hey when you zoom in on a picture it gets all pixelated

is there any filter or proggie that cleans the pic up even when zoomed in
like a fuzzy logic proggie or sumthing

<think tv programs that zoom in on faces and the computer can pull out the details and show a face instead of a bunch of blocky pixels> sorta

Yeah, its called blur...

Don't expect it to look better though. There is nothing that that will let you get more image data then what you already have.

There are, however, various functions that can enhance the picture in other ways other then resolution, but which ones will actually help your image rather then degrade it all depends on what your starting with and what you want to get out of it. If you give a better idea of what your trying to do I can be more help. Regardless though to get any image enhancement your going to have to do some playing around with some different techniques, there is no single make better picture function.

say i have a person in a picture i was hoping to be able to zoom in a bit closer and then somehow clean up the image so it is no longer jagged and pixelated but still have detail

something that takes all the pixels and i guess averages them out maybe?

like say i wanted to zoom in on a nose and have it still look like a nose even zoomed in and not all blocky

i just figured there was a filter or add on or stand alone proggie that would allow me to do that

i'm tired and can't think of how to describe what i want to do

A blur filter is the best you can really do with out editing the picture yourself. You may get slightly better results if resize the picture to twice its size then blur it, but your going to lose detail with any blur. A blur is averaging the surrounding pixels around each pixel to get a new value for it.

Theres about a million different ways you can do this averaging with different weights to use for each pixel when averaging it and different numbers of surrounding pixels, but in the end they all sacrifice detail for smoothness, theres just no way around it.

In photoshop, for what you want to do, youll probably get the best results with just the regular blur or smart blur, but play around and see the results. To get anything better you will have to edit the image yourself, the computer can't do this since it doesnt understand what the picture is actually of and just can't create data that would make the image look more like a nose then it is already like you can.

the reason it gets pixilated when you zoom is cause thats just how the picture is setup.. a blur won't make the pixils any smaller. You'd have to increase the dpi of the picture.. but you could always zoom in to the point where you'll see pixils

smart blur or unsharpen mask

for much better results, use a program like Genuine Fractals.

oddcomp · 02-17-2004, 08:21 PM

that fractal thing is prolly what i need but i can't see paying 145 or whatever it was for one or 2 times i might use it

hmmm

robiewp · 02-17-2004, 08:24 PM

I'd just take another picture. genuine fractals is pretty good- in my opinion what you get is like film grain. You don't get any more definition, but it's not as noticable to the naked eye (most things in nature don't occure in pixels).
