I currently have a canon 100D (I'm not a photographer - I own a business and do my own product photography because of budget constraints). The moire shows up on solid colour garments.
I have tried everything including zooming in/out, changing the camera angle, focusing somewhere else in the frame, using a large aperture, etc. I have even tried removing it in lightroom, although the artificial colors go away, unfortunately the texture is still affected.
I have heard the 100D has an anti-aliasing filter to prevent moire, so I'm not sure why it is still happening. I wanted to invest in a high resolution camera such as the Nikon 7100D - would it be worth it?
