Shell of a Rock snail, Coralliophila costularis
  • Thanks for your reply. What would you suggest I use as an optimal guide to calibrating brightness on my screen? It's precisely at greater resolutions that I get the whites running together; at lower resolutions, the shell seems separated into sections naturally. -- Ikan Kekek (talk) 11:03, 28 June 2019 (UTC)[reply]
  • Ikan Kekek The en:Wikipedia:Featured picture candidates has some calibration guide for whites/blacks, though I'm not sure how scientific or up-to-date it is. I wouldn't expect to see more than the three circles on that page on a laptop screen. In terms of "blown areas" this doesn't necessarily translate to pure white on a JPG or monitor if the photographer has lowered the exposure (or highlights) in a raw processor. What matters more is whether there is loss of detail or lack of smooth tonal graduation, and sometimes that can also be hard to distinguish from the area merely being out-of-focus or smooth and lacking detail anyway. Some displays have a variable dynamic range where it alters the brightness of the backlight depending on the average brightness of the scene. Usually that mode is more appropriate for watching movies than computer use or viewing still photos. You could check what mode your screen is in, if that can be adjusted. Many computer screens are set too bright by default. Also if you have a bright window behind your screen, then your eye will be less able to see a full brightness range than if you faced a wall or were using the computer in the evening with lights on. Make sure you have the screen angled to point directly at your eyes, since viewing most LCD displays off-angle results in a loss of contrast. -- Colin (talk) 11:41, 28 June 2019 (UTC)[reply]
  •  Comment - I'm not sure what to do. I can see only one of the gray circles - the one furthest to the right - no matter how bright I make my screen. I'm not sure how to adjust contrast. I'll investigate further. -- Ikan Kekek (talk) 12:19, 28 June 2019 (UTC)[reply]
  • This seems to be a known problem with Windows 8.1. Now I really don't know what to do, except when it's not super-obvious, to ask whether something is or is not blown or whether the whites run together or not. I can adjust the brightness at will, though. -- Ikan Kekek (talk) 12:26, 28 June 2019 (UTC)[reply]
