Blow up photo.

[rmurdo]

Hi all, I have a photo from a pdf, if I blow it up, it looses quality.

Is there ANY way to touch this back up and make it look better?

Thanks,

Robert

Hi Robert... Welcome to RetouchPRO.

It all depends on the size/quality of the original and to what size you want to "blow it up."

There is speciality software like Genuine Fractals and Blowup that might help.

Questions:
1. What are the pixel dimensions of the touched-up original? (If you are using Photoshop, use Image > Image size to get width, height, resolution data.)
2. To what size would you like to enlarge it?

I have read that increasing the image size in 10% increments will assist with resizing

I find that if you resize in photoshop by adding 2% at a time and using the bicubic smoother option you can blow an image up without it getting too dirty (ie I did this with an 8x8 300 dpi image to a 24x24 300 dpi image and maintained a proffessional gallery quality image) It works surprisingly well.

I believed this for a long time myself, but not anymore. I read an article where a guy did comprehensive tests that illustrated "doing it all at once" is as good as incremental increases. I'll post the link if I can find it.

Also read that under the right conditions (decent original image size/resolution) bicubic smoother works as good as a plugin up to a point, so your point is valid, Revolver. (Welcome to RP, too.)

It comes down to the characteristics of the original image.

I recently bought the plug-in "blow up" from alien skin software. I was using genuine fractals, however, this ps plug-in does a much better job.

Hi the image is 83x60 and to make it even worse, I think it was a cut and paste from a pdf.

I'll try the ideas posted here.

Thanks all
