  1. Thank you, that's the answer.
  2. To delete a snapshot in the snapshot panel - select the snapshot and click on the dustbin. When I do this the snapshot does not delete, am I doing something wrong?
  3. Thanks folks for bearing with me, my brain is still a bit addled with Photoshop. The solution has been in front of my eyes for some time it was just that the little grey cells were not functioning as they should. If/when the sampler moves away from one pixel to 3x3 I'll be ready to go.
  4. Unless I am doing something stupid two things happen. Frstly, when the picker is placed over the sampler and moved, the L reading for the sampler changes and you have to move the sampler in order for the small circle to appear on the curve which marks where the manipulation is needed. Secondly, the values read when the picker moves appear to be the values at the cursor as it moves within the curves adjustment layer.
  5. I asked about the sampler because I believe one pixel is not representative and that 3x3 or 5x5 pixels is what is needed. The object of the exercise is to change one zone to another, selected zone and this is done by changing the L value to another, predetermined value at the sampled point. Therefore, it is necessary to follow the change in L value that occurs when the curve is manipulated as demonstrated in the video.
  6. Having tried out the various ways of using the Info Palette I have a much better understanding than I had when I started. Do you know how many pixels the sampler reads? The last stage of the process which I am trying to emulate, has not yet been achieved. In the video, when the picker is used from the Curves Adjustment layer, a column of figures appears alongside the column generated by the sampler from the Info Palette. Thus, there are two identical columns of figures. When the curve is manipulated the L value from the picker changes following the movement, whilst that from the sampler is fixed. Without being able to read the L value from the curves adjustment the idea behind the zone adjustment process is no longer valid.
  7. Kirk, thank you very much indeed for such a lot of useful information. Next thing for me to do is to follow up your recommendations and learn about the tools available to me.
  8. Thanks, MEB for your comment. It is not about the zone system that I need help, but about how to use the tools in Affinity Photo to achieve the same result that Photoshop gives when using the Info Palette, Colour Sample tool and Curves adjustment layer. Using the information which you have already supplied the result is almost there but not quite and it would be good for Affinity Photo and me if the sequence could be completed.
  9. I wonder if someone would be kind enough to help me, please? The work flow I would like to copy is best described in a video by Ian Barber, which shows what I used to do in Photoshop and, having bought Affinity Photo and cancelled Photoshop, I now need to do in AP. The video is rather long but the process is described starting at just before the three minute mark and is completed at around 10 minutes. I am confident that using AP the rest of the process described can be completed. I am using Affinity Photo 1.5.3 on an iMac with the latest, up to date OS. The video is:-
  10. Thank you again, Alfred, I'll post it again in the correct place.
  11. Alfred you are correct, I bought the version on sale at the App Store on my iMac so tell me, please, where should I post my question?
  12. I wonder if someone would be kind enough to help me, please? I have been trying for 3 days to get an answer by twice posting my question into the appropriate forum and, so far, had no replies. Could this mean that my question has not been seen or that what I want to do cannot be done with Affinity Photo but only with Photoshop? That would be a pity as I have bought Affinity Photo and cancelled my payments for Photoshop. The work flow I would like to copy is best described in a video by Ian Barber, which shows what I used to do in Photoshop.

  13. I seem to be going round in circles and getting nowhere, please help. I started a thread yesterday on this topic and came to stoo because I was unable to explain exactly what I wanted. Well, here is a video using PS and I want to do the same using AP. It would be of enormous help if some knowledgeable person could spare a few minutes to look at how the lightness in a part of a black and white image is measured and stored in the info palette and altered to another value which also appears in the info palette. Once the change has been done I think I can manage the rest. https://www.youtube.com/watch?v=0byRKWZslRI
  14. Working on the belief that pictures speak louder than words the following video demonstrates what is done in PS and I would like to do in AP:- Unless you are interested in how the lightness value varies depending on which colour space you are working in my quest starts here which is about about 3 minutes after the start of the video and loading of the info panel. Once the change to the image has been demonstrated the rest I think I can manage.
  15. MEB, I must apologise but what I have been trying to do is not correct. The first part is fine up to the Curves adjustment layer so I am going back to the drawing board and, when I have sorted myself out, I'll be back.
