I am very well aware of Moiré patterns and why they happen when taking photos of computer/phone screens. However on the website of some software projects there is a photo of someone using the product behind a screen (phone or computer). Yet I never see any Moiré pattern on the screen.
My knowledge of photo equipment is lacking. I believe most of these photos are just screencaptures photoshoped onto the screen.
My question is: is there any chance these photos are authentic? I am not asking to reveal the secrets of the trade, but is it even possible to eliminate Moiré patterns when taking photos without post-processing?
