</3 Gradient Banding

It has been brought to my attention how nasty my vector looked under JPG. It's utterly disgusting. If I were an anime character, a waterfall of vomit would come out of my mouth. Good news is that I fixed it earlier this morning.

Big difference am'right? I usually churn out 1,100+ gradients on vectors I spend about a month on. I am so thorough with my gradients because I know they add up in the end. Melting every highlight and shading of the character to my desires :D~. Although it makes me sad when I look back at my works and it doesn't completely reflect all the time I spent on it.

It gets difficult when banding occurs because I can't accurately see ****and it looks nasty. I have many methods of getting rid of banding that worked in the past. However with Yakumo they didn't work.

I explored and found another method because my usual means did not work. I would place my 16-bit .psd into AI and it says it has to convert it into 8-bit. Whatever! Anything to eliminate banding. After placing it I had to upscale it back to the original size. There is no more visible banding and everything is still crisp.

The pain of using PS but it's the only program I am comfortable with in shortcuts and interface. AI is a foreign language to me because Adobe thought it would be funny having different pen shortcuts between two similar programs.

I know how to use Inkscape but I am not totally comfortable with it. So I vector slow as ****in it lol. It also pisses me off when I try to hit a shortcut and it's typing in the add layer column (or whatever it is). It's like WTF! So I am always bashing the ESC key in rage. In 0.48 you can't pan anymore with the "edit paths by node" tool selected anymore. So it's just rage layered upon rage and I don't feel like opening IS. =___=

Friggin' balls.

Gradient artifacting/banding/whatever sucks ass terribly. D8 Most notably on dark colors. Using higher bit colors helps (for some reason on my ps, 32 bit is always grayed out ;___; I wish I could select it to see how it compares) and using textures helps too. Interesting to see that AI would not have bands when you tried... I've used some layered gradients in AI and saw some bands before, so not sure what you did different, except upscaling it. O.o

Haha I also don't like some of AI's pen shortcuts. I press one key and I get a permanent black arrow when I wanted the white one. ARG Also I like how my tablet in ps has a hotkey for the hand tool to drag the image around. Doesn't work at all in AI. XP Hate using the sliders to scroll the image.

Also, you use ps to vector and add gradients, so do you use the layer style gradient overlay on your shape layers, normal gradients in vector masks, or something else?

OMFG.

Seriously! I usually get banding when I try to make a subtle gradient in darker areas. Need moar shades of gray.

Sometimes I notice a difference between 16-bit and 32-bit. Most of the time the gradient bands get lighter and have more bands in them. I still like to work in 16-bit. In 32-bit you pretty much lose almost all layer effects and filters (ie: no soft light). Here is a comparison of 16/32-bit linework I did over a year ago on an old WIP to show my friend.

For my gradients, I use gradient overlays on the shape layers. I set the fill to 0% and leave the opacity at 100%. I like the overlays because I can always go back to move them around and they scale up/down according to the shape's area. Thus... they're vector-like. :D

Yeah, just adding more layers of "pigment" helps lessen those bands. @.@

Interesting, in your gif it seems the 32 one has more anti-aliasing and thinner lines. O.o But lawl no wonder I can't select 32 bit on my stuff, I abuse layer effects and blending modes. :D (Hmm actually, even on a new document in ps, I can't select 32 bit, even under image>mode on a blank document - do you need to select a certain color profile for it to work? ...Or perhaps a 64 bit machine, still using good ol' XP.)

Can you believe it, I use 8 bit most of the time, including on my Saito wall...otherwise the psd file sizes might kill my computer. For me, if there are any obvious bands, I gaussian blur the finished png in select areas. There weren't many on Saito though, fortunately, and plus the cloth texture covered up whatever bands that might have been in the dark areas. Once I get a new desktop instead of this 5 year old laptop, I'll be able to handle the 16 bit files! 8D w00t

Ah, I thought so. :3 Somehow only able to have a select number of gradient types (ie linear, radial) would make shading uniquely shaped objects tricky, imo (why I'd just paint it in). I guess that's why you use a ton of them - they all add up! @.@ Best to you on your upcoming wall! :D

I have no idea why you can't select 32-bit.

All I know is that if you have a mask selected it will blot out all the options. Not sure if other layer types have similar behavior. When I go from 8/16-bit to 32-bit, it just warns me about the effects will be discarded and if I want to flatten everything. Maybe graphics processor doesn't support it? I dunno. :/

It kind of sucks making unique gradients. I have to use folders and pile up 100% opacity gradients and then reduce the opacity of the folder. 99.9% of the time I don't need to do that though. The gradients pile up like crazy and shoot up my layer count. I create quite a few folders to help sort out everything lol.

Thanks! I'll probably start working on it a bit this weekend. :D

I have a good nvidia graphics card, so I don't think that's it. More likely because I have an older operating system. I want to get a new desktop anyway. 8D

Blergh sounds complicated. @.@ Props to you for figuring it all out and making it look so nice. :D Layer count must be insane. I usually get around 400-500, with a few merged ones so that the file size doesn't kill my computer. Or I make separate psds - I used two for Saito. The second one had all his layer groups merged so that I could work on the bg.

Good luck on the wall! Really looking forward to it. X3
