  1. Hi, I have been restoring some old black and white photographs (really old). I typically choose first the Black and White adjustment first so that I can play with the color sliders. What I noticed is that sometimes nothing at all happens to the image when I move the sliders and sometimes something does change. My question is: If you are working on an original B&W image why do the color sliders respond sometimes and sometimes not, since there is no color information? And if they respond, based on what do they respond (again since there is no color information)? I also noticed that when I start from a color photograph and then change it to black and white, the color sliders on the B&W adjustment can make a significant impact on the picture and i assume that is because the color information is there. Anyway, I am just curious about this and wonder if someone has a reasonable explanation. Thanks!
  2. Hi, thanks! Next time I run into this issue I'll see how I can send you a link to the image. Anyway, my question still is: Is the B&W adjustment supposed to have an effect on an original B&W photograph or does it work only if you are converting a color photo to B&W? And if it does have an effect on an original B&W photo, based on what is the effect operating (since there is no color information)?
  3. Hi, in the HSL Adjustment what is the function of the color spectrum bar above the Hue shift slider? Can you do something with it. I noticed that it does not change no matter what I do with the hue shift bar below it. Is it there just for reference? Thanks!
  4. Thank you Jack and RC-R. The explanation about the function of the upper hue bar really helps understand how to use the hue slider.
  5. Enjoyed all the videos! Seen them several times. Love the Affinity Photo. Looking forward to updates and new videos. Great job Affinity team!
  6. Hi, I noticed that when you use the High Pass Filter in AF there is an option for clicking on "monochrome". Is that used to desaturate the image before applying the HPF. In Photoshop, as far as I know, you have to use a Hue Saturation Adjustment to desaturate the image before applying the HPF. So, am I understanding correctly that by clicking on "monochrome" with the HPF I don't need to desaturate the image separately? Thanks!
  7. Thanks. So if I understand correctly then that is the same as completely desaturating the image. Right?
  8. Hi, I am beginning to understand how to use the Gradient Tool at this point but I am not clear as to the difference with the Gradient Map adjustment. When to use the later vs the former. It seems that the Gradient Map adjustment can be used to colorize an image (b&W or color) but what else can you do with it and when is it a better choice than the Gradient Tool. I have seen the 2 Affinity Photo videos on the Gradient Tool but there doesn't seem to be anything yet on the Gradient Map. Thanks!
  9. Thanks Matt. It is good information to know.
  10. What happens when you finish working on an image and you click on Share (for instance to Photo app)? Does Affinity flatten the image as a jpg? Sometimes, I don't need to save the image by using Save or Save as and I just want to add it to the Photo app on my Mac. But I wonder what does Affinity actually do with the image and can you control how the image is "shared"?
  11. I agree. I also find that being able to rearrange the adjustment layers list would be useful.
  12. Many thanks Madame and Darin! The giving a photo a vintage look video is quite helpful. I look forward to a more robust video in the future.
  13. Thank you Madame for the suggestions. I like the curve picker approach especially.
  14. Maybe this question has been covered somewhere else but I could not find it. Is there a way to combine several curve adjustments made to a single image (jpeg) in order to improve the dynamic range (HDR effect) of that image? in other words, in one adjustment, I optimize shadow detail, while in another curve adjustment, I optimize highlight detail, etc. I know you can try to do that with a single curve but sometimes, if there are a lot of small adjustments, it is easier to create several curves to address different tonal areas. I would like to know if there is a way to combine the adjustments so they don't cancel each other out? Or if there is another technique that I can use to obtain the same result with a single image. Thanks.
  15. Thanks for the tip Jack. You are right that by making an adjustment and then painting out the areas I do not want adjusted I can often get good results. What I am looking for is the best ways to improve the dynamic range of an image without resorting to external HDR plug-ins or software. I am not sure how making several snapshots would help achieve that result though? Maybe if Affinity eventually creates an HDR tool that would solve the problem. In the meantime . . . Alec
  16. Maybe this is not news, but I found out that instead of dodging and burning directly on the background layer, you can create a new pixel layer and use the paint brush (white or black) with varying degrees of opacity to dodge or burn (instead of using the dodge and burn tool). This way, the changes can be easily reversed or cancelled. Unfortunately, no amount of burning seems to make any difference on clipped highlights. I assume because there is no information whatsoever. Is the only solution to darken clipped highlights, to recolor them??
  17. Hi, I have tried unsuccessfully to use the "command + hide" to hide a selection within my affinity photo window and all I get is that the affinity application itself hides. I have tried reprogramming the command for hiding within affinity with other options but it does not work. I have even tried to reprogram the OS X command hide shortcut so it does not mean hide and I still can't make it work within affinity. I happen to use a hispanic keyboard and I have tried switching to an English keyboard layout and it doesn't work. Am I missing something? All I want to do is find a way to create a keyboard shortcut for hiding the current selection (for example, the selection brush tool within affinity when I need to). Any suggestions??
  18. I also found the video useful and I am wondering whether there is a way in Affinity Photo to have more than one layer window open at the same time like they have on the Lightroom video. For example, the Levels adjustment and the Contrast adjustment? That way you can tinker with both sets of adjustments in the same window without having to switch back and forth. Is there a way right now to do that??

    Cropping Tool : Darkening Non-Selected Areas

    I agree. I would like to see this feature as well. If it already exists and I am not aware of it, please let me know how to turn it on. Thanks.
  20. Hi, I have tried using the elliptical marquee tool to change eye colors but after I create the selections for both eyes, I am unable to reposition one of the selections independently of the other. They both move together. The reason being that I am not always able to draw both circles perfectly over the eyes, so I may have to reposition one of them slightly but not the other. I have tried several things but without success. Does anyone know how to do this? Thanks.
  21. I didn't realize I had started another thread, so I will look for the checker you mentioned. Thanks for your suggestions anyway. :)
