Best way to make a poster of this pic? Thanks!

Hi everybody. I have a couple of quick questions.

I got a call from her grandmother asking for me to print a "poster sized, black and white print" of her individual gymnastics pic. (This is just a downloaded thumb...full-size is at home on my PC)

I don't have the image on my work computer, but have some specs. The image size is 2304x3456, but I will want to crop a little bit.

Can I crop this at home, upload it onto Mpix (where I do most of my printing) and have a decent poster? Will they upsize or anything, or will it print at like 100 dpi? Should I try uping the ppi and resample and all that? Also is 20x30 considered "poster size", or is 16x20, 16x24, 20x24 ok?

Thanks so much!

After cropping, you'll want to do some upsizing in PS. Make sure you use bicubic smoothing when resizing. Best practice used to be to upsize in 10% increments, but I don't know that this is necessary anymore. There is also some excellent dedicated software that does a good upsampling job, but I can't remember the name just now...

You could rasterbate .

Thanks for the responses. I think I read somewhere that 10% was needed prior to Photoshop CS. I am using PS7 at home. I also thought I read that if you upload the full sized image to Mpix, they would do inhouse upsizing to get you to 20x30 at a decent dpi. Has anyone else heard this?

Genuine Fractals is what I was trying to think of.

You can't create detail out of thin air, despite what you see on TV, but at least a poster isn't usually meant to be pixel (dot?) peeped. Sizing it to 300dpi at the print size can't hurt, though. I wouldn't worry about the increment thing, but you can try it and see if it really makes any difference...

The thumb I posted is just a sample to show how much I would want to crop from the picture. Like I said, the full sized image is 2304x3456, but at 20x30" that is 115.2 dpi. I guess I was more looking to see if people took shots from their 8MP cameras, did NOT upsize, loaded them onto a print site and got decent posters from them.
