Truthfully, I seldom check for CA. They don't bother me as much as e.g. complex curvilinear distortions, etc. Even if there is CA, it can be correctly in post.

A security personnel on motorcycle approached me and asked where I was from and why am I taking photos. Just a few minutes into my shutter therapy session. It shows there are lots of CCTVs at Biopolis. LOL.
not that i'm against image sharing, but perhaps qx3007hi you could create your own thread in the APAD section or in the landscape / street sections to share your captures.
After all this is a thread created in the "review" section.
