  1. I'd like to request a hotkey option in blend range where pressing and holding the hotkey will give you a grey or red mask showing you exactly what areas are coming through/being affected. This would help it in being more exact and blend range would truly become the new luminosity masking. It's only limitation is that you can't physically see what EXACTLY you're affecting. I get the feeling that blend range wants to be a scalpel, but without this option, it's still a bludgeon. There are workarounds but if it were a hotkey option, it would be so smooth. Also, as I added in a different feature request, changing from master to Red, Green Or Blue should allow you to control not the colour, but the channel, or maybe put in a channel selector so you can choose the blend of say, a blur filter, to only affect the shadows of the red channel and nothing else. Currently if you adjust green and blue down so it is not affecting those pixels at all, it also still affects the red, and quite significantly at that. There is a workaround to that as well: creating grey-scale images of each of the channels and working on them individually and then rebuilding the colour image, but Blend Range is SO CLOSE to achieving this in one simple step.
  2. Hey, Sorry I don't ever get notifications about responses here and I have a hard time remembering to log in to check. It still does it even in the current version (and Beta) except I discovered that it only happens when I've done a large focus merge, a larger stack, or a panorama (of any size). To stop it from happening, I adjust what I need to, export it as a tiff and reopen the exported file, and then I can continue working normally with nothing ill occurring. I have to do the export as soon as is possible, if I work to the point where AP does this to me, I can no longer export the file and have to start from scratch; it only exports a black image when the bug takes hold. I will try turning off hardware acceleration, it's about the only thing I can try.
  3. Older request, but I also +1 this. Where it would be very useful is in reducing noise targeted to specific colour channels with both a NR filter and Guassian Blur filter. I figured it would work just switching to the different channels under master but it doesn't. Say for example I want to affect the red channel only with a blur, and the shadows at that. I create a guassian blur, turn on the red channel preview so I am ONLY seeing red, when I switch to green and blue in the blend range and remove the guassian blur from those channels, it clearly still affects the red and it's as if I never added the adjustment in the first place. Not at all how one would expect the blend range tool to work when working in only one channel: If you choose Red in the blend range, Red should be unaffected by adjusting the blue and green channels. There is a workaround but it takes a lot of time and effort to do: create greyscale representations of each colour channel, apply NR and blur to each one individually and then rebuild the colour, but blend range is SO CLOSE to doing this in one easy step.
  4. Hi there, So this error happened to me several times back in Beta 1.7 but since the release it hasn't done it till now so I figured it was solved. However, my copy is now doing the same thing it was before. When working on a bit larger files (this shot is 600x8500ish px, when I added things like levels and curves and then try and mask those with the erase brush form certain areas, it stops working and gives me a weird readout when resizing the brush. I've attached a video of the problem via dropbox. Thanks! Greg https://www.dropbox.com/s/bbhood09aikt6k6/Screen%20Recording%202019-07-25%20at%201.17.37%20PM.mov?dl=0
  5. I don't know if it's been asked, or if it is even possible, but it would be nice for the blend modes to follow the working profile of your file. Right now, if you're working in a CMYK file, the blend modes still behave as if they're RGB. In other words, 'Adding' CMY together turns the screen full white when it should be brown.
