  1. BW Images still open as colour, and when manually converted to BW, they lose all their Foveon benefits. There's two methods to obtain BWs from Foveon RAWs, and neither of them work in AP. Images taken with the Merrill series cameras are normally able to deliver BW images without the mushiness of a CFA (colour filter array, such as Bayer), or the heavy resolution loss from an antialias filter, like with the a Leica Monokrom, yet are not prone to strong aliasing artifacts like many other cameras. All test images were captured in BW, latest camera firmware, and open properly in some other applications as BW (however, some LibRaw demosaic engine apps open them as colour, suggesting LibRaw as a possible element for the problem. Note however, that digiKam which uses LibRaw 1.19 builds these image thumbnails correctly in BW, and it is configured not to extract the embedded jpeg - it is building a downsampled version of the raw). Forcing BW RAWs to convert from colour to BW in Affinity Photo for the nearly 9 months of production and beta AP versions results in severely downgraded noise and detail and tonal range. How can I support Affinity support getting the issue posted to LibRAW's devs, so that it gets added into their mix of stuff 'in the queue' to be prioritized? I'd really prefer if it had the gravity of a respected LibRaw integrator (Affinity) verifying that it's not some lone user that hasn't done any due diligence. As well, the LibRAW folks might not otherwise appreciate that this affects all Merrill sensor Foveons (not all Sigma cameras, but a large percentage of the current user base).
  2. In Publish, Is there a way to convert select pages of a color document into greyscale?
  3. BW Images still open as colour, and even if manually converted to BW, they lose all the Foveon benefits. There's two methods to obtain BWs from Foveon RAWs, and neither of them work. Images taken with 1:1:1 Foveons (such as those with the Merrill series sensors) are normally able to deliver BW images without the mushiness of a CFA (colour filter array, such as Bayer), or the heavy resolution loss from an antialias filter, like a Leica Monokrom, yet are not prone to strong aliasing artifacts like other cameras. All test images were captured in BW, latest firmware, and open properly in many other applications as BW (however, some LibRaw demosaic engine apps open as colour, suggesting a possible source for the problem, for someone within Appian to register this bug to the LibRaw community). Forcing BW RAWs to convert from colour to BW in Affinity Photo for the last 8 months (all production and beta versions) results in severely downgraded noise and detail and tonal range. Thx.
  4. Members 12 59 posts BW Images still open as colour, and even if converted to BW in AP, it loses all the Foveon benefits (not very usable). There's two ways to obtain BWs from Foveon RAWs, and neither works. This has been occurring for six months of production and beta releases, and is not a newly reported issue.
  5. BW Images still open as colour, and even if converted to BW, lose all the Foveon benefits. There's two ways to obtain BWs from Foveon RAWs, and neither works. Similar crops below from the same image, all at 200% zoom (slight variations in cropping). Most recent of multiple posts (prior beta) Above: AP 1.7.2.414 choosing BW Above: AP 1.7.2.414 choosing BW and only using blue channel Above: IrfanView 4.5.2 as opened (uses DCRaw) Above: Sigma Photo 6.6.1 Export using Blue Channel only
  6. Resolved: Can confirm 1.7.1.404RC2 has full control over noise removal, especially chroma noise (working since recent betas: thank you so much), and is fully usable now on Sigma Merrill cameras. Also, only as of 404RC2 is EXIF and focus reliably consistent. Outstanding: BW images still open as colour: no benefits from in-camera BW captured images. Additionally, some BW images shot at higher than base ISO open like linear exposure (super dark). Quick test images (apologies for quality): 6745, ISO100, BW: in 1.7.1.367 and .404RC2 has EXIF and focus info, but recent prior betas were partially missing EXIF & focus metadata. In all versions, these open as colour (should be BW). 6742, ISO800, BW: Very difficult trying to extract a workable image from these RAWs (shot higher than base ISO). Opens fine in other RAW editors. Why Not Use Normal Colour to BW (Post-processing Conversion): The key issue behind this is that the Foveon Merrill can capture the full spectrum at every single 'pixel' (photosite), and output it in BW (like a Leica M Monochrom). No demosaicing is required (or ever wanted). When these are shot as BW in the camera, Affinity Photo opens them as normal colour images, and loses all their benefits. For instance, Foveons also normally capture full spectrum at every 'pixel', and when all treated as BW, you can get 3 times as much sampling per pixel as the monochrome Leica, for improved noise.

