Enhanced posterise function?
Subclavius replied to Subclavius's topic in Feedback for Affinity Photo V1 on Desktop
Hello Fixx, Thank you. For me, it was slightly easier in that I am working with b+w, so only 1 channel. I had already applied curve and levels adjustments underneath the posterise layer but I found it didn't really achieve the level of control I was after. In the end I found a way to achieve what I was after, ultimately using blend modes in groups (one for each level of posterisation). This is accurate but very 'clunky' and laborious to change and I would still like to see a much greater level of control. It would certainly be interesting to see how posterise worked against a colour LUT in indexed colour mode to produce a probably more predictable or coherent result. -
I'm interested in editing black and white images in particular with the posterise adjustment layer with low levels of posterisation (3-8 levels or thereabouts). The posterise produces the requisite number of evenly spaced levels e.g. 3 levels gives black/mid-grey/white and 5 levels gives black/25%/50%/75% and white, all as expected. When working at these lower numbers of levels I find it would be very helpful to be able to vary the banding/grouping that the posterise function uses to be user-selectable/non-linear. Whilst some of this effect can be compensated with careful use of curves, it would be a whole lot simpler if the boundaries betwen levels were accessible and hence this request for enhancement. It's possible that there's a workaround using multiple groups with levels/curves adjustments combined with blend modes but I haven't found it yet. Any comments would be much appreciated.

I vote in favour of having a separate DAM application. I would prefer something simple which contains no 'processing' functionality (these are already contained in the apps) but is very much superior to a 'file manager'. I find the trouble with Lightroom is that its functional scope isn't well defined and it blurs the boundary too much between processing/editing and file management. In my view it does too much editing and not enough file management. Other applications e.g. Capture One are superior in this respect.

Keyboard shortcut not "visible" ?
Subclavius replied to Subclavius's topic in V1 Bugs found on Windows
Thank you. I can confirm that the latest beta build (1.8.1.611) corrects the problem. -
Keyboard shortcut not "visible" ?
Subclavius replied to Subclavius's topic in V1 Bugs found on Windows
Hello PaulEC, Thank you, that explains why I can't find it on the menu. The shortcut ought still, in my view, to be visible on the User>Preferences>Keyboard Shortcuts so it can be changed. -
Keyboard shortcut not "visible" ?
Subclavius replied to Subclavius's topic in V1 Bugs found on Windows
Digging a little further I found the following topic: https://forum.affinity.serif.com/index.php?/topic/60033-re-apply-a-filter/ from June 2018 which shows a picture of the Repeat last filter option. This appears to have been removed or left out of later versions -
Affinity Photo 1.7.3.481/Windows 10 I was assigning the keyboard shortcut <ctrl>+<alt>+<f> (to New fill Layer) only to discover that it is duplicated. It apparently clashes with <Repeat Last Filter> but I cannot find that command in the User>Preferences>Keyboard Shortcuts menu to remove. The newly assinged shortcut works successfully as it overrides the <Repeat Last Filter> but it would be nice to be able to remove the pre-defined assingment (or assign that to another key combination).

(1) the combination Ctrl+Shift+] and Ctrl+Shift+[ is assigned by default to Arrange>Move to Front/Back. I was unaware of this and assigned the combination to Document>Rotate 90 Clockwise/Anticlockwise. I have been using the combination quite happily until I discovered the the clash. The issue is that AP does not warn that this is a duplicate combination (2) I have been unable to assign any keyboard shortcuts using the arrow keys (up/down/left/right). The default keyboard shortcuts such as Ctrl+Alt+Shift+Left (Flip Horizontal) work ok in practice Any comments anyone?

