Here are som etips for you with your camera. After reading this sit down with your camera and try to take some pics with these tips. Whatever you don't understand ask about and I will dial you in to where you can take very nice pics.
For camera settings I recommend....
1. Set your white balance before you take the photo. You will get better color resolution in the pic.
2. Set your iso to 400 if possible/
3. Set your lens to MACRO. there should be a flower/tulip icon.
4. Get the camera as close to the tank as possible and then zoom in as close as possible while maintaining focus.
5. Make sure the outside glass is clean and that the algae has been removed also.
6. Make sure the room is completely dark except for the tank lights.
7. Take one pic w/flash and one without.
8. Try taking one pic on auto setting w/macro and one in manual setting...M...SHOULD BE THE ICON.
9. If you use an slr use a 105mm lens.
For Photoshoppe...
1. adjust levels first.
2. Adjust contrast second.
3. Adjust Hue/saturation next.
4. Adjust Photo filter color temp next. If you don't have this feature don't worry.
5. Adjust size next. 450X325 is good with 10 as file size if it ask about quality.
6. Adjust sharpness last after resizing. Adjust sharpen edges. That should be enough.
If you ever need photos shopped for you send them to me in PM and I will edit and send back.
