As an audio engineer, I'm dithering the master output because of mp3 releases and mp3 files are 16-bit maximum. But if I choose a 24-bit FLAC file as an output option, I don't have to apply dithering the right away. This dithering is similar to it because both of them apply noise and make them seamless in lower quality formats.
it's kinda the same because they are both "DAC" of some sorts, one convert visual color informations to binary files that represent the chosen color, the other convert analog generated soundwaves to binary files that contain the sound, and this digital file format can't be precise to the exxxxxxxxxxxxtra 0.0000001 decimal if you don't give it enough space to be :), hence stepping effect like banding in colors or aliasing for sound as it's commonly called.
ikr? Sad that mp3 codec "lame" do not save all of dithering frequencies (Lame don't save 20k+ Hz), so you should convert to mp3 thru iTunes software. But iTunes codec sometimes messes with the phase of track. Lame codec doing it less. A double-edged sword innit
@@AlexdeJesusRit's the same thing happening in this photoshop video but with Audio files The dithering is the final step we do before exporting in lossy formats.
Unless, this is just a comment in general. I really like your teaching style. It is straightforward and linear. You always explain what you are doing and why. Some of the lessons are so full of information it can really go by fast, but you never fail to deliver the what, why and how. Thanks!
This is hands-down one of my favourite of your short tutorials to date and I now have a new appreciation for dither! I just love your teaching style, Unmesh! ☺
Worth noting for anyone that finds they can never get rid of banding it could be that their monitor is actually the issue. Monitors with a low dynamic range can't handle gradients very well. You can find monitor tests online to check this, or send your design to another device to see if the banding is present. Increasing image size to 300 DPI and adding a layer of grain will also help.
This is my way of avoiding the bands.. After making the gradient, I'll just converted into smart object then goto camera raw filter. Reduce noise from noise option. Then add some noise from effect option.
If you're blurring an existing smart object and are having issues with banding it always helps to add a Scatter layer filter on top of your gaussian blur, that will add a similar dithering effect and will work on any image inside the smart object!
Nah I don’t care about clout, just have a weird edge-case I use it for and a shit memory It’s called Spatter, my bad. It’s under Filter>Filter Gallery>Brush Strokes>Spatter.
Your Filter Gallery might be greyed out. If so it’s probably because your document isn’t 8 Bits/Channel. You can change this in Image>Mode. For some reason adobe’s filter gallery effects won’t work in any other amount o bits.
Thanks this is actually extremely useful as I take a lot of concert photography and stage lights created tons of circular banding situations on the pictures and this may just improve my work!!
I always used to provide edited images with replaced spotlight backdrops... some customers complained more than others, I guess in proportion to the quality of their screen... anyway, now I always use gaussian noise on top, that way I have a LOT more control over how it looks. Also that noise makes for a far more pleasing overall image than the dither.
Dont forget to set: ✅ Enable "Display 30 bit" (Ctrl+K/Settings/Performance/Advanced). ✅ Enable "Smooth 8bit gradients" (Ctrl+shift+K) ✅ Get a 10bit cappable monitor and set the color accuracy to RGB/Full/10Bits at Nvidia control panel.
Oh hey thanks for showing setting to turn it back to classic gradient! I typically don't use gradient masks in Photoshop and I was super annoyed with this update having to make tons of unnecessary layers just for one gradient effect.
I always watch your videos and learn a lot from you. Thanks for your sharing. Can I request all of your videos to post on my channel in Cambodia? Because I want to share your teachings with the people of my country.
Interesting. However, I have the issue in an image where the background happens to be a graduation between one shade and another (i.e. it is a gradient, but not one I created), therefore dither is not available to me. Any suggestions?
does the bit per channel change apply for images that will be used for ecommerce? I believe that 8 bits per channel is the standard, but I am no expert
When I'm working with a text that has dropped shadows or outer glows etc, everything is perfect. But once i wanna save/export/merge/flatten it, the shadows become malformed and ugly. I've tried everything and nothing fixes it. Any idea what might cause it?
