Taking Agarose Gel Pic with Regular Digital Camera - (Feb/11/2008 )

if you have anything on your gloves that could damage a lens it means the cheap screw on filter takes the damage rather than the lens itself (if your not so messy you may be ok - but dont forget undergrads)

Hmm, I'm a bit worried.

I set up my Canon A70 for taking gel pictures. It goes through the same filter the Polaroid gel camera was using. Seemed to work quite well. I did a dose response and checked out the intensities on the digital camera picture as well as a polaroid picture (which was scanned into the computer). The digital camera seemed equal or better than the polaroid.

....However, today I was taking another picture. The first one I took was okay, then they got dimmer and dimmer as time went on. Even when I increased the exposure time, the picture was washed out and blurry compared to the first one.

Is my camera being damaged?

I noticed afterward that my batteries were almost dead (actually died right afterward, haven't got an ac adaptor yet). Could this be the problem? I hope it is, because it would stink to only be able to take a couple pictures before the camera wears out.

The three attached pictures are from from the first shoot, the first one from today's shoot, and the last one from today's shoot.

it does sound like the batteries (not that impressed with them - are they a block or standard rechargeables - a high drain type mh2300 might be better - rechargeables tend to cut off sharpish while disposables reduce in efficiancy)

It was the batteries , just to update.

May have also been the autofocus.

I was wondering if people thought I could use the setup to capture western blot chemiluminescence?
