>>2210781 how can I do it on photoshop?
>>2210781just tried it in GIMP idk which one is better tho
>>2210835second pic
>>2210971
man, I wish it was easier to choose the palette on gimp rather than just automatically do it
Here's an attempt
Dithered version of an Asuka one I was using. Stole the logo for >>2211395
What exactly do I need to do in Gimp to achieve this?
>>2211440I use Image > Mode > Indexed
Making these is fun!
>>2211489eww furry
I just realized the last 2 I posted were 1-bit. Oops!
no changes, just 2 bit
auto-levelled first, gives it more contrast and the grey is now blue, still 2 bit
PaintNET just lets you save in 2-bit. It's neat.
>>2212916Effects / Color / Quantize lets you have more control over the number of colours as well.
>>2212909what is auto-level?
can someone add 2 bit depth to this? T.I.A
I'd be glad if anybody could lend me a hand and let me know how can I make these pictures look better. GIMP btw!
>>2214810for one get rid of lolis in your PC
>>2214810for two create custom palette to control colors
>>2214199hello anon, what color background do you want
>>2214873i don't know anon, i think the original color is fine but if it doesn't work out i'd love to see what you come up with. :)
>>2214874same anon here, didn't realize that it was actually a jpeg. tried out pngquant since i have no idea how to do it with gimp and here's what came out of it
>>2214874disregard >>2214882 i just realized that 2 bit meant 4 colors and not 2
>>2214883this looks seriously cool, thanks anon. is it hard to do with gimp? t. someone who has 0 experience with it
>>2214884No problem anon. I used pngquant to make it as I can't get the hang of gimp
>>2214884Same anon here don't mind >>2215009 I figured it out and it's fairly easy. Just open up the image you want to process in gimp and then press "Image" in the menu bar and select "mode" and then "indexed". Then choose generate optimum color palette and set it to 4 for 2-bit and then press generate.
Not anime but I liked
>>2215081cringe
>>2215081great wallpaper anon
>>2214882what series is she from? looks good thanks for the pape
did some on a whim and I like how they turned out 1/3
>>2215778
>>22157793/3
Tried doing it in photoshop, but not sure how many colors to use. This one is 16 colors, and any less just destroys the darks like an old NES game.Are there more effects I need to apply to get that old PC98 game feel?
>>2215797Your dithered Dracula is not dithered enough.
Tried it out a little bit
>>2216020Alternate after further experimentation
this is cool im gonna make more of these
>>2214883>2 bit meant 4 colors and not 2noted
First attempt
>>2216579
I tried making a few
>>2216667
>>2216668Last one
>>2216721
for the gimpbros, do you guys use positioned or floyd-steinberg?
>>2216924Floyd produces ugly stripes. It might be better with larger palettes, but I always use positioned for 2b
did a few more in gimp1/3
>>22169672/3
>>2216967>>22169683/3the rest are too shitty to share
Pretty nice, I've always add a little noise to wallpaper since I loved the way they looked. This could be even better, but I think not every wp would be fit. Gonna try to reproduce with some of mine, and see how they end.>>2211442 this is the way?
Anything else to take into account in gimp aside of doing the indexing with 4 colors and changing the dithering algorithm? Is there any other parameter I can set?
>>2217195play around with the palette to get better colours if you'd like (windows > dockable dialogs > colormaps)
>>2217408Whats the point of posting nonexisting resolutions in 2b thread? The 4 colors will end up interpolated
having fun with this so i'll throw in a couple

>>2222382But it is nice when it works.I'll try something in a more wallpaper friendly resolution next.
>>2210794Yeah, found your source pic, gave it a try.Wasn't great.I'll maybe try manually cheating the algorithm a little bit.

>>2222416My eyes hurt but good effort Idk my fav maybe the third
>>2222429Good taste. There's enough edge-based colors for the tree detail to be there.It would be my fav except I'm not fond of what it does to the slime's human form hair / slime form in general.

