Hello I am new to this site and a bit lost. I photograph birds and other wildlife mainly, I use a Nikon D90 and a Sigma 150 - 500 mm lens and hope to upgrade in the future, I also use smaller lenses. I am hoping to get advise on editing with photoshop I use CS4, I drive from southern California to Idaho at least 3 times a year and take photos along the way. I shoot mainly at our local wetlands in sothern cal.
Thanks for any future comments.
