it completely manually as well using photoshop by making multiple layers and using the quick selection tool.