  7. Hello! First to introduce me: I´m a professional photographer for 35 years, with experience in many cases of professional photography, developing b&w, color negative, color positive processes, digital photography from its beginning, colormanagement. Meanwhile I work in a public photo archive with 100.000´s of photos from historical until now. About 90% are b&w photos. Digitalization of these photos and managing them in a DAM is my main work here. Right now I try to get a workflow with applications out of Adobe. But there seems to be a bug on the interface between CaptureOne and Affinity Photo. In CaptureOne 10 I export a b&w-file with embedded profile Gray Gamma 2.2. In Affinity Photo (V1.6.5.123) the settings for colormanagement is Gray Gamma 2.2 for b&w-files. When I open the exportet b&w-TIFF with embedded Profile, AP opens it in the Develpo Persona, shows the file extremely bright an assigns the profile for RGB to the photo because AP couldn´t recognize any embedded profile. I can´t rescue the file by assinig other profiles or by developing the file to what it should look like. If I open the same file in Photoshop with the same colormangement-settings, the file will be opened correctly without any profile-warnings. If I "save under..." this file without any changes, but with a new name in Photoshop and open this in AP, it will be opened correctly with the right profile an the right brightness. Any hints for wrong settings or steps in my workflow? Greetings Mikelike
  8. I've been scanning my old 35mm negatives with a Minolta Minolta Dimage Scan Dual IV so that I can put them up on my website. The negatives and all black and white and in need of a bit of attention, so my plan was to run them all through Affinity Photo to remove any dust and scratches and tweak the levels. I did this a few years ago with an old copy of Photoshop CS2 with no issues, so assumed the latest version of Affinity Photo should have no trouble. As I did the last time I scanned a batch of negatives, I have been scanning them with Vuescan as 16bit greyscale TIFF files. When I open the resulting TIFFs in Affinity Photo however, they are opened in the Develop persona with the picture completely blown out. On some occasions they fail to open at all and leave either a blank window reading 0x0 pixels, or crash the app completely. I'm happy to provide a copy of the error log if you think that would be helpful. I can kind of fix the blown out image (for the ones that do actually open) but it really shouldn't be necessary. The files which fail to open at all open fine in Preview, Photoshop CS2 and pretty much anything else I try to open them in. As it is, I am getting better results out of the almost 15 year old Photoshop CS2 than I am out of Affinity Photo. I know I could just use Photoshop, but my copy won't run on my current Mac so I have to open my TIFF files on an old Windows 7 machine. I would much rather however use Affinity Photo as I otherwise find it works very well for my needs. Is there any way in which I can open these TIFF files normally in the photo persona? Is this a bug or the intended behaviour for 16 bit TIFF files? Any help would be much appreciated. Thanks
  9. I use VueScan to scan lots of black-and-white images. Within VueScan, I set the input as B/W and the output to 1-bit Tiff. After saving the image, it automatically opens in Affinity Photo with the message that the default profile is automatically being applied. This means I get an 8-bit RGB image. Now I know that Affinity does not (yet?) support 1-bit images, but it is annoying to have to set the image to Greyscale every time. I tried to look up this Colour Profiling, but it seems that it is a global setup that will affect any unprofiled images that it loads. VueScan says that the saved tiff file will be 'profiled' whatever that means. I find that Corel Photo-Paint does not do this. It loads the tiff as a 1-bit image. Is it possible to prevent this happening? If I am about to scan a batch of black-and-white images, would it be possible to prevent this default profile being applied? I posted a similar query to VueScan support and got the following reply from Ed Hamrick: Profiles only work for scans that are in color. They don't make any sense for 1 bit per pixel, so I don't store a profile. John
  10. One feature missing from Affinity Photo is the ability to handle One-bit, or black-and-white images. I do a fair amount of scanning black-and-white documents, making small edits (typically cleaning up) and then saving them. I typically use Vuescan which will scan my documents and save them as 1-bit black-and-white tiff documents. I can open these in PS CS5 or in Paintshop Pro, and they open as 1-bit documents. If I open these tiffs in AP, they open as 8-bit RGB! Not even as Greyscale. I would expect that the histogram should show just black and white pixels, such as in this histogram (from Curves): However, what it shows is a histogram like this (also from Curves): Affinity has clearly found a range of pixels (in a 1-bit image) with intermediate values. I can apply a threshold in the Curves Adjustment at 127, which does indeed give me the histogram as seen in my first image. Can anyone explain this phenomenon? John
  11. I once saw a very good Affinity Photo video on how to apply a colour to a greyscale tiff. I need to review this but cannot locate it although searching through the official list. Anyone know where I can find it or the link to it?
  12. The screen shot shows a roughly created height map in Affinity Designer's Pixel Persona[] using the Paint Brush tool[] and using grey scale values[] and how it is used in generating a 3D Terrain in Blender by applying this height map Image as a 'Displace'[] modifier on a Grid []Mesh Surface. For smoothness, i have applied a 'Subdivision Surface'[] modifier. Modifiers in 3D Modelling tools help modify an object's geometry. They can be accessed in the Tabs on the right side[] and have a 'wrench icon'[] . Just click the 'Add Modifier'[] dropdown to add the modifiers mentioned above. Notice, if you apply these modifiers by clicking the 'apply' button it will apply the effect and remove the modifier from stack of modifiers applied. If you want fine tune control over these without removing them from the stack of modifiers,don't apply them.

