  1. Dear John, Thanks again. I did it, thanks to you. Do what you said to get the difference. The common area is black (of course) so it's a trivial flood select then cut. This leaves the bit I want but with the wrong colors. Select that bit, set opacity to zero then merge it with the layer that had the correct colors. Then merge these layers. The selection stays through the merge and, since the selection came from that layer in the first place, it is exactly in the right position. This, of course, merges the colors but, since I set one to be totally transparent, the merged color is exactly what I want. Now I simply cut and paste into a new layer. While, in theory, I could have selected this in the first place, in the situations I have, it is very complex and would have taken forever. So this rouse is a way of selecting the difference between two layers (or many layers) when these differences are rather complax. Couldn't have done it had you not set me off in the right direction. Robin
  2. Thanks John, This is a very interesting suggestion. It almost works. It gets rid, completely, of the common areas and that is great. However, it blends the areas that are different. Instead of a blend in the areas that are different, I want the pixels from the top layer only. This then represents the addition I had made in the collage. Think of a big sheet of blue paper as my start. I photograph that and make it layer 1. Then I scatter some leaves on the blue paper, photograph it and make that layer 2. But I want to create (for future editing purposes) a layer that has only the leaves. (I could do it by selection but this can be tricky in my case.) Your suggestion obliterates the blue background and that it great. However, the bit left is a blend of the leaves and the blue that was behind the leaves. However, it's a great idea and I will think some more along these lines. Thank you.
  3. I want to make a new layer which is the content of one layer minus the shared content of another layer. In other words, I want to isolate the difference between two layers. I have used a stack to remove this difference (as in the tutorial) but I don't want this discarded. I want it as a new layer. The problem comes from a physical collage that is being made in, essentially, four physical layers. I want to have a digital counterpart and I thought about doing it the following way. Make layer 1. Photograph it. Add layer 2, Photograph it. In Affinity Photo have these two photos as layers. Subtract, from image 2, what it shares with image 1 and save as a new layer. Continue in this way till the collage is finished. I now have a photo of the final collage BUT if I do need to edit this, I have isolated the separate entities and that will make the editing so much easier. I could do this by selecting pieces from the final image but this can be very tricky. It would be so much easier if I could do this as the collage is being made. In short, it's like the removal using a stack with the additional capability of "remove to a new layer". I'd be happy to have suggestions.
  4. Hello, Thanks for moving my comment to this forum. Here I will take the opportunity to give a better idea of the user interface I feel would be very helpful. I made a mistake. Since I had not used it for a while I got mixed up with which SyderCHECK I had. I have the 48 patch one. However, I think it would be nice to support both the 24 patch and 48 patch charts. BUt I would like much more flexibility. The ability to work with several common charts (Datacolors 24 and 48 but other too). The ability to select a subset of colors from the chart rather than them all. (I may have an image where certain tones are utterly critical but others are not.) The ability to design and store my own custom chart. That would be fantastic. In the meantime,... Great product.
  5. I have searched but could not find any mention of using color charts for color correction in photos. I apologize if I have, inadvertently, overlooked one. I see that I can use a single white pixel or patch to help correct white balance and, indeed, this is helpful but I am wondering if I can do more. I have the Datacolor SpyderCHECKR 24 color patch and used to make test shots with this in the photo. I know that other software has a very simple way of using the entire chart to optimize white balance correction. Though tedious, I could enter a list of true colors and then select the corresponding pixels in the photo. Does anyone know of an add-on or separate software that would take this information and return the optimized color temperature and tint correction for Affinity Photo. Having such a tool would enable me to get a good starting point for my processing of RAW files. With thanks, Robin
  6. Hello Walt, I feel a bit embarrassed. The problems I had with Canon were very real indeed. It took forever to get them all sorted out but, after that, I have made many profiles, all successfully. So, when the same thing happened with my new Epson printer, I assumed that the problem must have been with the printer. I then went off going through the entire litany of things that had cropped up in the Canon episode. Eventually, after forever with no success, I decided to go through the whole process again. This time - no problem. What was wrong the first time? Ah well, sorry, shame on me, I know I'll be shunned by all on the Forum from now on but, well, I had forgotten to switch off color management in the printer when I was printing the test patches. I've done it correctly so any times, why did I mess up this time and why did I not think about this after spending so much time messing with the printer. I guess my brain had become conditioned after the Canon episode. On a brighter note, I did manage to print out the book, individual signatures, and I got the alignment done perfectly but it was an enormous effort. If I ever again have images that cross the spine, I will restrict them to the center sheet of a signature. So one book is now behind me and I need to find an artist for the next one. Thanks to all, Robin
