comment Normalize the brightness of images with different exposure times using EXIF data
@WayneF: thank you for your valuable input.

comment Normalize the brightness of images with different exposure times using EXIF data
@WayneF: I think you misunderstood the question. Without EXIF, there's no exact solution to the problem, only guesswork.

comment Normalize the brightness of images with different exposure times using EXIF data
@Olivier: yes, I meant shutter speed (don't like this term). I don't need to edit EXIF; I need to make two images with different exposure settings appear as if they were taken with the same settings; it can be easily achieved based on the EXIF info of these images. The exposure adjustment values in PS appear to be EV units, but I need a confirmation on that. I'm doing science; eyes aren't nearly good enough.

comment What's the relationship between chromatic aberration, ISO and long-exposure noise reduction?
Thanks for the link, great read for a photo-newbie like myself. I'm not convinced by your conclusion, though. The purple glow doesn't look like chroma noise to me. I wouldn't call it noise at all, as it doesn't seem to have the spatial nor the amplitude distribution of your typical thermal noise.

comment Why do breathtaking views turn into “boring” photos, and how can I do better?
@phresnel: Hm, you're right! I recall reading an article by famous soviet popularizer of science Yakov Perelman called "The art of viewing photos" (it doesn't seem like the article was ever translated to English). Perelman suggests that to achieve realistic perception of a photo you must view it the same way the camera did: with one eye, and from the distance equal to the camera's focal length. Since focal length distance is too small for most people but myopic, he then suggests using lenses to extend this distance while retaining the correct angle of perspective.

@StanRogers: Indeed. An image is called exactly that for a reason. Most of the time, a photographer's job is not to convey visual data, it's to convey impression. Which, in turn, is highly subjective.

@phresnel: I often don't recognize the difference either. The power of imagination (for the lack of better word).

@phresnel: that's obvious, but I was referring only to point-and-shoot systems (a single camera).

Speaking of eyes, stereophotography is a thing these days. It doesn't work for scenery as well as for close quarters shooting, but it still works.

Thanks. The problem is I didn't care much what FPS I get, but I expected the camera to shoot at this constant FPS at least in a wide range of settings, so the valuable conclusion is I can forget about that.

I have indeed had slow shutter speed, and of course I didn't even think of looking at it. I'm still not at 3.9, but at least over 3.1 now. ISO 200, I assume that's low enough. Thanks for the great checklist.
