  1. Hello, I recently took images of the night sky and my camera has quite a lot of Hot Pixels when doing a long exposure. I recorded Dark Frames with the exact same settings and I want to know: How do I process them? Is there a way to efficiently remove hotpixels? Does anyone have advice in general? Felix
  2. Hi everyone I have recently expanded my photographic hobby into astrophotography. Some time ago I watched a tutorial on the stacking feature in Affinity and thought I would give it a crack with some images I've taken in the last three or four weeks. I have to say that I am very happy with the the very first images I took and ran through Affinity. The process is somewhat quicker than dedicated stacking programs for astro but the results (for me) are very very satisfying. I thought that perhaps those that are interested could post their images and discuss different processing techniques that they have used. So I guess I'll get the ball rolling with my first astro edited with Affinity Clear skies D

    astronomy photos

    I am still learning my way through AP and have started re-working some of my old images which are now much improved vs my old editing techniques in PS Here is my 1st main attempt using AP This is IC5070 Pelican nebula in Cygnus tone mapped using Sii as Red, Ha as green and Oiii as Blue. 9x5min each colour channel. Stacked and aligned in Astroart, Initial stretching and development in Startools then colour re-combination, balancing, additional tone mapping and sharpening in AP. BTW - AP did these final stages in a fraction of the time PS takes. Clear Skies

    Astronomy macros

    Now that I have made the switch to AP I am re-working many of my astrophotography macros. I will share them here with brief instructions and encourage others to share theirs. All my macros are for Windows OS This set of 3 takes the basic individual monochrome filtered R G and B images and converts each into a colour channel. Load each RGB file separately into AP, Run the respective macro and copy the output of each into a single AP layered document, then set the blend mode of each to add This will output a single RGB non white balanced file grey to blue.afmacro grey to green.afmacro grey to red.afmacro
  7. I have been doing some processing of astrophotography data. These files usually originate as FITS files which are the raw data files from the telescopes. I process the files using Liberator 3 which then saves the FITS files as TIF files (8, 16, or 32 bit). When I open the saved TIF files in Photo they have large rows switched around or have data that is off the page and missing. When I open the same TIF file in Photoshop the files appear normal. I can then re-save the TIF files out of Photoshop and then Photo opens them correctly. This is on Photo running on Windows 10. Here is a sample TIF file that was saved out of Liberator. When I open this specific file in Photo the image is moved up off the document area and the top part is missing. I can post screen grabs of the errors if other people are not getting the same thing when opening this file. Thanks for any assistance! http://www.spacetelescope.org/projects/fits_liberator/ The file is an image of the Eagle Nebulae if anyone was wondering. 502nmos.zip
  8. Unless I'm missing something on Vimeo, I haven't seen anything from Affinity on developing milky way photos, which I assume is kind of a common task. It's also something I'm terrible at so far, both with Affinity and Rawtherapee. So I'd love to see an official video, or even a series on developing milky way shots to bring out the color, and developing astro photos in general.
  9. Hi All, I'm new to astrophotography and to Affinity Photo. I'm currently using the 10day trial but so far have been impressed by the software. I am experimenting with stacking multiple photos. I am using the Starry Landscape Stacker which seems to only use .tif files. I need to convert my RAW exposures to .tif before I can upload them to the program. The output file is also .tif. The output image is beautifully stacked - the stars are pinpoint and any noise largely reduced. My problem is this: I would like to upload the output image to Affinity Photo, but when I open it the image appears scrambled and off colour, a complete mess really. When I open it in Photoshop, it is as I expect it and also when i open it in Quick View on Finder. The problem seems to be with Affinity Photo? As I am new to this type of photography and to Affinity Photo I would like to check if there is something I am doing incorrectly. I explored trying to save the final image in Starry Landscape Stacker in a different format, but it seems that it only saves it as a .tif. Any help/advice would be greatly appreciated. Or is there another free stacking app I could use? I attach screenshots of what the same image comes out in Photoshop and in Affinity Photo. Thanks Very Much Soul
  10. Hi, I saw this thread in the forum regarding a problem with Affinity reading TIFF files generated with FitsLiberator. https://forum.affinity.serif.com/index.php?/topic/36672-photo-does-not-open-tif-files-saved-from-fits-files-correctly/?hl=%2Bfits+%2Bliberator I have this same problem. The problem does not occur when I try to open the files in applications like Pixelmator. In the thread there was an indication that the development team would look into this issue. Are there any developments on this? I bought an Affinity Photo license in December to use it for astrophotography but am stuck with this problem ever since... Thank you for your time, Luis Lopes
  11. Hey again, it's been ages since I actually shared some of my work in this forum. Over the course of getting imagery for the tutorials, I've also produced some final pieces that I'm happy with. Recently I've been tackling tutorials for astrophotography/star image editing as well as light painting, so there have been a few late nights! My favourite so far is a light painting composite near my home: Rail Tracks by James Ritson, on Flickr Then a light painting of Rufford Abbey (although I think I narrowly avoided a run-in with security): Rufford Abbey by James Ritson, on Flickr Followed by another light painting composite underneath an old railway bridge. This one's a little scrappy and I'm not sure how I feel about it at the moment: Under The Bridge 01 by James Ritson, on Flickr Moving on, a combination of star photography and light painting at Rufford Lake: Rufford Lake 01 by James Ritson, on Flickr And then a shot of the night sky, which was achieved by stacking 50 images (shot at ISO 6400, 1s long each) and pushing the tones quite severely to produce a vibrant result: Still Sky 01 by James Ritson, on Flickr That's about it for now - some of the above imagery is used in the recent tutorials and I plan to hopefully produce some more videos in the future covering these areas of photography. There are a few more images on my 500px and Flickr accounts as well if you're interested! Thanks, James
  12. Hi, I came across a nice tutorial for post-processing Nothern Lights/Star photography using Photoshop On FStoppers (https://fstoppers.com/originals/advanced-six-step-program-processing-aurora-lightroom-and-photoshop-164984), and I was particularly interested in section 5 of this tutorial which aims at making "leading stars" bigger using luminosity masks. I have tried doing something similar in Affinity Photo using Blend Range tool (equivalent of luminosity mask in Affinity Photo) but I have not been successful. Using an unsharp mask filter and a lighten blend mode makes all the stars a little bit bigger (which is a good start) but I am after a more dramatic effect that only works on the biggest stars of the image (without going through the painful process of manually enhancing them one by one using local adjustments). Would someone be able to give me some pointers on how to achieve that? Thanks, Xav

