  1. In photoshop when applying a curves layer there is a hand tool that allows the user to select a point in the image and that point will be represented on the curve so you can adjust based on a particular area of the photo. Does this function exist in Affinity for iPad? I searched and don’t see in the app that I do anything other then creating points on the curve and adjusting.
  2. Hi, I have a curves layer, I click the select button and my layer disappears? What am I doing wrong?
  3. Hi there I want to match the color of a subjet to background using curves adjustment layer. I wanna know if it is possible to sample three pixels (darkness pixel, midd tone pixel and lightess pixel) and apply those exactly values to subject layer so I can fix the colors, but using curves adjustment layer
  4. I know I've suggested a similar feature, but all this talk of smoothing curves brought this up in my mind; in addition to a tool to smooth a curve, Affinity Designer should also have the opposite. I am of course referring to Midpoint Displacement, which would allow illustrators to make non-uniform curves more easily than having to draw each node individually. Being able to smooth curves is indeed important, but as it is, it's really hard to produce a line that doesn't look uniform, and a roughening tool to add pseudorandom midpoint displacement would make illustrating much less time-consuming.
  5. My dad just downloaded the newest version of Photo for Windows. When he tries to add a curves adjustment, the histogram is greyed out and doesn't match the curves in the main histogram panel. Individual color channels show the correct graph (albeit greyed out), but when he chooses the master channel, the graph is wrong. This happens on all new documents. I've attached a screenshot of the curves adjustment panel next to the histogram panel to show the difference.
  6. hello designers , anyone knows how to curve angle (from inside ) like the picture ? thanks
  7. It was brought up in this topic: https://forum.affinity.serif.com/index.php?/topic/16297-any-way-to-force-everything-to-paths-when-exporting-to-svg/ Essentially, when I export to svg I want everything exported as <path>'s but I get some <rect>'s even though they are displayed as (Curve)'s. Is there a solution for this?
  8. Here's another thing that's keeping me stuck using PS for the near future, as I haven't found a suitable replacement in another application... I require precise adjustments of curves for when I create calibrated contrast correction for alt process photo printing. I regularly print using gum pigment (aka, gum bichromate), kallitype, gumoil and cyanotype techniques. The overwhelming majority of my fine art prints are done this way. To get the best results, it is necessary create compensation curves to correct for the deficiencies of the print process. They are all different, and ideally one would create individual curves for each kind of paper used, as well as for the different processes. I feel confident saying this is the common practice amongst alt process photo printers these days, so I'm certainly not the only one who would benefit. A full description of the process I use can be found here: https://www.freestylephoto.biz/alternative-process/making-digital-negatives Please take special note of Figures H and I in the article because these illustrate exactly what I'm needing to do with curves. What I need is the ability to precisely input the required I/O numbers into the curves dialog. Not only do I not see any way to do this in AP's curves, I don't even see any sort of scale that would clue me in to where I am on the curve. I am able to read gray values the way I need with the eyedropper, but without being able accurately translate those numbers to a curve, I'm stuck with only half the tools I need to do this.
  9. Ok, I get it, each line or curve drawn gets it's own layer. Sometimes this is more of a pain when I am trying to edit. I know you can group the layers, however it still isn't convenient when going from one curve to another. Is there any way at all to put these lines or curves on one layer to make it easier to edit them, like other apps do? I am working in vector here.Forgive me if this question is in FAQs, but I do not have time to go through them all.
  10. I posted the following thread 3 years ago but not a single person until today advised me to post that topic in this thread, claiming that no one from Serif diligently reads this forum such that my post was sure to have been overlooked these 3 years. Seems odd to me, but fine. Here it is: I would advise Serif to just move that thread into this thread. I would prefer that since I don't want to lose all the supportive posts in that thread. For truly, it is more than just me who wants that dropper tool added to Affinity Photo. Thanks.