Can't load LUTs I created in AP itself

You're welcome -
Can't load LUTs I created in AP itself
Subclavius replied to mircokopf's topic in V1 Bugs found on Windows
I always run AP full screen so can't really answer your question but I would suspect that there's not much in it. However, I have noticed that the first time that AP loads a LUT it takes significantly longer than subsequent times. I guess that AP has to load up additional libraries from disk into memory -
Can't load LUTs I created in AP itself
Subclavius replied to mircokopf's topic in V1 Bugs found on Windows
It does work though, albeit slowly! I imagine that the processing time is heavily dependent on the computing power available to you. Here are the statistics from my machine (windows 10 64 bit, AMD FX6350 (6 core), 16 GB RAM and AMD Radeon R7 200 series graphics card). I created a LUT from AP at maximum export detail level of 126x126x126 which gives a file of 51.5MB. It takes 12 seconds to load and process the file. AP will also use the graphics processor and any (and sometimes all!) available memory. If your machine is taking minutes to load it, then probably you're running into memory/processor (or just possibly graphics processor) limits. If your machine is 32 bits then you should consider upgrading. Good luck! -
Can't load LUTs I created in AP itself
Subclavius replied to mircokopf's topic in V1 Bugs found on Windows
Hello mircokopf, I've tested LUTs both created within APhoto and externally, including one I created from scratch. As far as I can tell they work just fine and the filename doesn't seem to matter. You say that no files are showing up in the file explorer dialogue. What file extension are you using? According to the help, the following file types are allowed: I always use .cube. Can you provide any more details? -
Affinity Photo for Windows - 1.7.3
Subclavius replied to Patrick Connor's topic in News and Information
Dear Affinity Team, Thank you for the latest update, particularly the bug fix with masks in groups. Had previously to revert to 1.7.1 to continue. I agree with mapline in that all fixes, major or minor, are appreciated, please keep them coming! Nigel -
Hello carl123, Thank you. That has fixed the problem. I'm glad someone understands this stuff! I'd like to leave this post open for the moment: perhaps a knowledgeable person from Serif would like to comment, on whether this is likely to be addressed or added to the stack of feature requests, or simply closed.

I want a macro to add 2 pixel layers at the top of a AF layer stack, fiddle with them and then group them together. When attempting to record the macro I can get everything done except that last bit (grouping) because APhoto does not permit selection of more than one layer at a time when recording a macro. I have seen work around methods but they don't work for me because the layer stack contains an arbitrary number of layers and I only want to group the top 2. Am raising this as a bug rather than a feature request as I find it annoying. At the moment I have to use the work around of an almost complete macro and do the grouping (and naming) by hand. Any help would be welcome. Nigel

Need Precision Curves Adjustment
Subclavius replied to martinch's topic in Feedback for Affinity Photo V1 on Desktop
Hello martinch and Old Bruce, If it's of interest, I posted this method in the tutorials section of the forum: It was tested on a 1.7.0 beta but it appears to work in current production 1.7.2. Any comments would be appreciated. Nigel- 7 replies

Suggested Additions for Publisher
Subclavius replied to Archangel's topic in Feedback for Affinity Publisher V1 on Desktop
I very much second the idea of an import facility for legacy PagePlus files. I can understand the pressure to get AP out there but I can't help feeling that Serif has let down its legacy users of PagePlus here in not supplying it. I have seen it suggested that export -> import can be achieved by means of a pdf but I find that wholly inadequate. The elements of the page (e.g. a table) are lost as functional elements and only the 'picture' content appears. Short of a turnaround from Serif it means starting again from scratch. Nigel -
I have posted an article on how to set up curves manually in the Tutorials forum: It uses a LUT and requires some manual editing to set up but it isn't rocket science. Nigel

