After bringing your photo into Photoshop from your digital camera:
1. Decide if the photo needs the brightness (lightness) adjusted: look to your white background for reference - it should be white in the photo and and also check the digital image against your original piece of artwork.
2. If photo needs to be lighter, go to Image/adjustments/brightness and contrast and move the top knob to the right while keeping an eye on the image. Move it until your white background looks whitish, and your image looks close to the VALUE of your original. You may also have to move the brightness down a little if your image is overexposed, which should not be a problem as long as you don't take the photo in the glare of full sunlight.
3. Next decide if your image needs color adjustment.
4. Go to Image/Adjustment/Hue and Saturation in Photoshop. Play with the Hue if color is off while watching the preview of your photo. Usually the hue does not need any major changes, but possibly a little tweaking. Watch as the Hue of the entire photo changes from green to red and goes through the whole color spectrum to adjust the image. Again compare the photo to your original art.
5. Don't forget to save your image as you go!
That's usually all I need to do to the image to get what I need. The camera with the right outdoor light does most of the work for me.
