  1. I keep finding things for you for your camera club: here is a good video on why 32 bit Pro photo is the best..... today.... https://wolfcrow.com/should-you-raise-bit-depth-and-color-space-before-color-grading-part-two-raw-video/
  2. BTW Neutral shooting only affects Jpgs not raw..... I use the jpgs for immediate processing using snapseed but then when I get home I use Affinity Photo. 14 bit raw encoding is what is preferred for raw.;.;; if you want to talk about color then I recommend you look at these web sites . The author is a painter and photographer and he gives a very good overview of color theory. Folks in your camera club might appreciate this.....https://www.youtube.com/user/EverydayHDR/search?query=color+theory be sure you watch both color theory 1 and 2 which are both shown on this page... There are many others on color theory out there but I like this one as Blake is also a painter.....
  3. I have several 6 TB disks a 4 TB and a 3 TB disk... I remember when disk technology for a 8 foot high disk drive was 256 MB..... I also developed computers in the early days and have a number of patents on them ITs come a long way. AS AP works in 32 bit floating point in develop it gives you a good start for any further work you do in the photo or HDR module. I use the HDR module a lot directly from the develop module. You might try working in 32 bit mode in photo as most of the adjustments work in that mode. Many folks think you dont need 32 bit and if your camera only records in 8 bit then that is true but my cameras have a very wide dynamic range with 36 and 45 MPixels as well as recording in 14 bit flash and I can recover a lot .. You really need the dynamic range for that. I have conversed with many photographers on You tube working in Photoshop who insist that 16 bits is enough but watch some of the videos from James Ritson and you will see the benefits of 32 bits. Its not for everyone, most people will be very happy with 16 bit which is what Photo persona works in when you dont select 32 bit mode..... I have to tell you that 32 bit mode is especially useful when doing astrophotography..... I never have to bracket a landscape photo when I work in 32 bit I have always been able to recover the darks when I expose for the lights..... But then I have the right camera for this as well. As far as your comment on the cost of the books. Well, these are textbooks and are expensive...
  4. In affinity photo raw development is done in 32 bit unbounded float in a linear space according to Serif. My camera takes pictures in Adobe 14 bit not 8 bit which is adequate for a raw picture when you record the raw file in camera as NEUTRAL. I find cameras that record RAW in 8 bit less than desirable. But 8 bit makes the file size smaller but you cannot recover out of gamut data easily especially in landscape photography which is what I do. Its when you do manipulations with the camera raw file in either any persona that you need the extra precision. So when you go to the photo persona you could select a 32 bit space with the assistant. Serif went to 32 bit in the develop persona i Believe with version 1.5 as with version 1.4 when you did even tonal adjustments it would blow through the available precision and give very undesirable results. The HDR persona is of course in 32 bit as well and I tend to do a lot of adjustments there. Then you can continue working in 32 bit mode when you go to the photo persona. Of course you have to scale to whatever format when you output the file... There is a video on how to do that scaling as well
  5. FYI I am a former professor of Astrophysics and former director of the Hughes GPS (WAAS) program with a specialty in relativity theory. C* is the chrominance in LAB and is not separable in any RGB color space . I would not convert RGB to LAB you lose something as the RGB color space is smaller than LAB. I always go directly to LAB then only convert to Pro Photo when all the calculations are done. Again there is a loss associated with this but its what you have to do and to print you have to go further to sRGB...... I am still experimenting with going directly to a 32 bit color space and working from there . In the formulas L is the luminosity and one can use a luminosity mask for this; again I refer to Kuyper..
  6. There is no precise way to do saturation masks in any RGB color space because lightness affects saturation and lightness is not directly used in any RGB saturation mask approach I have seen. Using the HSL and HSV adjustments in Affinity is a rather poor choice as this will give significantly different results for brighter and darker images.I do not recommend this approach. It does not take into account lightness. (I am working on a solution in the LAB color space that includes luminosity masks and uses color inversion masks and the difference and or subtract blend modes but I am still working on it.) In LAB luminosity is directly applied and much easier to use the formula there is: which is not recommended as there is no chrominance (C*) relationship to other gamuts from LAB , an approximation to what the eye sees is given by . This is still an approximation the explanation can be found in wikipedia here: https://en.wikipedia.org/wiki/Colorfulness or on any book on Color Theory such as https://www.amazon.com/Color-Vision-Colorimetry-Applications-Monograph/dp/0819483974/ref=sr_1_13?ie=UTF8&qid=1547755006&sr=8-13&keywords=The+physics+of+color+theory Tony Kuyper who is cited in the dialogue above has done an excellent job of getting to the best practical solution for saturation masks and I have been using his approach up to now. He has also done a superb job on luminosity masks
  7. I agree, it really hampers me especially when i try to use the color burn/color dodge blend modes...
  8. A number of times I found that I could not record macros when certain steps where required. I would like to see the macro capability improved. For instance, the unfortunate thing is I have not been able to create a macro for saturation masks.. It appears that affinity photo macro capability does not allow you to reorder or nest layers within the macro. Can that be allowed in the next version 1.7?

