Adobe Creative Suite help--enlarging and smoothing an image

So I'm working on the figures for a research paper using Adobe creative suite, and I'm running into a problem. One of the images I have is sort of low-resolution, but I want to enlarge part of it to create an inset image. The result is all pixellated. Is there any way to smooth/anti-alias the image once it's been enlarged?

I'm a total photoshop novice, so any help is appreciated. I can't find a filter to do what I need...

Rasterize it.


Once it's enlarged, use the brush tool and blur the rough edges.

Woohoo! Better lucky than good, I always say... I was able to find a hi-res version of the image I was trying to enlarge, so the problem solved itself by being eliminated entirely.

Thanks to all for the help and advice, though. If your gall bladder ever acts up, let me know.

Go to the edit tab, the very bottom it says preferences. Roll over it and then click General. You will see a thing that says bicubic. Swich to bicubic softer. It help much. I made my avatar enlarged to a normal size pic with that.

There are 3rd party fractal-based resizing filters. They actually do quite a good job of enlarging an image without the large pixelated blocks.

trick is not to enlarge a photo, if you really really need to tho, anymore than 140% and you start noticing pixelation...(really that's ment to be 125% but you can get away with more). if i need to make a picture big cause i've no other option i'd tend to use the filters and do something with them, if that's not suitable i'll tell whoever to supply a decent photo or it's gonny look ****..


post the image and tell us what size you need it to be and we'll tell you if it's a lost cause or not.

Thanks, everyone--I have a very protective Principal Investigator, so I can't really post the pic that I need to work on. All the advice has been extremely helpful, though. I'll post the Medline citation if/when the paper gets accepted!

No, nothing to do with junk--zoomed-in images of healing wounds in genetically altered mice.
