is there a way to make 35mm slides from digital files without having to print a large copy and photographing it? I'm trying to put together a 35 mm slide portfolio.

Any help would be greatly appreciated!
Thank you

I came close to doing that once for my portfolio. There are some printing places that do it, the same kind of places that can print your digital images in high-quality, or large format prints. Anyway, I would look in your local yellow pages, start calling up printing places and ask if they have that service. I had luck doing it this way [i can't imagine any other], and some places that didn't have kind of printing even referred me to others that did.

A forewarning though.. it's kind of expensive. I'm not sure how pricey, but more so than a digital print for sure.

I had to do this in art school....have slides made from digital files. I believe I did it a a Copy Cop. I brought them a floppy with my files on them and they output them to slides. I have the slides somewhere.....I never got to see them projected though...

Yep. Clients, contests and catalogs still want slides sometimes. I use a number of different photo-process places to do this for me. Look'em up in the telephone yellow pages. I usually pay $6 - $12 apiece, but it's been awhile since I've needed to do this.
My experience may be different than yours, but I've been asked to make them RGB tiff files 4096 x 2732 pixels (1:1-1/2 ratio). That's normally no problem for me since I work at about that size anyway. If your pictures aren't that large or are square or long or other odd dimensions you can enlarge a bit and sharpen, or increase your canvas/picture size in the odd/smaller dimension and fill with black.
It's also good to give your pictures a small black border anyway so they don't get the edges cut off some weird way when they get mounted in the slides.

Good luck.