>>2222591>>2222592FYI, 4 colors are picked from a palette of 64, which come from having just 2 bits per R,G,B channel. Think EGA.It is intended to support ECS chipset's special modes (productivity / super hires and other custom), which use full Agnus DMA at 4 colors, and a special denise mode that tolerates that which has 2 bits instead of usual 4 depth per channel.This is why there's such blatant color changes.OTOH it also means there'll be a lot of pixels of the same color at a given line, which makes the popcnt palette picking strategy work.
Miyako
am fat and lazy, please proceed to show me how to re create such things.
This is my first time doing this and I don't know if I'm doing it right.
>>2222693yohane a cute.Looks nice, but you only used one bit depth.You had 4 available.
>>2222696My bad, I forgot that 2-bit doesn't equate to 2 colours. I guess lacking sleep does that to you.This should be fine now, right?also yes, yohane a cute.
>>2222709Indeed, that's 2bit proper.yoshiko rhimes with oshikko.
>>2222768>oshikko is peeing in japaneseThat was a good one anon, you deserve 2 idols for the price of one image.I'd pee myself too if I was the 2nd most popular idol in Aquors.
>>2222779Ironically, riko also rhimes with.While I like them all, my faves are dia and kanan.
>>2222796You have good taste anon.They were also my faves back then but as I got to know yoshiko and riko more, I gradually found myself liking them more than dia and kanan.
>>2222808You do, too.Gave this dia the crude 4color / line treatment.
>>2222826You should make dark red darker to get more detail from shadows.Also please, post real resolutions, why do you post 5109x7271?
>>2222841How do you do the 4 colours per line thing? I followed >>2211442 and it didn't really give me a lot of options to play with. Nice dia btw, way better than mine.>>2222857My bad sorry, it won't happen again.
>>2222903>How do you do the 4 colours per line thing?It's a from-scratch custom implementation by myself. It is still crap; not ready for general public's eyes.I don't think I've seen any other implementations in the wild.The target is a special Amiga video mode, so called "productivity mode", available with ECS denise. A500+/A600/A3000.It allows a mode with interlaced-like resolution but progressive. It uses double the bus bandwidth, so it occupies full DMA bandwidth with just 4 colors, thus the palette cannot be changed during raster, only during dead margion areas / blanking.Due to limitations with the DAC, only 6bit RGB is available, so the 4 colors are chosen among 64.
>>2222905So you wrote something that emulates productivity mode? I can barely look up information pertaining to it without being thrown into an old forum/website.So productivity mode is to make way for larger resolutions at the cost of colour depth and you managed to take advantage of its limitations to make wallpapers? sounds pretty cool anon, keep it up.
zero two in 2 bits
>>2222391>>2222395how do you create these aesthetic line glitches?
>>2223167See >>2222905
>>2223167Or if you mean your kurisu, it's a type of dithering whether even/odd lines dither/not.It is a relatively common strategy. I believe I've seen it used in HAM_converter, somebody's implementation of amiga image conversion fuckery.

>>2210818>>2224290>Save for Web or in newer versions export save for web (legacy)If you want to do some editing afterwards, it's image -> mode -> index then make sure to change "forced" to nothing. Afterwards you can use mode -> color table to change colors. Photoshop gets really pissy and laggy when you start jumping between dithering patterns though.

>>2237354Distorted version
I really like the source image from this one, however, even with high dithering, the girl's hand and part of her outline are seldom visible. Weird.By the way, I think most of these wallpapers would have looked better with low/no dithering.

this is 4-bit depth rather than 2-bit because the latter looked like shit
>>2222935>>2223167Yup, I did. Productivity mode is easy, and I also have HAM.The hard part is to actually convert images to these formats. I came up with a bunch of algorithms, but I'm far from done.I should get back to it at some point.The main thing is the copper allows changing colors mid-raster (if not using full DMA) and during horiz blanking.Taking advantage of that, dynamic hires, dynamic ham (often called SHAM or sliced ham) are possible.But actually cleverly using this and dithering to get the best image possible is hard.
awesome thread
just did this one literally 2 minutes ago
