Support I love Frank's photos of the old restored lighthouse at Point Reyes, especially this photo of the lens. The colors and details are so beautiful. It's the kind of photo I would like to print and hang on a wall at home.

Since the photo is of the lens and not the light device, I've put it in the 'Optical devices' section and not 'Lamps', hope that's ok. -- Cart (talk) 18:53, 28 March 2020 (UTC)[reply]

Comment: quite a lot of technical issues: lots of overexposed parts on the right, strong CAs on the right, strange artifacts (dust spots?) at the base on the left. --The Cosmonaut (talk) 14:11, 29 March 2020 (UTC)[reply]

The small things you call artifacts, were shadows left over since I corrected the perspective for Frank. My bad, now fixed (refresh the page). The highlights add to the natural look and I'm not sure removing any more CA would be a good thing. I wouldn't call it "strong" and the color is so close to that of the glass so you risk getting those ugly gray areas. Better to leave it be, it doesn't disturb the overall impression. --Cart (talk) 14:58, 29 March 2020 (UTC)[reply]

I was referring to the large gray blotches, not the shadows; added notes. I could live with the overexposed areas on the flanks, but the central ones, in the lens, are disturbing. And I don't quite get the argument that removing CAs may make things worse. Sure, any post-processing may make things worse. That's why we hone our skills to improve things. --The Cosmonaut (talk) 15:23, 29 March 2020 (UTC)[reply]

Ok, two dust spots removed and some CA. I think I managed to avoid intruding on the glass color. What you read as shadow noise, I see as paint texture so I let that be. --Cart (talk) 16:33, 29 March 2020 (UTC)[reply]

Neutral Sorry, I had no idea of how a Fresnel lens looked (english article and google image search) and I find that this picture doesn't help me picture it. And the base is very prominent compared to the lens itself. I can understand it may be hard to get a better point of view. - Benh (talk) 16:16, 29 March 2020 (UTC)[reply]

Support Not technically perfect but a very interesting photo. Cmao20 (talk) 18:24, 29 March 2020 (UTC)[reply]
Neutral: new version is a definite improvement, but the overexposed areas are still too distracting for me. --The Cosmonaut (talk) 19:08, 29 March 2020 (UTC)[reply]
