  • I think there's something going on in that 500px are rebuilding or caching things behind the scenes. This image of mine that I checked yesterday: https://500px.com/photo/223017929/alterworld-walker ...
  • I'll look around more (I do use 500px, but I do not use Chrome). Maybe it's to do with upload date and whatever color-space logic they had running when the image was first uploaded. This recent one ...
  • The image here: https://drscdn.500px.org/photo/176011731/q%3D80_m%3D2000/v2 has no embedded color-space, but carries an sRGB tag. It looks fine for me in Safari on OS X, but more saturated in ...
  • This command removes all metadata. That includes the color-profile. Probably because the original image is in Adobe RGB (or another wider-gamut space), so the color numbers are Adobe RGB and ...
  • Adobe release notes 6.6.1 (25 July 2016): https://blogs.adobe.com/lightroomjournal/category/general Adobe release notes 6.12 (18 July 2017): http://blogs.adobe.com/lightroomjournal/2017/07/lightroo ...
  • They take up space, but nowhere near as much compared to an RGB pixel-data layer. A layer mask (in a 16-bit image) is a 16-bit grayscale, so it's max 1/3rd the size of the pixel layer ...
  • The maths sounds about right. 36MP from your D810 x 3-channels (R, G, B) x 2-bytes per channel per pixel. That equals 216MB of pixel data per image layer. Add a duplicate layer, and then you also ...
  • Indeed you can (with CC 2017). Not sure when it was introduced (I think CC 2014). There's an entire workflow with smart objects and embedded linked files which enables non-destructive: https://help ...
  • Replied in PSD vs TIF
    Which is not what you said, but nevemind. That''s my last word thanks; no need discuss more.
  • Replied in PSD vs TIF
    Yes I know - that was exactly what I wrote and the whole point of my post.
  • I got as far as this..... Name is Meng Fan Chao, studio is Mitang Impression: http://contest.asiawpa.com//member_award_details.php?id=373 http://www.photoserve.com/search_results.php?category_id=&o ...
  • Can you tell us the name of the artist and then we can go and find original files ourselves.
  • Replied in PSD vs TIF
    What (or who) is the "they" you mean??
  • My guess would be hand masking of curves layers (or levels) just to pick out areas of leaves - i.e. could well also just be precise localised hand dodge and burn. As someone else has said could be ...
  • Replied in PSD vs TIF
    It's not mentioned in responses above, but psd maxes out at 2GB and TIFF at 4GB - i.e. if your work gets over 4GB, you need be in Adobe PS format anyways. I do composites in 16-bit and often end ...
  • I was just highlighting that there are different ways to do put noise jitter in. Clipped adjustment or pixel layers are one way. Destructive noise/blur filtering of a rasterised colored gradiented ...
  • Your problem really feels like display path - as Digidog is telling you. I get the same in PS (particularly in very subtle B&W gradients), and yes - it's all but disappeared from the image when I ...
  • Technically exactly no, not for all Nik filters as the Nik Collection are also algorithmic (meaning adjacent and surrounding pixel computation). It would need be a complex combination of ...
  • Which is good news in this context, because Google's Snapseed (which is a lot of Nik) and also Serif's Affinity Photo are available as iOS products (this was the point I was really making). So, ...
  • The most recent versions of the Google Nik Collection are flagging as 64-bit apps on my system using same method to view as Thom Hogan is: The V1.2.11 installer also shows as 64-bit (I looked at ...
