thank You for taking the time and visit our forum. I much appreciate reviewers doing that.
I also like how you replied to the rotation issue when a new member (nickmeertens) challenged you in a childish way (back to school) and later "forgot" to apologize when proven wrong.
BTW, you're right, rotation for angles other than multiples of 90° decreases image quality. Rotation by 3° can increase the blur width by as much as 10%.
Thank you Falk!
I appreciate everything you said. My goal is to provide information and dissipate misinformation, of which there is plenty around but I wouldn't follow any discussion turning childish. Only people with an open mind will listen and learn.
Forums are valuable for photographer educators because they tell us what issues people are having. How else would we know? Actually, nearly every article on Neocamera is a based on a frequently recurring forum or email questions.
I learned from this very thread that people don't understand rotation of digital images, someone even thought it was simply a form of cropping (but we can't crop in arbitrary directions without re-interpolation). I happen to know how it works because I've spend 9 years working on an image processing pipeline for film special effects but most people don't know that about me. At least I don't have to write an article this time because someone pointed to the Cambridge In Color link which illustrates the process well
Thanks again and to everyone else who expressed their support!
