From 2012 and a reminder that Olympus lenses, even the kit ones, were excellent. Taken with a E-410 an early 4/3rd sensor camera. I can't work out why I didn't walk out on the foreshore to remove most of the foreground clutter and produce a cleaner image of the water, castle and sky. 2 different crops. Ken

Thanks for joining in Ken, and a lovely example. I like them both but the second is preferred.

I decided to try my luck with shooting from my drone at sunrise and can now say that the camera has some serious issues in low light. There were some curious artifacts in the RAW file including some color shifting along the right hand side of the image that required some localized color corrections using a radial filer. The dark areas in the scene need to stay dark after what I saw when I tried to brighten them up and that was after using Topaz Denoise AI to try to clean the shot up. I might be able to recover more at home but this was the best I could do using my laptop on the road.

Nice image Alan. Leaving the blacks was a good choice.

A 1/2" Quad Bayer sensor to pack 48MP will struggle in low light. Does down sampling to 12MP help with noise? Is there an option to switch to 12MP (they do pixel binning)?

Jameel - The 48mp sensor configuration doesn't merely struggle with low light and a wide dynamic range - that was a flat out face plant. Yes I can drop this to the 12MP Quad Bayer configuration and after what I saw on my laptop after this morning's session I should have done that with this kind of light. Lesson learned. The reds in the shadows wasn't the worst of it - the sky in the upper right had an odd greenish cast to it that I had to mitigate as well.

Interestingly when I had the drone facing the opposite direction the images came out fine so the wide dynamic range of the sunlit areas and the dark shadows may have contributed to the issues in the captures. The 12MP Quad Bayer configuration design was originally developed to mitigate the problems that phone sensors encounter in these kinds of conditions.