  11. Greetings, I have been using Affinity for quite some time now and have never had an issue with this before - it suddenly showed up with the most recent update and persists in all affinity programs - photo, designer and publisher. The issue is that when I export text as curves into PDF, letters like "I" and "l" (L) become thicker than they should be. As far as I know this doesn't mean that it'll be like that when printed, it is simply shown like this in the PDF. Some suggest to disable certain options within their PDF viewers, but this isn't a real solution as certain PDF's are shared among clients and various other people and having to let them know every time "hey, you should disable/enable option X" isn't efficient. The solution to this issue was finally presented in this very old article : https://www.underconsideration.com/speakup/archives/004301.html Adding additional anchor points made everything work and show correctly. I have been using the same method all the time within Affinity software as well and it worked perfectly - since the last patch that is. Now, I always get thick lines no matter how many anchor points I add and now matter what option I enable or disable in my viewer. I have even tried adding a very small rounded stroke around the letter i (I) and L (l) to avoid this idea of it being a simply thin rectangle with only 4 anchor points : But it didn't help. Even worse, the letter was even more thick than before! 😱 Since this issue didn't exist prior to the latest patch and it suddenly appeared, I posted it here on the forum in hopes that someone might know what option perhaps needs to be enabled in the new version, or if it actually truly is a bug. I repeat, this isn't just a PDF viewer issue anymore, adding anchor points is completely ignored during export and the resulted exported PDF even loses all added anchor points, which means the following is happening now : You can open a brand new document in designer Type anything consisting of letters I, for example "I need this to work" Convert the text to curves Add additional anchor points to "I" Export for print PDF with no rasterization of any type. Check up, just in case, convert text to curves Open exported PDF in designer again The letter "I" is not a curve anymore, while everything else is This could potentially cause problems with printers who deliberately ask for text in curves This should mean that there seems to exist a new bug during export to PDF. 😭
  12. Windows 10, Affinity Designer 1.8.0.585 I tried editing the nodes of a curve that I had previously scaled to 0 on the y-axis using the move tool. instead of smoothly following the bezier curve, the stroke jumped between seemingly random points on it instead and the pointer position for editing was only evaluated on the y-axis. Steps to reproduce: Draw a curve Use the Move Tool to scale it to 0 height Pull one of the nodes back into two dimensions using the Pen Tool. The stroke doesn't follow the curve and the cursor is being projected along the x-axis (holding Ctrl in the second screenshot). Edit the curve further. Multiple points may actually match the curve. The same thing happens when scaling to 0 width; the cursor position is then projected along the y-axis.
  13. Hey folks! Here's the case: I am currently working on a logo in Affinity Designer. It is the second iteration and I would like to present him the first vectorized draft of the logo in an appealing layout and with written documentation. I have created the layout in Affinity Publisher and linked the Affinity Designer file in it, so that any changes to the logo are directly reflected in the Publisher document. Thereby I encounter the following problem/s: The Designer file contains text that uses a licensed font that should remain editable until the final version of the logo – but in the Designer file ONLY. If I now export the Publisher document as a PDF for web to keep hyperlinks to references and good readability for example, the text of the linked logo gets exported editable/selectable via Adobe Acrobat – which I don't want at all! If I export the document as flattened and all elements are rasterized, it becomes (even if only slightly) blurred and consequently pixelated – which I don't want either. A possible solution for a feature could be the option to convert any text ONLY in linked/embedded files instead of converting all text to curves during export. I'd be happy to learn if there's another, more convenient way to do this, since it's a bite impractical while the logo's not final. 😀 However, I' m not quite sure if I described the problem in an easy to understand way. 😅 Greetings MrDoodlezz
  14. would it be possible to allow a smaller grid on curves? I am creating new curves for Cyanotypes, Van Dykes, and Platinum prints and need a more concise points on the curve. also the ability to import existing curves would be very helpful.
  15. edited - I'm using ver. 1.7.3.481 -open image (tried 4 or 5 different images), or create new document (created a blank document then paint bucket fill) -add curves adjustment - crash, every time, tried many (10+) times I opened an image and added a curves adjustment and it crashed. It looks like I can't make a curves adjustment layer at all without crashing Photo. Created a blank image and got the same result. I tried every type of adjustment layer and only the curves adj. failed. specs Win 7 Home Premium x64 MSI B540 Tomahawk Ryzen 7 2700x Radeon RX 590 (software version 19.8.2)
  16. Affinity Photo. Windows 10 - 64 bit I have to draw many lines to make a drawing. I selected the "pen" tool with the "lines" modality and the "Add new curve to the selected object" option, which should cause all curves drawn after to end on one level. Does not work. Each curve I draw creates a new level, and I find myself having to manually "compact" all the layers one by one. Any suggestions? Thanks! I enclose an example screen.
