Greetings all from Malta! Just dropping in to say I've put live three new videos and added them to the first post. They are Retouching, iOS 11 Drag & Drop and On-Screen Modifiers, and here they are for easy access: Retouching (Frequency Separation & Retouching Tools) Discover Photo for iPad's range of retouching tools, including: Automated Frequency Separation Blemish Removal Tool Healing Brush Tool Patch Tool Clone Tool Inpainting Tool Watch: Vimeo / YouTube iOS 11 Drag & Drop See how to use iOS 11's new Files browser and its drag-drop functionality to import images into Photo - including dropping multiple images in for stacking, HDR merge, panorama stitching and more. Watch: Vimeo / YouTube On-Screen Modifiers Learn how to enable and use on-screen modifiers with the iPad version of Affinity Photo. They behave the same way as traditional modifiers (Ctrl, CMD, Alt) but are touch-based. Watch: Vimeo / YouTube Since I recorded the iOS 11 Drag & Drop video, I'm aware that the developers have added several cool drag-drop additions, so once I return next week from holiday I'll look into re-recording the video and keep you updated when it's ready. Hope you find the videos useful!

Hey Ian, the best way to achieve this is to: Use a Channel Mixer, Curves or Levels adjustment (depending on how you want to blend). On these adjustments, you can set the colour model to CMYK or LAB if you're working in RGB (and vice versa). So you could add a Curves adjustment, switch to LAB, then tweak the Lightness curve. This method is completely non-destructive. Alternatively, if you wanted to emulate the Photoshop approach, you could: Edit>Copy, then File>New From Clipboard to duplicate the image into a new document. Document>Colour Format>LAB to convert to LAB16. On the Channels panel, ignore the Composite options and find the layer channels below them (usually Background Lightness, Background AOpponent etc). Right click Lightness>Create Greyscale Layer. Select this greyscale layer, Edit>Copy (or CMD+C), then paste it into your original RGB document (Edit>Paste or CMD+V). If you wanted the composite Lightness channel pixels (rather than the isolated greyscale channel), do the same as above, but look at Composite Lightness instead, right click it and choose Load to Pixel Selection. You can then Edit>Copy this and paste it into your original document. Hope that helps!

Power spectral density represents the document view in the frequency domain, so it will give you an idea of the frequencies your image is made up of. It's useful for examining the complexity of your document - more "noise" and scattering on the graph represents more high frequency detail; so sharp pixels, noise, etc. It's also useful for identifying FPN (fixed pattern noise) and periodic noise, which you can remove with the FFT Denoise filter. Outside of some edge cases like astrophotography star stacking, image cleanup, etc it has somewhat limited use, but it's handy for analytical purposes. You could theoretically use it to gauge pre-processing for images to increase compressibility; for example, examining the results of denoising and other convolutions. Hope that helps!

Hi, have you tried checking the Texture Only option on the context toolbar? The patch tool does tonal and textural blending by default, and in this case it's not producing the expected result. Even with tonal matching, the result you're getting looks quite odd - have you got any other work going on in this image/document? What does your layer structure look like? Also, if you try right clicking the layer you're working on (usually named Background) and choosing Rasterise, does this alter the patch tool behaviour at all? Thanks and hope to hear back from you!

Hi, it sounds like you've downloaded the trial of Affinity Designer and are watching Affinity Photo videos (Designer has fewer tools in the main Draw Persona). Both apps have all features available for their trial versions, so you just need to work out which app you're after - Photo for image/photo editing or Designer for art/vector/design work. Hope that helps!

I believe he means was the raw file originally in a proprietary manufacturer format (e.g. ORF or NEF) - and if so, how was it converted to DNG? Seems it was originally a CR2 from a 5D Mark II. The file the author has provided looks like a Linear DNG exported from Lightroom/Photoshop with specific Camera Raw tagging to retain all the non-destructive editing. Photo appears to be ignoring the RAW data and loading the (untagged) embedded preview, so it looks like it could be related to how Linear DNGs are written back out of Camera Raw/Lightroom. There's clearly enough of a structural difference there to cause an issue with Photo's DNG import. Thanks for reporting it, we'll pass it onto the developers.

High pass sharpening isn't covered specifically in any of the official iPad tutorials but I did do a walkthrough of an image edit that uses it as a final step. Check out this video at around 11:50 - It covers adding a live High Pass layer, then setting its blend mode to linear light to achieve the sharpening effect. Hope that helps!

Hi Owen, apologies that your post has gone unanswered - please could I ask for a bit more information from you? Are you able to provide document details such as the colour space you're editing in, and also colour format? (8/16/32-bit) Additionally, have you profiled your monitor or are you using the default iMac calibration profile? The only way I can reproduce what you're experiencing is if I'm working in 32-bit - in this case, the navigator preview will always be managed by the display profile transform, and so accounts for the difference if you're previewing your actual document in linear light or through OpenColorIO. With regards the soft proofing, if you enable gamut check, do you get clear out of gamut warning areas on your document? Look forward to your reply and hope we can solve this - if you're able to provide screenshots that would be a great help too. Thanks!

Hi kazu, You should be able to use ^ as a power operator (e.g. SR^1.2) - is this not working for you? Additionally, you can use other bracketed operators such as sqrt, abs (for rounding), and you can currently use sq and sin as interpolation curves. Hope that helps, let me know if you have any further questions!

Hello, all of the official tutorials typically refer to "iCloud Drive" when accessing files from cloud storage - the ability to add files from other cloud storage services is explicitly covered in the Opening & Saving video here: Photo taps into Apple's general storage support, so all you need to do is have the relevant cloud storage app installed - whether that be Dropbox, Microsoft OneDrive, Google Drive, etc. The above video briefly shows you how to access these at 0:49. You can however always stick with Apple's iCloud Drive, and you can purchase extra space for this by going to your iPad's Settings, then under your account choosing Manage Storage. Although Apple Photos uses iCloud Drive to store your images, Affinity Photo can access the Photos layout separately (via "Import from Photos") as it's more user-friendly. Hope that helps.

... and again to say I've added the latest video, "Portrait Panoramas".

It's also worth pointing out that the help for both apps is available online (currently in beta) in this thread here, with some improvements including page printing and language switching: Alternatively, you can jump straight to them using these link shorteners: affin.co/designerhelp affin.co/photohelp

Heya, just bumping this - added a new set of "Tonal Effects" macros

... and another bump to let you know I've posted a new video on using polarisers!
