I am also a photographer and use Photoshop to enhance and adjust all of my art and client services.
If you want to see some of my work, please check out my website: www.mexploration.net. I have a Gallery section of my art work, but also have a section on Portraits. I teach Photoshop and in the section on my classes, I have a Before and After sub section showing my original photos and the final results.
I know you said that you use TIFF files. Are you going to send TIFF files or just want the final result converted to TIFF? Also, do you shoot in RAW? If you do, it would be easier if you could send me the RAW files along with the jpegs. That way, I could see the original in jpeg, but could work with the RAW image to capture some of the detail that jpeg doesn’t have, such as the “white out” when there is a window to the outside.
I looked at your website and would love to work with you on adjusting your photos. I am new to this Freelancers site, but hardly new to photography and Photoshop.
I hope to hear from you.
