  1. 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
  2. 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.
  3. 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
  4. 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
  5. 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
  6. 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
  7. 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
  8. 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
  9. It would be nice to have .fits file handling for astrophotography.
  10. Here are some of my fall exploits. Consist of Panoramas and impressions.

  11. Like GarryP said, nicely done. I like the drama you've created in each shot.
  12. PS: light pollution is a consideration, but there shouldn't be too much in that location to get good results. This was my first ever shot with my current setup, just down the road from my house at our little beach. My community is small so it's not like it's a big city, but there is still a lot of light pollution from this location: First Milky Way by Greg Murray, on Flickr