  17. Try the attached. On the face of it, it looks like a simple image with Curves adjustment. But when you play with the Curves it doesn't behave as it should (I've tried it with beta and 1.7 release). For example pulling Curves up to the top left does not result in a whiteout (as happens when the original jpg is used). History: I'd just been playing with masks via the spare channel. Duplicate, Threshold to create b/w. In Channels, right-click and create spare channel. Then load to curves. Then load from blank channel to remove mask. I've tried repeating this to no avail. The bug however seems captured in the .afphoto. Maybe you can figure it... before.afphoto
  18. Hello, can someone take a look at these files and let me know what would be the best way to export the file. The exported image detail is not as crisp when exporting and I'm not sure if there are any other settings that I can use to export. When viewing through Affinity Designer, it is showing the detail without any issues (see the bow in the .jpg file and compare to the screenshot directly from my screen). The curves are not showing crisp lines and blow out when exporting. Any ideas? Symphony_Campaign4b.afdesign
  19. I'm requesting that the histogram is part of the curves adjustment display in the Develop persona, as it is in the Photo persona. I've started shooting film for fun and will "scan" the negatives with my digital camera. I'd like to do the scan in RAW even though I suppose it probably isn't necessary. Negative Lab Pro is apparently the best way to invert the negatives but apparently it only works with Lightroom. The other way, after a white balance, is to invert each colour separately with the curves adjustment and move the limit sliders to match the beginning and end of the histogram for each colour. In order to do this properly, the histogram has to be part of the curves display. I apologize if there is some obvious reason why the Photo persona works this way but Develop doesn't.
  20. Where is the Set White Point in Affinity Photo (AP)? Please note that I've been using the AP beta and recently I purchased the app via MAS. I am trying to transition from Photoshop but I am faced with a learning curve. In Photoshop, I hit CMD-M to bring up the Curves dialog and then click the rightmost dropper icon ("Sample in image to set white point") and click on the light parts of my image. That adjusts the white balance and the white point beautifully. I use this all the time on the white parts of scanned images to make sure white is 100% white. I want to do the same thing in AP, but no such feature exists in the AP Curves dialog that I can see. And when I type "Set White Point" or even "white point" in the Help menu Search field, nothing relevant appears. How do I accomplish this in AP? Again, I want a drop tool (or similar) that allows me to click on light areas of the image and set those parts to pure white. If there is such a feature in AP, please note that Photoshop allows me to press the Option key after I click the White Point dropper to see areas that are still dark. That is very convenient to allow me to see where else I should click the dropper to make sure all the white areas are pure white, not leaving any light gray patches anywhere. Does AP have this? Thanks.
  21. I've been playing around with affinity designer and I was trying to make some font corrections when I spotted this problem; I found no way to convert layer effects to vectors, more specifically, the layer's stroke. Is there a way to do this? To expand curves to layer effects and include them in so that they are regarded when I i.e. use geometry functions using them?
