An almost night view of the Acropolis of Athens

✓ Done cropped No raw for this set (and only) - Merphy's law :P --C messier (talk) 17:37, 25 March 2015 (UTC)[reply]

  •  Oppose Looks very washed out as after too much highlight or shadow recovery. Some areas of the subject show almost no significant brightness changes. — Julian H. 20:30, 25 March 2015 (UTC)[reply]
  •  Oppose Too big dynamic range to adequately capture with only one frame. Too dark foregorund and too many burned highlights. The illumination appers more white than what I can find from a Google image search for illuminated night shots. Also it is a bit too soft for my taste and there is a little fringing. For such a subject, shoot raw, try to combine several bracketed exposures to better catch the extreme dynamic range. -- Slaunger (talk) 21:03, 25 March 2015 (UTC)[reply]
    •  Comment It's actually four frames merged into one. And it has more DR than most of the other images in the category, with much less blown highlights. --C messier (talk) 21:10, 25 March 2015 (UTC)[reply]
      •  Comment That information is worth adding to the file page, which has an exif indicating it is a single 6 s exposure. It is surprising that the end result does not exhibit a larger dynamic range when that is the case. May I ask how you have combined the exposures and how large the EV difference was? Do you still have the source images? It is my experience that you need a separation of 2 EV for four exposures with my entry level and not terribly new DSLR. There may be another optimum for your camera, which I am not familiar with.-- Slaunger (talk) 21:22, 25 March 2015 (UTC)[reply]
      • Combined as descripted here (although the brightest was the base, because otherwise, the stars appear blacker than the sky), it 6s, 2,5s, 1/1,3s and 1/5s with same f, ISO and exposure compasation, and I have kept the original images.--C messier (talk) 21:29, 25 March 2015 (UTC)[reply]
        • @C messier: Thanks for the information. If my math is correct that corresponds to steps of around 1.2 EV, 1.7 EV and 1.95 EV, which is a slightly odd spread of the exposures, especially the span from 2.5s to 6 s is a little low (1.2 EV), but it should be fairly OK, I guess. I do not know how well the GIMP method described works as compared to other methods. If you are interested in sharing your source images I could try and have a go at it using PTGui to make a 32 bit floating point "super raw" tif and postprocess that in lightroom as an alternative. -- Slaunger (talk) 21:41, 25 March 2015 (UTC)[reply]
        • @Slaunger: Were can I upload them? They are useless on their own to upload here. And if you can align the pictures, I have also a nearly identical set of exposures, but with raw with 6w, 1,6s and 1/4s. --C messier (talk) 21:47, 25 March 2015 (UTC)[reply]
  •  Oppose Sorry, the dark grey light-polluted sky isn't good. Prefer your one with blue sky but neither are sharp enough for FP. -- Colin (talk) 19:34, 27 March 2015 (UTC)[reply]
