  1. Hi everyone, I put up a blog post about using blend ranges in the way people often use luminosity masks. You can check it out here: http://theeagerlearner.com/blog/ Hope it's of some use to you & cheers, Simon
  2. Here's a tweak I've just been playing with for working with adjustments. The general problem is that when you are applying an adjustment, you often don't want it to be applied as much in the darks and lights. For example here's a picture of my wife making coffee: Now if I add an HSL adjustment layer (Layer/New Adjustment Layer/HSL Adjustment) and slide up the Luminosity to make the picture lighter, it kind of goes hazy: A trick here is to use Blend Ranges. Click on the cogwheel in the bottom right corner of the HSL panel. Then drag both ends of the right-hand graph to the bottom. Uncheck the 'Linear' checkbox. Now grab the middle of the graph line and drag it up. This applies the adjustment more to the mid-tones and lets it drop off towards darks and lights. The result is much more pleasing. You can play with the shape of the curve (click and drag to add more points) as well as the adjustment. For example in the HSL panel you can drag up the Saturation to strengthen the colour. The same principle can be applied to any of the non-destructive adjustments. Isn't Affinity wonderful?
  3. Affinity Photo includes an awesome "Blend Ranges" feature that I use to accomplish exposure blending with my photographs. It takes a little practice, but this tool is more flexible than Photoshop's "Blend If" sliders (because it supports customizable and non-linear luminosity feathering), and more efficient than Luminosity masks (smaller file size). I would love to see the efficiency of this feature further improved by the addition of presets within the blend ranges panel to create common blending curves, which would save me the trouble of frequently recreating similar curves over and over again. Presets such as "highlights only", "midtones only", "shadows only" or combinations of these would be a real time saver. It would also be great to see the histograms of the current layer, and composite histogram of the layers below, drawn behind the respective curve graphs in this panel. Without histograms it's hard to visualize how the luminosity information is distributed across the current layer and the layers below, and creating the blend curves becomes a bit more of a trial-and-error process to find the right spots in the X-axis to start or end your curve. Photoshop users have plugins like Raya Pro and Lumenzia that make exposure blending easier, although they suffer from poor UI and other issues. It would be great if Affinity Photo put some more effort into fleshing out the Blend Ranges feature for photographers who want to do manual exposure blending.
  4. Start with an image in RGB colour format. Blend Ranges. Red. Change Source Layer Ranges graph. Switch to LAB with Document/Colour Format/Lab. Blend Ranges dialog is still showing Red. Hmm. Turn off dialog. Open it back up again. Now it allows for LAB changes. Click on Master dropdown. Go to Lightness. Oh look! The adjustment for RGB Red now seems to be applied to Lightness. (Hmm - what about CMYK, which is a four-item list? Changing Black then switching to RGB seems to do no harm though the blend ranges effect is lost. Switching back to CMYK restores it.) Presumably, the Blend Ranges records the channel used as a position in the drop-down list and doesn't notice a change in colour format.

    'Luminosity mask' selection macros

    Following on from a previous post, I've created three sets of macros for selecting a part of an image based on five Blend Ranges 'luminosity' curves (nominally called Blacks, Shadows, Mid-tones, Highlights and Whites). You can download the zip file here (the forum doesn't seem to like zip files, so I put it on my website). A few points of note (more in the included .pdf file): The 'Preview' set just cuts out the selection so you can see exactly what is being selected. It also lets you inspect the Blend Ranges curves. The 'Select' set turns this into a selection in the image. The 'Blend' set does the same for adjustments and filters. Curve overlaps are deliberately symmetrical so together they should sum to 100%. All sets include all contiguous combinations, such as 'Blacks+Shadows'.

    Blend Ranges naming

    Just a tiddler, this one. Hover over the cogwheel and it says 'Blend Ranges'. Click on it and the window title is 'Blend Options'.
  7. When you´re working frecuently with the blend ranges, it´s a little annoying that the window open always in the center of the image, you have to move it every time in order to fully aprecciate the effect of the changes you make.
  8. Hi there. I'm trying to find a workflow for combining several (5-7) bracketed images with brightness masks in landscape photography. Something similar to the Tony Kuyper panel in PS. The hdr module, for the moment, does not provide acceptable quality results. I've sailed through the meager material about using Blend Ranges to replace brightness masks. Lots of potential, and plenty of empty space yet. I would appreciate sharing your experience, your workflow, or some useful tutorial video on this topic. Many thanks in advance.
  9. Do the devs know the equivalent formula of AD/AP blend options versus PS Blend options with their sliders? I want to believe there is an equivalent solution to make them match just not sure how to do it YET.