  22. I am a beginner in LAB attempting to apply the writings of Dan Margulis, who uses only Photoshop, to Affinity Photo. The LAB underlying functionality is mostly OK, but I have found that the AP user interface could be improved in several places. More experienced users, please comment. 1) In the Curves adjustment layer with LAB selected, the A channel curve is colored green and the B curve magenta. The appropriate colors are green left and magenta right for A; blue left and yellow right for B (with light or high luminosity on the right). 2) Creating a check box on the A and B curve windows for Intersect Midpoint would make it easier to construct color-intensifying curves. This is probably the most important basic move in LAB, and even Photoshop does not have this feature. 3) The Input Minimum and Maximum default to 0 and 1. Though I have not found a use for these, shouldn’t they be -1 to 1 or -100 to 100 or -127 to 127? 4) The Curves/LAB window’s second drop-down menu offers Master, L, A, B, and alpha. Is there a known use for ‘Master’ as in RGB? Nothing I have read about LAB indicates that there is. For that matter, is there any use for Master in CMYK? And how about ‘All’ as an alternative to Master in RGB? Furthermore, the histogram curves displayed for the LAB components here are not positioned the same as when one transforms the document to LAB and displays its histograms. May relate to previous point (3). 5) Photoshop can display the graphs of the various color space curves with the light (high-luminosity) side on the right or left (one-click toggle). This option would be useful to people learning from Margulis’s books, which show dark on the right. 6) Other Affinity users have called for improvements in the Curves window in general, not just for LAB: more precision and ways of placing nodes, a larger or scalable window, saving curves. Because of the sensitivity of the A and B curves to small movements, a fine control on node dragging would be handy, e.g., option-drag would reduce the motion by 1/5 or 1/10. Perhaps it already exists. 7) A LAB curves user on this forum called for a keyboard shortcut to move among the channels. Why not? He needs efficiency in a much-used workflow application. In the same vein, having selected the color space, instead of a second drop-down, radio buttons for the three or four channels would slightly simplify choosing one. 8) In the Channel Mixer adjustment layer, the LAB window A and B sliders need appropriate coloring like the RGB and CMYK. Just for consistency. 9) The Levels adjustment layer makes sense in RGB, but I am not so sure about LAB and CMYK. Does this lead to a useful correction? (Please help me, advanced users.) If you push the existing RGB colors to the AB limits of +/-127 won’t you just create out-of-gamut colors that will have to be distorted back in RGB space? And is gamma defined for this color space? Also, in the LAB window, shouldn’t the correct labels for the sliders be, for the A channel, green and magenta, and for the B, blue and yellow. Similar questions for CMYK. 10) The Apply Image filter and Channel Mixer adjustment layer seem as if they should have similar functionality, but their capabilities and interfaces are rather different. My understanding of Apply Image in Photoshop from Margulis is to blend or replace channels one at a time, sometimes across color spaces, but to do that in AP one has to create a gray scale image of a channel in a layer and make that the source. The destination seems to be all channels of a selected layer, or does one have to separate out those channels as well? The Channel Mixer is designed to specify a single channel as destination, but it appears the source must be in the same color space. Shouldn’t these two processes allow individual choice of source and destination channels in all color spaces? Are equations (Apply Image) and sliders (Channel Mixer) of equal value in practical applications? I don’t think this exhausts these issues, but this post has already exhausted me. My compliments if you have read this far. If you want to know more about Margulis, use a search engine or post here and I will try to summarize what I have earned from a large corpus of writing.
  23. Hi, I'm trying to fill a capital 'O' without filling in the middle of it. As seen in the attached screenshots. I found a post with the same issue, there they were told to select the individual curve layers rather than the group, and then change the fill mode in the layers menu to "Alternative (Even-Odd)". However, I tried this and it didn't seem to work. Is there something I'm doing wrong or something else that might work? Cheers
  24. In the attached image, the top 'example' word is Artistic Text. the bottom 'example' word is text that has been converted to curves and then had the strokes expanded with the menu item under 'Layer.' The L is very off, but other letters are also visibly (although slightly) distorted as well. If there is a setting that bumps up the accuracy of this, then please let me know. Otherwise, the one trick I know to reduce this is to expand the stroke when the shape/text is really, really big (multiply the size by a huge factor) and then size it back down by the same factor afterwards. I do not remember this happening back when I was using Illustrator. Note: This is as of v. 1.7.1 and haven't tried this in 1.7.2 yet. If this has been fixed in 1.7.2, then great.
  25. Don’t know if it’s just me, or if it’s just this file, or if I’ve had the app open too long, or what. All I know is that whenever I try to select the “Curves” adjustment on its own in the Adjustments studio, I get nothing. The only way I actually get the option to adjust anything is by swimming through the long version of the menu. Take a look... F03DE051-AAFC-44D4-8807-021EFC2BF928.MOV