  10. I still use lightroom for cataloguing my pictures. 1. Will Affinity photo have a cataloguing capability in the near future? 2. Lightroom does not recognise the extension afphoto, so I cannot save Affinity worked photos, I have to export them This presents another problem. LIghroom recognises the extension TIF but Affinity saves as TIFF, I cannot save in place. I have to export then import every photo into Lightroom. This takes considerable time. Is there a way to make Affinity photos recognisable in Lighroom?
  11. Thank you First Defence for your response. Affinity Photo will not allow you to save a document as TIF it requires TIFF and it sends an error message to that effect. , I had tried this already along with a number of other ideas. Lightroom catalog recognises both TIF and TIFF.It would be great if Affinityphoto would do the same. Thanks..
  12. the flood select tool when applied as new or add only changes the tolerance when you drag it over the area you wish to select. Nothing else happens. The tolerance goes to 100%. I dont believe this should happen. . While it erroneously increases the tolerance it does Not actually select anything... Also when you uncheck contiguous it still does not select the noncontiguous areas. Please repair. The selection brush tool also does not seem to select anything anymore much of the time and when it does only where the brush actually passed over
  13. thanks but none of those corrections provide for projection (perspective) cropping of part of an image and extending the perspective to larger segments of the image while maintaining the selected perspective then cropping to the selection. This is very useful to get architectural images perspective the way a user needs it to be for architectural photos. Please look at the perspective crop tool in photoshop. That is what I would like to see. Maybe someone has figured out a way to do this with macros? thank you
  14. Maybe I am missing something but I would like to see a projection crop tool as it is in photoshop. This would help greatly for architectural work. This would work great when shooting with a wide angle lens. Maybe I am missing something but I dont think it is there now. Thanks
  15. great writeup and tutorial. you might mention though that you can do color grading with the exclusion and difference blend modes. IF you add say a blue fill layer and set the blend mode to exclusion, then because of how the math works, you will get blue in the shadows and yellow in the highlights. Color grading results when you reduce the opacity of the color fill layer.. to your desired layer.. Difference works similarly
  16. I cannot seem to increase the font size in the macro library it is much too small for me to see. Do you have any suggestions> Also in the preferences, you can select font size as default or large but large is not very large and is still hard to see. Thank you
  17. Let me respond to your points RCR I do appreciate your comment. 1. irrelevant, you could always increase the field size. IF the font is too small and unreadable then it does not matter how much of unreadable text you can display 2.Similarly irrelevant, if I cannot display as much text again i can increase the field size. IF I can't read the font it is irrelevant how much unreadable text i can display 3. I do not have this problem with other software such as lightroom and photoshop . the font there is a little bit bigger, big enough to read...
  18. I can do it this way but it changes the resolution of my monitor. There needs to be a way in affinity photo to make fonts large enough so that they can be read. Right now this is not the case. even in preferences you can only change from default to large font size but the large font size is not large at all. In the macro library when you open a macro the print is so small that it is unreadable. This makes the macro feature basically unusable the macro library font size is also not controlled by the selection in preferences. It is very very small. Please provide a way to enlarge fonts everywhere within affinity photo
  19. the cursor in affinity photo is often very dark, in fact I have trouble seeing it. This happens when a variety of tools such as flood select etc are selected. Is there a way to make the cursor more visible?

    flood select tool not working in APhoto 1.6

    thanks for the input. No I have the tool set to add, I make sure of that
  21. When I export a document, the dialogue only lets me choose from a very limited number of locations ( the recent ones) it does not let me choose a general location. I have to save the file to one of the highlighted locations and later move it to the desired location. This is an extra step that should not be required. Please allow export to ANY location on the computer that the user wishes.
