Photo Forum / Digital Photography / DSLR Cameras / July 2006Canon DRebel Disappointment
I am trying to take a picture of a fluorescent mineral. I need to suppress the built in flash control the aperture for depth of field set down the exposure compensation so the highlights don't get blown-out the DRebel does all that, only I want to do all three at the same time. I kind of miss the control I had with my old Vivitar 450. > I am trying to take a picture of a fluorescent mineral. > [quoted text clipped - 7 lines] > the DRebel does all that, only I want to do all three at the same > time. Have you read your manual?

Spent some time with it last night, that's how I'm sure that I can do any one of these things at a time, but not more than one. At least that's all I could get out of the manual. >>>I am trying to take a picture of a fluorescent mineral. >>> [quoted text clipped - 15 lines] > can do any one of these things at a time, but not more than one. At > least that's all I could get out of the manual. They're 3 entirely different controls on the Rebel XT and I believe they were the same on the Rebel although I haven't had my Rebel for quite some time. Turn off the flash, set the mode to aperture priority, and lower your exposure compensation.

On my DRebel the mode knob on top lets me select Av, or no flash (among others). Exposure compensation doesn't seem to work in "no flash" mode, it only works in the creative modes. I just read the manual again, and tried it. No flash isn't a creative mode. I can overpower the aperture setting problem by using an older Pentax type lens, but I still have the conflict between flash and exposure compensation. >>>>>I am trying to take a picture of a fluorescent mineral. >>>>> [quoted text clipped - 32 lines] > type lens, but I still have the conflict between flash and exposure > compensation. Uh, does the flash pop up automatically in Av mode? According to the manual it is not supposed to in any of the "creative" modes unless you explicitly press the flash button.

You know, I have to wonder if you even have the camera. Have you even tried it? My brother has the camera and I have used it (I own a Nikon D70). I had not issue doing the basic things you were talking about and I didn't even need the manual (no offense). SignatureThomas T.

First, set the camera to one of the creative modes. Don't use the basic modes, they'll just screw you up. Since you want to control aperture, use Av, then you can set the exposure comp as you want, and the flash won't pop up on its own. Anyone who's serious about getting the right shot won't use the basic modes, anyway...

I believe GT is correct, since most DSLRs have this ability, it should be explained in the manual. This how I would do it: Set it to aperture priority to control the depth of field. The flash will not fire when it is down. Dial in the amount of negative EC you want by holding down the +/- button and turning the control dial. Use a tripod or stable surface if the shutter speed is too slow. Snap away... >>> I am trying to take a picture of a fluorescent mineral. >>> [quoted text clipped - 22 lines] > >Snap away... Hey, that worked! thanks. Not sure why the flash stayed down, but it did. Exposure was 30 seconds with room lighting, now to play with things and see if I can get a good picture. Thanks much. >>Set it to aperture priority to control the depth of field. >> >>The flash will not fire when it is down. > >Hey, that worked! thanks. Not sure why the flash stayed down, but it >did. If you check your manual again, you'll find that the flash will not automatically pop up when you're in any of the creative modes (P,Tv,Av,M). But if you want to use flash or fill, you just tap the flash button on the side and it pops up ready to go. >>> I am trying to take a picture of a fluorescent mineral. >>> [quoted text clipped - 22 lines] > >Snap away...

Oh, by the way, you just ruined a good excuse for me to buy a new camera. Hope you're happy. :-) >Oh, by the way, you just ruined a good excuse for me to buy a new >camera. Hope you're happy. :-) Why buy a new camera? The Rebel is a fine camera with plenty of features and good image quality. The only reason I would consider upgrading would be for a larger buffer when shooting sports or a specific feature the Rebel lacked. My first digital SLR is the Canon Rebel XT, but I think I would have been happy with the original if I had moved to digital sooner. Besides, the glass on the front of the camera is usually more important to image quality than the body. >Besides, the glass on the front of the camera is usually more important >to image quality than the body.

Put it in apeture priority and stop down the lens. Do not activate the built-in flash ... not too tough. Use exposure compensation at will. SignatureThomas T.
