That's not to say it's impossible; I just don't know how one would do it. If you can figure that out, then it should be very easy. I think it's worth noting that the important thing is to use color universal design when it's possible that the information in your graphic is difficult to use. Unless you're using your photographs as part of a larger informatics project, it might not be necessary to simulate them this way at all.

Can you help me step by step how to do the conversion in photoshop. Thank you once again. Regards Vijay Hello Jeff

I”am a photographer I would like to thank you for putting across the article on the net and I curse myself why I never thought of making pic for such people all these years, I will make an effort to convert the rgb files into protanopia,deuternopia files.

Can you help me step by step how to do the conversion in photoshop.

Thank you once again.

Regards
Vijay