  6. These are some recent snowflake shots I got. Quite happy with them. Focus merged with anywhere between 6-13 images. FebSnowflke1 by Greg Murray, on Flickr FabeSnowflake2 by Greg Murray, on Flickr FebSnowflake3 by Greg Murray, on Flickr FebSnowflake10 by Greg Murray, on Flickr
  7. A little early but not sure if I'll get out to do anymore photo's this year. If I do and I like it a lot, I'll add a 'bakers dozen' to this collection. Here are 12 of my favourite images of this year. Story behind a few: the NASA bubble image isn't obviously mine, but I added it because of the sheer amount of experience gained from editing their raw data into the final image; something I was unsure I could even accomplish. The image of the stone fence and leaves was added because I accomplished the task of converting an old K10D to full spectrum, myself Also learned a lot with that project. Finally, the photo's of the girls; I finally feel I am getting to a point where I can photograph them and do it well enough to do justice to their beauty and cuteness. The rest are favourites for various reasons, if you're curious just ask. 2017DozenFaves by Greg Murray, on Flickr
  8. Here is another practice edit of some more Hubble telescope data. Learning! Affinity Photo handles this type of work supremely well! Very similar edit to my post about the Bubble Nebula except this time the Hubble team imaged Ha (Green), SII (Red) and OIII (Blue) instead of Ha, NII, and OIII as in the Bubble Nebula. It was also more difficult to get looking like their edit, and required me adding a layer of Blue Ha, selectively erasing it and lowering it's opacity, as well as adding a layer of green SII. I used FITS liberator to stretch and convert the FITS data to .tiff for each of the three filter tpes (2 times for each, one strong stretch to bring out faint details, one weak stretch to keep highlight details) edited the 2 sets individually, brought them together and used the blend range tool to blend the two. Selective denoise, and a little more colour work in LR. EagleMyEdit by Greg Murray, on Flickr
  9. Thanks folks! I really can't take credit for the photo, just the edit. BTW, I did get it looking a lot more like the NASA/Hubble Heritage folks did. Done by adding a layer of Hydrogen Alpha coloured blue. My brother and I think that they did this because the Ha is glowing at different temperatures inside the cloud. I have to say, Affinity Photo handles these edits wonderfully. BubbleFinal by Greg Murray, on Flickr
  10. So I found a free program developed by the ESA (European Space Agency) called FITS Liberator. It basically reads and stretches FITS data and saves it as .tiff files. I've also found some open source images from NASA's Hubble Telescope where they allow you to download their .fits files on some targets for education and experimentation purposes. I've been wanting to know how Affinity Photo would handle an edit like this because one day, I'd like to purchase my own astroimaging camera that can capture narrow band emissions, and so far I am liking the results. I do not however come close to the skill that went into the finished NASA image though so I have a lot of work to get to that point. The Images here for reference were taken in Hydrogen alpha (Ha), NII and OIII What was done: Bubble Nebula 3 sets of .fits data brought into FITS Liberator, stretched and saved as .tiff 2x (one minimal stretch to preserve highlights, one stronger stretch to bring out more nebulousness). I then brought these 6 into AP. I brought the 3 minimal stretches into their own window and the 3 stronger stretches into another window. I performed the following edits on each set individually: Selected all three layers, straightened them,and cropped the excess off. As they were all grayscale, I converted them to 16 bit RGB so I could manipulate the layers and create a Hubble false colour image. I then selected each layer individually and mapped it to a specific colour. This is done in the channels tab at the bottom underneath layers. You select the layer you want, scroll down to the bottom where it says: Pixel Red, Pixel Green, Pixel Blue, Pixel Alpha. To isolate a specific colour, you right click on which ones you don't want and press "clear". For example, for Hydrogen alpha I cleared pixel red and pixel blue, turning the layer green. For NII I cleared pixels green and blue, turning this layer red and for OIII I cleared pixels green and red, turning this layer blue. I then selected all three, went to the blend options and selected negation. Once this was done for both sets of the 3 images, I flattened them and copied the stronger stretched version and pasted it into the minimal stretched version. I then made sure they were aligned and used the Blend ranges tool to blend and restore the highlights. This kept the surrounding nebulosity visible but made sure the centre wasn't too white. I then flattened the image again and did some contrast/shadow adjustments, curves adjustment, clarity adjustment, and a tiny white balance adjustment. Flattened it again and exported out as a tiff and into LR for some more minor adjustments and storage. All this work, and I fell spectacularly short of the NASA edit, so I have a lot of learning yet to do. I've combined the source images, my finished edit and NASA's finished edit into one image for reference. Same data, so I should be able to get it close to NASA's version with more practice. I do have a feature request for AP to incorporate .fits files into their fold. BubbleNebulaHubbleData by Greg Murray, on Flickr BubbleLessonPoster by Greg Murray, on Flickr
  11. Here's two recent images i've done in AP from data i captured a week ago. OrionZS71 by Greg Murray, on Flickr FlameHorsehead by Greg Murray, on Flickr
  12. It would be nice to have .fits file handling for astrophotography.
  13. Here are some of my fall exploits. Consist of Panoramas and impressions.