  7. Hello everyone. I had hoped that such problems were behind me - but no. To begin with, let me say that I had similar problems with my Canon PRO100 but, after months working on them with help from Forum members, several Canon Tech people and Datacolor, I eventually managed to get my printer NOT to do its own color management (Even though color management was set to NONE, it still did it.) I was using Windows 7. Now, on another PC, running Windows 10, I have the same problem with an Epson XP960. The Auto setting does a pretty good job (I am using Epson paper) but I wanted to do better and so created (as I have done many, many times) custom ICC profiles. Soft-proofing on the monitor (a high-quality,14-bit LUT calibrated model) worked just as expected. I then, as the manuals instruct, switched off the color management in the Epson printer dialogs and selected color management by the App in Publisher (and in Photo). I then selected the ICC profile I had just created and printed. The prints were very dark, nothing like what the soft-proofing suggested (and I made sure that I de-selected the soft-proofing before printing). I then tried the additional things that, eventually, got things to work on Windows 7 with my Canon PRO100. (This entailed going into Properties, selecting the device and setting color management to Use My Settings and (manually) adding the new ICC profile to the list. Sadly, and although I have tried all the fixes I had to use to get the Canon PRO100 NOT to do color management (and let the app do it) I simply cannot find a way to STOP my Epson XP960 from doing its own color management. To summarize, if I let the printer do the color management, things work reasonably well. If I try to do better by having the app (either Photo or Publisher) do the color management (selecting the appropriate ICC profile and Rendering Intent) and selecting; More Options -> Color Correction -> Custom -> Advanced -> No Color Adjustment, the prints are much too dark, wildly different from the originals. Does anyone have a suggestion?
  8. Thanks to all for the suggestions. On the border-less printing, I'll try using a margin, registration marks, overlapping prints using the registration marks and then cutting both sheets at the same time just to make sure that the cut lines fit perfectly. On using a print shop, I did find one that was a reasonable price, but they don't use any color management and only use eight inks on their twelve ink Canon printer. I have been encouraging them to try color management (and all twelve inks) and they did say that they would (at least) let me show them how I calibrate my own printer/paper combination. I'll keep working that angle too. As it happens, there is a company in Portland (Oregon) whose business is color management and supplying the commercial printers with ink and inkjet printers (Epson). I chatted with them and was told that MANY of the printers here use no color management. It's a pretty steep learning curve for me and I very much appreciate all the help the Forum has given me. Robin
  9. Thanks Walt. Once again you have helped me out. I was struggling to get control of the places to do the split and did not come across the guide manager. This was a great help. My first attempt looks hopeful though not quite thee. The problem may be in the printer with its border-less printing. I'll work on that. My goal is the following and you may have a better suggestion. I got an artist to do paintings for a short story I wrote and I organized an exhibition of the artist's work. The paintings look great but they (and obviously the exhibition) was in Scotland and I live in Oregon, and the eight paintings were around 4 feet by 5 feet each. They're still there and it will be a pain to bring them back. So now I am investigating getting a digital artist. I have found one in Spain who thinks that he can handle a file size large enough to be printed out around 40 inches by 60 inches at 300 ppi. While this solves one problem, it creates another. How can I print so large an image. I have inquired of local printers and the quotes vary from $350 to $600 per print. I simply can't afford that. My Canon Pro-100 can do 13" x 19" and so I am wondering about splitting the image and printing it out in sections. I would need to get every line of pixels so that I could align them perfectly. Then I could use acid-free archival tape that is used in book repair to join them at the back. Voila! Okay, so I'm a dreamer. I'll work some more on your suggestion. Thanks, Robin
  10. Hello, I want to split a rectangular image into, say, nine equal parts and have each saved as a separate page (or image). (I will then print out all nine and stick them together as a single image of huge size. (My initial image will have a huge number of pixels making sure that each of the final images will have a resolution of at least 300 dpi.)) I have Photo and Publisher. I have looked at the slice tool but don't think it can do what I want. Is there a way to accomplish this in either Photo or Publisher? If not, does anyone know a stand-alone app that can do this? Thanks for any suggestions. Robin