Hello All, I'm posting this in response to the following thread: I was also searching for a method of inputting (x,y) number pairs into Affinity Photo to make a compensating curve for digitial negatives for alternative processes. It looks to be possible by using a 1D LUT (Look Up Table). The enormous advantage of a LUT is that the file (typically with .cube extension) is manually readable and editable. I've put some details and screenshots below as 'proof of concept' (it means I haven't tested it in practice!). Pic 1 shows the original image (test 2 bw [original]) - it is a greyscale image Pic 2 shows a typical alternative process curve made up with a curves adjustment but not yet applied (test 2 bw [typical alt process curve]) Pic 3 shows the above curve applied to the image (test 2 bw [alt process curve applied]) Pic 4 shows a 1D LUT created from the curve in pic 2 applied to the image (test 2 bw [alt process curve via LUT]). To generate the LUT data I printed the adjustment curve on paper and measured it! Notes on method: Note that this method ONLY works with the current beta version (1.7.0.293). I have tried it in the current production version but the LUT implementation is flawed and it does not work! There are minor differences in the histogram between pics 3 and 4, probably due to the sampled nature of the LUT with its linear segments (and also measurement accuracy!). The method utilises a 1D LUT - pretty much what they were designed for (although the idea was for video implementation). However 3D LUTs also exist and if you export an LUT from AP then it will generate one of these. Notes on LUTs: An LUT relies on having equally spaced points along the x-axis. This is a MUST. If you have made non-equally spaced density samples, it will not work or you will have to interpolate. An LUT can have arbitrarily many data points. In this example there are 78 so that the important information in the rapidly changing areas of the curve is captured although it means that the curve is over-specified in the linear segment. The format is self explanatory (see example). Comment lines begin with a # character. Here is the link to the Adobe LUT specification for those who want to delve further. There is no specification for the x-axis data points. They are assumed to be equally spaced. The numbers supplied are for the y-axis data points and there are 3 of them (in the given range 0.0 to 1.0) one each for RGB. It is important that the RGB numbers are identical otherwise you will get a coloured output. I have used 5 decimal places here but it's arbitrary. I've attached below the sample LUT that I made up - the numbers were created in an Excel spreadsheet. Feel free to adapt it. I would be interested in any comments. Nigel LUT test 2 bw.cube

AP Closes randomly
Subclavius replied to TEcHNOpls's topic in [ARCHIVE] Photo beta on Windows threads
I get this behaviour too. It happens having edited a picture when I click the top right 'x' to close. AP asks to save to when I click 'yes' and then AP itself closes. If I save the edit first (File>Save) and then close the picture by clicking 'x' it does not happen. It's very annoying as I constantly need to reopen AP. Nigel -
Hi Chris B Thanks for the update. I shall bear it mind when editing. Nigel

Affinity Photo 1.7.0.284/Windows 10 64 bit Am having problems with AF redraw after simple changes e.g. adjusting a curve (consistent with certain files) or making a layer invisible and then visible (intermittent, again only with certain files). I have attached 2 pics - the first shows the setup before and the second shows what happens when the curve in question is adjusted. The only (simple) way to get back to a picture again is to click on the visibility icon of the composite channel to force a redraw. With the selected file (and another that I have) the fault is reproducible but it doesn't occur for all files. The only consistency I can find with files that cause the fault is that they are large 16bit greyscale file with 2 groups. I haven't got this to happen - so far - with only 1 group. I don't know if this is the same fault as thread 78221 (strange redraw issues). Any help would be appreciated. I can upload the file if required. Nigel [Edited to correct title]

Hello Gabe, Thank you for the reply. I had already looked at the video tutorial but didn't find it really helpful in the context of this query. Your reply did however enable me to work out how to get a black and white image though. It seems that the 'meaning' of the axes changes from RGB to LAB. In RGB mode the vertical axis is dark to light whereas in LAB mode the vertical axis is blue to yellow or green to magenta. Thus in LAB mode the neutral point of the axis is not at the bottom (as in RGB mode) but half way up. If both the AOpponent and BOpponent curves are set to horizontal lines half way up (removing all colour information) the result is indeed a black and white image representing only Luminance. Clearly when both curves are set to horizontal lines at the bottom of the graph the resultant colour is thus blue+green -> cyan I would find it very helpful if the vertical axis could be coloured with a graded line from blue to yellow or green to magenta. Similarly on the RGB a graded line from dark to light would help. It's only a small wish in a great sea though! Thank you, Nigel