    AP - Orion

    Hi all, I'm quite new to this whole photography thing... I'm really interested in nighttime photography, experimenting with different exposure lengths etc. and I had a go at shooting star constellations, in this case Orion. I just want some honest (not too honest!) feedback about the photo. it's a single shot, so appreciate there is a lot of noise in it. On AP, I played around with the exposure levels, temperature, contrast. Thank you Soul
  14. It's been a long, long time since I posted anything. :huh: I saw a program on the two eccentric artists on the box, so armed with two photographs that I've take on my Fuji bridge camera, I decided to give it a bash... The girl in question was my ex-stepdaughter; who strangely didn't like this shot of her by the beach. :huh: All comments welcome... SaveSave a little bit of G&G.afdesign
  15. Can you please post a beginning-to-end video of the various processes for developing/editing a RAW photo of the milky way? There are many photoshop instructional tutorials for this process, but I can find none for Affinity Photo. I much prefer to use Affinity, and I'm still somewhat inexperienced with photo editing in general. I want to invest my time in learning Affinity directly, rather than learning photoshop and then translating that experience to Affinity. Thank you for your help. I am attaching a amazon cloud link (the file is too large to upload here, 27MB) to a RAW file for you to use in a tutorial, should you agree to help. I voluntarily relinquish all rights to the linked photo. It is now public domain. https://www.amazon.com/clouddrive/share/ELVNzIxUzNWFk1twdvVOaHCkD0xWV24wuMhGgUGldRR?ref_=cd_ph_share_link_copy Thank you James
  16. I'm thinking of stacking several astrophotos with foregrounds and to do it I'll guess I will need to mask the foreground to get clean and sharp stars. Is it possible to do one mask in one layer and then copy it to all of the other layers?
  17. Hi all, I' reasonably new to imageprocessing, but have gained a little experience in Nebulosity and GIMP for creating and retouching astrophotography images. In astrophotography you typically and up with 4 separate greyscale images; one for each RGB channel and one for luminosity. To create an RGB images in Nebulosity you select the function "composite RGB", assign the right greyscale image to the right channel and press "apply"... and there it is :-) I've been trying this in Affinity, but can not find/comprehend a way to do this. Can anyone point me out were to start and how to accomplish this? Thanks! Johan
  18. Hello, In doing astrophotography, these two features are really essential. I really love using AP for editing, but it becomes nearly impossible to with astrophotography because it's missing these two features. Especially because AP has features like LAB, it could be a really great tool potentially - and I don't think (at least the median mode) is very difficult to implement. They're useful for stacking photos - when taking pictures of the night sky without a tracker, you're limited in the exposure length you can use, because the Earth is rotating. To get a useful picture, you really need an exposure with at least ISO 3200, making very noisy images. The solution is to take multiple pictures and align them in post, and then use a median filter to remove the noise (which is incredibly effective). It's useful for other things as well - basically any noise reduction. There are perfectly clear stacks of images taken at ISO 25,600 or higher - and the median filter can get rid of people walking in front of a landscape, for example. My point is, these are really useful features for everyone and could add a lot to the abilities of AP and make it a very appealing software for another group of photographers.
  19. Will Affinity Photo stack images? A typical shot for me is between 30 and 60 images. I'm using a Canon 5Ds and macro lens. Thanks, James
