Rob Phillips Group - Gel Camera
We use a Sony Cybershot digital camera for taking pictures of EtBr-stained gels in lab. Here are the instructions:
- Center your gel under the camera using the rubber pieces
- Find the computer that has the memory card, delete the pictures
- Right-click on the icon and select "eject", wait for it to finish working
- Put the card in the camera, turn it on
- Check settings:
- Wheel is set to "M" for manual exposure
- On screen: f2.8 - ISO100 - FINE/2560
- Focus set to "manual" on the lens barrel
- Use the ridged black focus ring on the lens to adjust focus to 0.32m
- Select a desired exposure time with the little wheel (1-5"). Note: numbers without the second marks indicate fractions of a second!
- Press wheel down to adjust the exposure time
- Turn on the timer by pressing the down arrow
- Turn on the ultraviolet lamp
- Zoom with W and T on the lens barrel (halfway is good)
- Press the trigger and stand back
- When the camera displays "processing" or a final image you may turn off the lamp to prevent photobleaching
- Set the wheel to play mode to inspect your image, take more if necessary
- Turn off camera, look at pictures on computer
