I enjoy the detailed explanation of the different blend modes very much. Thank you for your effort. As for Color Dodge, I played around a little bit and the implementation in Affinity Photo seems to me to be somewhat unstable. Repeating Your experiments I expected to get a smooth transition of the shades. Instead I am getting a kind of salt and pepper pattern of only a view levels of grey. Furthermore the results a depending very much of the color format of the document. In the current state of the implementation neither Color Dodge nor Color Burn seem to be usable.
Difficult to comment without seeing where you are, Christoph. Factors that might be at play include dithering and bit depth. Dithering is random variation to create a 'natural' look, typically in gradients. I take RAW images then edit in 16 bit, which can make things seem smoother than if you use 8-bit. Also if you save and load via a compressed format, such as jpeg, the image will degrade on each cycle. And you can lose detail when you squeeze and stretch ranges via various adjustments.
In the video at about 5:00 you can see in the upper left corner of the square, what I mean. This might be a problem of the gradient, which is enhanced by the blend mode. If you change the document format from 16 bit to 32 bit (HDR) than the border between the white area and the darker area is no langer diagonal but is a curve making the white area much smaller. I tried the color dodge first on a HDR-photo and got weird artefacts. After converting to 16 bit the artefacts disappeared.
I think you are right in using the term geek when talking about this Dave.I do appreciate your really in-depth look into the various blending modes,however this does go over the heads of most people when is all they want to learn is how to edit photo's.You said some time ago you would look into the use of the Nik Collection,and it's uses when combined with AP. Do look forward to some more practical applications within AP,the recent videos by James Ritson and Olivio Sarikas are more in line with my editing knowledge.The Chris P Williams video was to me a very good insight into the use of the color panel,as I had never thought of C&P the hex codes from Adobe Color into AP.I will now as I can make quite a good range of swatches and gradients.
Fair comment, John. I originally qualified as an engineer, which I see as 'theory into practice' and this still informs my thinking. If you know what the electrons are doing, you can build any electronic circuit. I know it's not for all and I've also studied education, business, marketing and psychology, which also may perhaps be seen in some of my work. I still do 'geek' videos, partly because I enjoy doing them, partly because nobody else seems to be going into such detail (bit of marketing here) and also because there's nothing like trying to explain to others as a means of learning yourself. Of late, I've been applying my geekiness in building what I hope are useful macros (more to come!), which is one reason why videos are not daily at the moment (another is that I'm building a full index on the web for all videos, at the time of writing reaching number 498). Nik is on the list, as is iPad and another series for absolute beginners, plus of course continuing the blend mode series, tweaks and techniques, and 'full edits'.
@@inaffinityforaffinityphoto3220 GREAT Dave I am myself a highly qualified electronic and mechanical engineer now residing in Denmark (retired) having spent many years (initially for Marconi) developing systems for the wind powered industry.Retirement gave me the chance to empower my love for photography,inspired by my grand father who had a post war collection of german cameras (leica etc:).I now use all of that knowledge from the days of film to adjust to the digital world,so simplicity is my key word.My visit a few years ago to the media center in Bradford was a great experience.
John Collins The Chris P Williams video you’re referencing disappeared between my 1st watching and my attempt to view for the 2nd time (and save). Have you run into the same issue?
