  1. Try this macro, if it works you can use it in a New Batch Job for many files Recolour0-100-0.afmacro
  2. No it's from a different lens, the 35mm F1.2 DG DN | Art 019, I just took a flyer to see what would happen. I think it's better than no correction and in some cases may be ok but it isn't suitable for architectural shots. What you need doesn't yet exist in lensfun
  3. Yes, that's my conclusion. This is one for the folk in Nottingham to fix
  4. Life's too short for that, I use Photolab which has superb lens distortion corrections plus Viewpoint which allows additional perspective correction. Anyone interested in such corrections would be advised to try the trials. The lcp comes from Adobe and was installed with the DNG converter. I think it's likely that Photo doesn't implement the lcp correction properly. I don't have any software that uses lcp's other than Photo but I would be amazed that Adobe would produce something that makes the issue worse eg in the image below the lcp version looks more barrelled than the uncorrected one to my eyes
  5. Looking at the lcp and lensfun corrections the former still shows a fair bit of barrelling and is basically useless
  6. If you open the lcp file in a text editor you will see this a few lines down from the top stCamera:LensPrettyName="SIGMA 35mm F1.4 DG DN A021" Replace all instances of SIGMA 35mm F1.4 DG DN A021 with 35mm F1.4 DG DN | Art 021 so they read stCamera:LensPrettyName="35mm F1.4 DG DN | Art 021" the lens will then be automagically recognised by Photo. I'd post the lcp but think they may be subject to Adobe copyright
  7. I never liked XP1/2, much preferred FP3/4, HPS, Tri X generally developed in ID11. I dumped all of my darkroom stuff except the enlarger which is a pre-war Focomat and a thing of beauty Anyway, back to the scan, as a confirmed Luddite I check the channels on scans and choose the one with best contrast, in this case the red Then create a greyscale layer and apply a curve adjustment
  8. From Help "Preferences Preferences comprise a series of miscellaneous options that are applied across your application. They can be used to set up your own way of working. General options <snip> For automatic RAW lens correction, include lens profile updates for new cameras. Place the downloaded Lensfun XML file or Adobe Lens Correction Profile (LCP) in the opened folder."
  9. I suggest you try both, lcp files can be used with Photo. Whenever I have compared them in the past the lensfun profiles came out better although it's subtle. Good luck
  10. You can do this the proper way per Alfred's link or you can cheat and borrow a similar profile Try attached xml in the Lens Profiles Folder - see Help if you're unfamiliar with this. I see a reduction in barrel distortion, comments in xml show what I did Sigma35mmf1-4dgdnFaux.xml
  11. I would suggest updating the graphics driver first as it's free. I don't have any Affinity results to share but using PhotoLab v7.2.0 to export 42 images 5134x3888 down to 600 high took 2h 1m 20s with the old driver, it now takes 0h 28m 25s Just created an image in V1 per your numbers 7086 x 10629, 32bit ROMM RGB and the performance is fine using paintbrush, clone stamp, smudge, erase brush 1000px diameter, this is a pretty mediocre spec pc as you can see below
  12. Here's a pdf exported from Inkscape 1.3 (0e150ed6c4, 2023-07-21), seems to open ok in Publisher V1 Breadcrumbs2-ink.pdf
  13. Resizing canvas is a pita in a macro. Transforms are hopeless, Duplicate and Equations are useful but although equations can increase an object's size it will be clipped by the canvas so that needs to be increased first. You can use John's advice to resize to a large number but here is another way. If you duplicate a pixel layer rotate 90° around its centre unclip canvas you will generate a square canvas Then use a fill layer rasterise rotate 45° unclip canvas you will generate a canvas increased by a bit less than x root2 so it's greater than your 20% (Do that step again and the canvas will be almost double the original etc.) The attached macro does this but I'm a bit foxed. The resized fill layer will have partial transparent pixels at the edges I tried a procedural texture of =ROUND(A/255)*255 for the Alpha but that failed I tried applying a curves layer to boost the alpha and that worked a couple of times but fails in the macro So, you can resize, for example, an 800x600 image to either 958 (x1.1975) or 962 (x1.2025) wide, I can't get it to be exactly x1.2 ResizeCanvas120pc.afmacro
