What do you mean by this? Mentally unhealthy? Bad for the eyesight? Radiation poisoning?
Speak on this. I have the same concerns.
We're probably safe fron radiation
Eyesight has to be affected by constantly focusing on the same plane. Posture gets messed up - My shoulders/traps ache like hell after a few hours.
For me one of the major problems I have is the same as when I used to print my own black and whites. I'd print some, leave them overnight to dry. Look at them in the morning and figure I could improve them. So that process would repeat until I'd hit the deadline to get them done. I don't think I was being a perfectionist, I was just a lousy printer
I now do the same with Photoshop.
