It is obvious that Photoshop does magic sometimes. I have had useless photos (underexposured, etc.) which became acceptable after processing with Photoshop (level, contrast ... adjustment).
- In this image processing course in CS postgraduate they would say: "Any type of image processing will remove information from the image". This has caused me to be extremely cautious on using Photoshop on my photos. I look at it as a sin or cheating
- However in some circumstances, using Photoshop and similar software is inevitable because some photos need improvement otherwise they are useless.
The question: "What is the red line in using Photoshop? When it is considered professional to use it and when it might be considered as unprofessional??"
I appreciate your opinions.
