Photoshop Resampling plugins

Does anyone know of Photoshop resampling plug-ins to get
large 300 dpi documents out of 3.5r2?

A pixel is a pixel is a pixel.

First know the print size you want like an 8 x 10 or whatever your print size will be. Then multiply the number of inches by the print resolution you want. For an 8 x 10 at 300 dpi you would need a 2400 x 3000 pixel render. There are some good plugins for Photoshop but it is always better to render at the size you need in the first place. Since you should render at "AA Half" in ZBrush to avoid the huge wait times for antialiasing settings too high, an 8 x 10 would actually need to be an 4800 x 6000 render. For a plug in list go to the Photoshop site at Adobe. The good ones cost a little and do better than the default in PS but none can get you the same quality as before resampling. You always loose some detail no matter what they tell you. You can get good results though if you don't go beyond a 50% to 100% increase in size. To see for yourself download demo's of the plug-ins and try them first. They are not a magic pill. Genuine Fractals is one many use. [http://www.ononesoftware.com/](http://www.ononesoftware.com/)

One from Alien Skin I’ve never tried that looks promising called Blow Up.

Blaine, Thanks so much for the reply. I like to work at
42" x 42", usually at 600 dpi (or ppi) but this is not doable
so if I could do 300 that would be very helpful. That means
12,600 by 12,600. Is this remotely possible from ZBrush?

hi Corinne,

just to verify, i tried a max. resolution of 8k inside zb3.5… when trying to render zb crashed or “stopped working” (microsoft slang…)

anyway, why do you need a resolution of 600dpi on 42"? i can imagine you are used (and like) to work in photoshop… but to be honest: THIS IS PURE OVERKILL!!

eg.: you want to print your image on a semi-decent largeformat printer like a designjet from hewlettpackard… ok, these printers “support” 600dpi and more… but only internally. means they use a dotpattern based on a dpi setting like 600dpi… this is already enough for a finearts photopaper. ever heard of TOO MUCH INK on the paper?

solution: if you don’t own the printer yourself, please ask your printservice person to do a few testprints with resolution settings startin at 72!!!dpi. going up to 150dpi or maybe 200dpi… you’ll be surprised what kind of quality you’ll get from 72dpi! photoquality, anyone?

of course, if you like to combine typography with your image, make sure to provide a pdf, eps or ps-file inlcuding your fonts NOT rastered but as postscript outline - they should appear crisp, right? (same goes for vectorart)

ever seen one of this mega-large-blowup images hanging on building walls?
ever thought about 600dpi?! hahaha! you’ll drop dead on the spot when you’ll hear about 20 or even 15dpi!!!

cheers! and stay away from 600dpi for your lfp-service provider! they will hate you! :wink: (processing time to rip a 600dpi image at 42" wide by height is expensive - most likely the lfp-operator will lower your image resolution in photoshop before rip-process without telling you…)

chem!

Chem: Thanks. I generally don’t work on paper, but rather
on plexi and aluminum. I will have them make test strips
for me at several resolutions and see what happens. But I
think a key will be what comes out of ZB (3.52r). I have
succeeded with Max, but only with carefully programmed
rendering.
