  1. This screen shot depicts a problem that I am experiencing with haze removal in Affinity Photo 1.7.1: Before haze removal the blue tone of the sky was uniform; after dehazing three distinct tones are visible. The parts of the sky that are visible between parts of the crane and immediately around it are lightest and closest to the original tone. Left and right of that area the sky has a saturated look. The blue tone in the right corner of the picture has an unnatural appearance. Unfortunately, I neglected to make a copy of the original Background pixel layer before dehazing. My questions about the haze removal in Affinity Photo concern the algorithm, and how I can help it to avoid mishandling the sky. I have other examples of this, e. g., two exhaust chimneys on a building in the foreground with the sky between them much lighter than the sky to the left and right after dehazing. What dehazing algorithm is Affinity Photo using? I suspect it is based on so-called dark channel priors. Such algorithms are known to struggle with expanses of sky. Various refinements to the basic algorithm have been proposed to mitigate the sky problem. I have accepted the default values suggested by the Haze Removal filter. I realize I can decrease the strength, but the differences in the sky tone remain unless the strength is decreased nearly to zero. When I develop my RAW photos in the Develop Persona of Affinity Photo I open them with Tone curve set to "Take no action" in the Develop Assistant, then I increase the RAW latitude by pushing the black point a bit to the right of the histogram (ca. 5%), pushing the midtones towards the middle by increasing the brightness, increasing or decreasing the exposure, shadows and highlights as required, and adding a bit of sharpening. Adding contrast, saturation, clarity, etc. and, importantly, a tone curve, I leave for the Photo Persona. I have the feeling that such a "flat" image might be creating problems for the dehazing algorithm, and I should perhaps either add a tone curve in the Develop Persona and dehaze the Background layer in the Photo Persona, or do that plus a Merge Visible in the Photo Persona and dehaze the pixel layer produced by Merge Visible. Comments or suggestions very welcome.
  2. I just bought AP for iPad an hour ago and already have a problem. On a raw photo from my Sont A7, when I try to do Haze Removal it says “analyzing” and just hangs there. I have to cancel the app. This is on an iPad Pro.
  3. I don't know if this is a bug since I'm using the filter unconventionally, but it seems odd. I'm finding the haze filter brilliant in function for those landscapes, but equally useful for clearing up all kinds of haze. When I used it on this street image where to hot Texas sun gave everything a hazing look, the filter didn't apply evenly. It's as if straight lines within the image confused its application and it didn't work consistently throughout the image. I tried it again as a test, and the straight lines through it off again so that it only applied within what it interpreted as specific quadrants. If you look at this sample image you'll notice that the area to the far left is clear of haze only up to the line of the street lighting post, then hazy above the truck, then haze cleared after the truck.
  4. After applying the remove haze filter, the other layer adjustment tools do not work. The dialogs open, the sliders move but there is no change to the photo.
  5. Hi, A friend of mine has the Macintosh version. He told me about a function called "Haze removal". Is that available in the Windows version? Rgs /EGW
  6. Hi, in diesem Affinity Photo Tutorial zeige ich aus der Serie Affinity Photo Foto Optimierung wie man das Foto Staffelhintergrund verbessern kann. Hier geht es nicht um große Effekte, sondern um viele kleine Verbesserungen, die dann hoffentlich für ein besseres Ergebnis sorgen. Es geht darum, eine Tiefe im Foto zu vermitteln. Durch Dunst in den Tälern. Außerdem war das Original diesig. Ein typisches Problem bei Landschaftsaufnahmen mit großem Teleobjektiv. Den Dunst gilt es, zunächst zu entfernen. In this Affinity Photo Tutorial, I show you from my serie photo optimization how to improve a photo. There are no great effects, but many details which hopefully improve the result. In this landscape photo, I show how to improve a background with haze and dust from valley to valley. Viel Spaß / have fun Ciao Jack Foto / photo: eigenes / self made YouTube-Video
  7. I'm trying Affinity Photo's (v1.4.2) Haze Removal filter on an Olympus E-M1 raw file (.ORF). The filter seems to have no effect (zero) at all, even though I realize I need to Develop the raw file before I can access the Haze tool. The raw file is recognized by Affinity Photo and opens just fine. But the Haze Removal tool doesn't shows no visible difference. (Note that Photoshop CC and its Dehaze effect works well and works directly on the raw file... no "development" required.) Maybe there's something simple I'm missing, even though I watched the video about this tool a few times and tried to research it's use here in the forum. Thanks for any advice you can give.
  8. hi i serch haze filters command in my affinity photo program but in the menu bar this command don't appear ! why?Please asap !
  9. I may be one of the the last to update a software.. yet, I watched the tutorial on haze removal before updating, before I updated. And I can not seen to find the "Haze Removal" under the filter tab. Geez, (Silly me) I apologize. I'm uploading to Aperture on my Mac Book Pro (giggles, a lot of pro and needed more book!).
