Re: discoloration of jpg

Not sure of your problem. You want to convert tiffs to jpgs, but you 
show a jpg image. What are you starting with? Can you provide a link 
to your original tiff and a badly converted jpg.

When looking at the image you provided, it has profiles in it. That 
may be the cause of the problem.

You need to either use the correct profiles to convert the image or 
add -strip to your conversion to remove the profiles.
