HDR Sunset in Gothenburg

  •  Info Created, uploaded and nominated by Nattfodd --Nattfodd 23:05, 4 July 2007 (UTC)[reply]
  •  Support While a nice sunset by itself, this is nominated because it gives a good example of a HDR image, where multiple exposures and tone mapping are used to correctly expose every part of the image while retaining good contrast. --Nattfodd 23:05, 4 July 2007 (UTC)[reply]
  •  Support--Mbz1 23:15, 4 July 2007 (UTC)Mbz1[reply]
  •  Comment Impressive dynamics, but i have the feeling that this is extreme artificial, over&underexposed, oversaturated, overcontrasted and distorted in some way. This is something from merlins hat. Where is a reference? Plus there is a optical distortion when looking at the architecture on the sides --Makro Freak 02:56, 5 July 2007 (UTC)[reply]
    •  Info It's "normal" that it looks artificial, HDR images often do. Looking perfectly natural is not the point. Architecture distorsion is simply perspective when shooting at 11mm. I don't get what you want with the "reference".--Nattfodd 09:07, 5 July 2007 (UTC)[reply]
  •  OpposeNoisy, oversharpend, tilt and it looks too unnatural --Simonizer 07:13, 5 July 2007 (UTC)[reply]
    •  Info Noisy, maybe, though I shot 200 ISO and used a pretty heavy noise reduction filter in photoshop. I don't think it's a problem if you don't zoom to 100%. Oversharpened is impossible: I never sharpened it, and neither did the camera. Tilt is also impossible, I checked with the ruler at 100%, try it for yourself. As for unnatural, cf last comment.--Nattfodd 09:07, 5 July 2007 (UTC)[reply]
    • First of all. Please sign your comments. Secondly, with tilt i meant the distortion by the wide angle focal length that i dont find necessary for this picture. Maybe the oversharpend effect comes from too much contrast or oversaturation. But i can go on with the flaws of this picture if you like. There is fringing around the windows of the buildings and all the buildings in the middle and on the left side of the picture are overexposed. --Simonizer 09:01, 5 July 2007 (UTC)[reply]
  •  Oppose Overprocessed --MichaD | Michael Apel 14:46, 5 July 2007 (UTC)[reply]
  •  Oppose I have the hobby of HDR as well, but this pic is noisy and overexposed. Look at the histogram: you didn't take enough pictures, so you couldn't compress the dynamic range enough. Moreover, HDR-renderer algorithms are likely to increase noise, so, if you want to use some pics for HDR, you have to take them with the lowest possible ISO. Removing noise is not a solution, because Gaussian noise cannot be removed, unless you accept to loose some data (feature pictures must have no compromise!)

  •  Oppose Noise and distortion. --Digon3 talk 17:50, 5 July 2007 (UTC)[reply]
  •  Oppose Great sunset, but the picture is noisy and unsharp. --AdrF 22:40, 8 July 2007 (UTC)[reply]
result: 2 support, 5 oppose, 0 neutral => not featured. Simonizer 13:21, 14 July 2007 (UTC)[reply]
