I have no professional training with photography, and have basically been lucky to have a really brilliant camera. I have learned, over time, some techniques that help capture the colors and give a photo an eye catching angle. However, editing seems to be the tool that truly differentiates a fabulous photo from an average one.
Often for one piece I can take up to 40 to 50 shots to get just a couple good ones to work with. This is a lot of work! I have recently started playing around with Photoshop, to be able to perfect color and hue, and today I stabbed at altering one photograph to suit a listing for 5 different colors. I have a pair of Czech glass poppy earrings, available in a multitude of colors, I literally took 30 different shot of me wearing each color, and came up with only ONE outstanding shot.

Here is the original photo. I like the feel of this photograph, but wasn't sure I could reproduce it for each color, as it is difficult to photograph myself with my DSLR camera. So I turned to Photoshop for some editing help. Below you can see that I have switched to black and white, increased the brightness and and contrast, and then adjusted the hue to match each color that I have to offer.



I have only attempted this because these earrings are all identical in size and proportions. I have also been very careful to modify the hue to resemble the color I have available, to make it an honest interpretation.
