help with shrinking

[Lunchbox7985]

maybe a little backwards from what youre used to. but a lot of people here seem to have a lot of experience with photoshop (or gimp).

i have some premade 175x160 covers for my ds. and then i have a much larger pictures that i download and shrink to 175x160. (because i dont have premade ones for a particular game)

if i got to Image > scale image, and type in the size, its really pixelated. i can blur it a bit and it helps.

or if i use the scale tool and click and hold the down button to dial it down gradually, then it ends up a bit smmother but blurry, i can use the sharpen tool and help that out.

the latter yeilds better results, but neither seems to get as good of results as the ones that i have downloaded in the correct size. alas i dont know who made them so i cant ask them.

i also have to shrink my ps2 covers down relativly small for the program i run on it (called open ps2 loader) and i run into similar problems.

so any possible advice on maintaining a good quality pic when shrinking it so small?

mario was in the cover pack that i downloaded, whereas scribblenauts was one that i took a normal sized pic and shrunk.





thanks

Above this there is image that for some reason might not be visible as medifire is acting up.
it should pop up eventually.

hit quote for dl link.

but to answer your question it's the DPI that probably screws you.

When you shrink something, only so much information can be stored.  So when you shrink something, it trys to recreate the image the best it can, but for example the images below, you remove 694 Pixels X 578 Pixels.  Each image is different, as if there is a bunch of detail in the image, its not going to scale properly =\

206 Pixels X 172 Pixels


VS

900 pixels X 750 Pixels

And this is exactly why I always tell people to NOT scan at 600DPI. You're supposed to scan at the resolution in which you plan to work with and print, and everything I've seen here is 300dpi (or 72, with crazy weird file pixel dimensions).

if you change the size keep the resolution at 300 and that should keep the pixelation down

Depends on how one processes, filters and cleans an image. Everyone has different methods. If 600 dpi doesn't work for you, that's you. All my scans for TCP start at 1200 dpi and end at 300 dpi. I personally have a harder time working with scans at 300 dpi. Unless someone is personally scanning for you, let's keep the recommendation to 600 dpi.

i actually found something online about different "methods" when you scale an image, by default is uses one called cubic, but there were some other options, one of them (forget which) yielded much better results.

still not as good as the covers i had downloaded in that pack, but a little blur tool, and a couple filters later and they are close enough. you can still tell a little on a computer, but once you load them to the DS, you cant tell at all, and thats all i cared about.