  13. I have an unprofiled grayscale image that AP insists on opening in RGB color space, not Grayscale. The Color Profiles section of Preferences has different scenarios for assigning profiles, but is there a way to open an unprofiled grayscale file in Grayscale color space? Photoshop opens unprofiled grayscale files in grayscale color space as expected, why can't AP? I opened said file in PS, re-saved it as grayscale with Gray Gamma 2.2 profile, AP now opens it in Grayscale color space with Greyscale D50 profile. But what about AP opening it in Grayscale with the Greyscale D50 profile from the get go?
  14. Hi All, Anyone knows what is a good method to convert color images to greyscale non-destructively? Except the Black & White feature. I'm working on a school yearbook, most of the images is groups of children, class group images and sport group images. Thank you.
  15. Hi, it is possible to Import a Mask from a greyscale picture? Thanks

    Adding colour

    Is it possible in Affinity for iPad to add colour to a greyscale image. If so how do you do it? If anyone needs any more info just ask. First post!
  17. I am getting an inverse grey channel of the selected channel I choose from an image, this works fine in RGB though.
  18. In the beta version I could save images in greyscale. Now that I have purchased the full version I can no longer save images in greyscale. I can change the color format to greyscale and export it as a jpeg but it is exported in an RGB profile. How can I save it as a jpeg file in a greyscale profile?
  19. Hey! This is my first upload here, I just wanted to share a grayscale illustration of the beautiful skater Leticia Bufoni. 100% made in Affinity Designer, awesome software! I hope you like it! :D
  20. A feature I often use in Adobe apps is the Proof Setup option. In InDesign this allows me to check how document colours will look across different print and screen colour profiles, including some greyscale profiles. In Illustrator and Photoshop this menu option also checks how document colours would appear to someone with Protanopia or Deuteranopia-type colourblindness (for some reason this feature isn’t in InDesign). The colour profile previewing is nice to have, but I usually focus on just using the greyscale profiles as a way to test contrast in my artwork colours, and in Illustrator I often like to check that I’m not using colours that wouldn’t read well for a colourblind person. I’d love for Affinity apps to include greyscale and colourblindness preview options, as well as any other preview modes for visual impairments that may be useful. Having the ability to proof specific colour profiles would also be useful.

    Personal Logo

    I've made two variations of the same logo using only my first and last initial. I'm looking for some feedback on which catches the eye better. P.S. Can someone tell me how to make a perfect equilateral triangle?