  11. Hello, I found the key in the Affinity Photo folder and all is now well. Robin
  12. Hello All, I too had the situation that it would not accept the product key for Photo. I wondered if this was a result of an upgrade from Windows 7 to Windows 10. I do have Photo on another machine and tried to check that I had the correct key. However, I cannot find where the key is kept. Where can I check the product key on my working copy of Photo? Thanks, Robin
  13. Hello Mike, Thanks for the offer. That is very kind of you. Montax sent me another email today with more details and suggested that I first try it out on the free version. This seems a very reasonable approach to me and I am quite impressed that they have taken so much care in their responses. I think that I should follow their advice and try it myself first. Since both you and Montax think it will work, I need to learn the steps myself - so why not try to learn now. As I am doing this, I have (via my workaround) produced signatures and so have moved on to the printing stage. I have noticed, for a very long time, that the same image will print out differently (same paper, same profile, same intent etc.) depending on which app I am printing from. This issue is my next big hurdle. I will probably end up asking some questions on the Forum but, to be very careful, I am slowly stepping through things using a few test images I downloaded from the web. I'll let you know how my Montax test gets on. Thanks, Robin
  14. Thanks for the suggestions Mike. My document has images that cover the entire spread and so I have to start with spreads and then have them split (automatically) into separate pages. Unfortunately, when Publisher does this they add extra bleed on the inside of the pages; bleed that was not there. If I could have started from pages (rather than spreads) I would have. I inquired of Montax and they told me that, while what I need was, with a big effort, possible in their software, I would have to do the splitting manually! What they said was the best way to accomplish this (surprise, surprise) was to export pages from the publishing software (exactly what I wanted to do but could not because of the bug in Publisher). So, no help from that source. I have discovered a reasonable (not good but "reasonable") workaround. I make the pages larger by the amount of bleed that I need. (Actual bleed set to zero) then I export pages to PDF. Then I split the pdf into separate files, one for each page. Then I take bunches of pages (as pdfs) back into Publisher; the right number for a signature. This gives me a Publisher file for each signature. Then I print each as a booklet. Voila. I then sew these into a text block. This block is a little larger than need. I then trim it to size. If Publisher could split spreads without adding extra bleed, it would be great. If, in addition, you could print a SELECTION of pages as a booklet (not just the entire document) it would be perfect. In the meantime, my workaround is not too onerous (because Publisher DOES split spreads correctly IF you DON'T have bleed) and the pdf splitting of a single file into many files is also automatic (in my PDF editor). So the entire process is not as cumbersome as my explanation of it is! Note: I don't think I would have come up with this workaround without the input of people (like yourself) on the Forum and (in this case) helpful comments from PDFSam (my pdf editor) support. Thanks to all. Robin
  15. Hello MikeW, The trim size will be 8.25" by 9.75". I am using 11" x 17" double-sided, grain short, photo paper for the printing. I will be following up with your other suggestions. I have, already, tried a free imposition app and have also purchased one. They both work fine on pages but neither can split a spread with bleed into two pages (which would then have bleed only on three sides). I have been checking the status of this issue for over two years. Things change quickly. A bug today may very well be fixed in the next release. I consider this a bug in Publisher since if I print a spread and cut it in half, I get two pages with bleed round only three sides. However, if I first split the spread in Publisher and then print it out, I get two pages with bleed round all four sides. Publisher adds bleed where there was none. Had I wanted bleed round all four sides, I would not have set up the document to use facing page spreads. I have had plenty to do over the last two years and so could go on with other things while hoping that either Serif would fix this or some pdf imposition software would add the feature. But, finally, all the other tasks have been done and the ONLY task remaining is to print it out so that I can bind it. So this is why I asked again. I contacted Serif to determine if they have any plans to fix this. They don't. I contacted the makers of my imposition software and they say that they do have plans to have this feature in a later version. Since it is a highly specific feature (for a PDF app) it is not something that is likely to be highlighted on a company's website. This is why I am now writing to companies to ask them specifically about this feature. I'll keep doing this. Since my document is utterly vanilla (facing pages, starting on the right) like all other books (bar some paperbacks) that I have, I wondered if others might have a solution and could tell me precisely which products (and the price) to get. Obviously, professional printing houses have software to do this but the prices are well beyond what I can afford. Until I find software that can do it, I have developed a compromise, not great but workable. Sincerely, Robin
