I disagree. My friends using higher resolution cameras call me Pixel Peeping too when I do that.
Everyone, whether with high or low resolution cameras, do at some point in time, zoom in all the way to check the details of their images.
I don't see anything wrong being called Pixel Peeping. All photo retouch artists do that do!
When I say, "20mp is enough for me unless you pixel peep", I don't mean to be derogatory as I am referring to myself.
Most of my images are meant for Photobooks and Social Media.
Photobooks are A3 size or smaller (most are A4) and usually printed at 300dpi for high quality prints.
I have done comparisons before with higher resolution cameras and it is not easy to tell the difference on the output of photobook pages.
So, there is not much point for me to shoot beyond 20mp, unless there is a need to.
I still have my good old Canon EOS 5D mk2 and Sony A7R I have never been disgruntled about it or see it as obsolete, as it continue to deliver
good images for our clients reliably!
I think it is your statements which are derogatory, calling people with low MP cameras, disgruntled and with obsolete camera.
Cameras are never obsolete as long as they are able to provide good images. Dont be caught up with all the marketing hype of
having to upgrade to the latest camera bodies and accessories.
The phrase "Pixel Peeping" was probably invented by some disgruntled fanboy of outdated obsolete cameras who wanted to defend a low MP camera.
The phrase "Pixel Peeping" is derogatory and insulting to anyone who checks his photos at high magnification.
