travel bug Posted March 30, 2018 Share Posted March 30, 2018 I am on Page 258 of the Affinity Photo Workbook and Paragraph 1 states Quote "Above the Background Dither Layer, create a new HSL adjustment by going to the Layer Menu and etc., etc. I do not see a 'Dither Layer' on the layers on this particular exercise and I do not know what Dither Layer is anyway. Can you help explain this Please. Thanks Quote Link to comment Share on other sites More sharing options...
Wosven Posted March 30, 2018 Share Posted March 30, 2018 Hi, "Background dither" is the name of a regular pixel layer on which he use the healing brush. Look at the Layer panel screenshot on page 259. Quote Link to comment Share on other sites More sharing options...
travel bug Posted March 30, 2018 Author Share Posted March 30, 2018 I was following the 'project' but didn't end up with a 'Background Dither' layer - must have stuffed up somewhere but what does 'Dither' mean?

AffinityJules Posted March 30, 2018 Share Posted March 30, 2018 The word "dither" means indecisive; hesitant; etc... Not too sure why this word was chosen to describe a layer, but I'm sure there's a perfectly good explanation for it. Quote Some scientists claim that hydrogen, because it is so plentiful, is the basic building block of the universe. I dispute that. I say there is more stupidity than hydrogen, and that is the basic building block of the universe. These are not my own words but I sure like this quote.

travel bug Posted March 31, 2018 Author Share Posted March 31, 2018 Thanks dutchshader and Psender for your reply. I think the best explanation for me (and I am still a bit confused even then) is the one from 'firstdefence'. The only time I remember 'dither' being used frequently was when I lived in England and people used to say 'I'm all in a dither' (being confused). I'm old and still learning....

travel bug Posted March 31, 2018 Author Share Posted March 31, 2018 Hi Affinity Jules, Yes that is the explanation I had for the word but not understanding its meaning in the photographic editing context. I sort of get a bit of it but still find it difficult to translate into how I would use this in editing on my photos. If I let it percolate in the old brain box for a bit I might get it eventually. At my age I'm expecting to lose some of my brain retention so we'll see how I go. Quote Link to comment Share on other sites More sharing options...

I will give an example. I used pavement around the house, and I had two types of tiles. I could connect them like this, but that would make a distinctive divide. So I used dithering, and the tile on the divider gradually mixed, so the transition is smooth. The same principle is used by color printers, which with several colors (depending on the number of cartridges/toners), can create their realistic looking colors by gradually mixing them. When editing photos, dithering is used if you need to reduce the number of colors - to avoid significant color transitions. For example, the Safe Dither Web will replace existing colors with only a few safe colors for viewing on the web. The image quality is still decent despite significant reduction. firstdefence 1 Quote Affinity Store (MSI/EXE): Affinity Suite (ADe, APh, APu) 2.4.0.2301 Dell OptiPlex 7060, i5-8500 3.00 GHz, 16 GB, Intel UHD Graphics 630, Dell P2417H 1920 x 1080, Windows 11 Pro, Version 23H2, Build 22631.3155.

Thanks for going the extra paragraphs for me. As *JC once exclaimed, "Alrighty Then!" I think I get it. So reducing colours doesn't give you a poorer result from a colour point of view? AND apart from helping web pages stop 'banding' is this used commonly for photographs? I haven't come across this before. I just looked up Web Safe Dither in Affinity Photo Help and up came the filter - Thanks for that I didn't realise it was there at all. Very interesting. *(Jim Carrey) Quote Link to comment Share on other sites More sharing options...

R C-R Posted April 1, 2018 Share Posted April 1, 2018 I am no expert on the subject but FWIW, it takes a great deal of skill to master a didgeridoo to produce the characteristic continuous drone (via circular rebreathing) & multiple resonance overtones the instrument is capable of producing. If you are interested in such things, check out the 'playing' & 'physics' sections of the Wikipedia article.

If you were asking me if I had redone that section of the book - I haven’t yet as I wanted to keep moving into the book. But I will go back to that exercise and redo it. I think it might be me missing the point but I will take more time redoing it and comment if it’s a problem in the book text. Thanks Quote Link to comment Share on other sites More sharing options...
