45ish MB. Nothing fancy or extreme, just a little b/w restoration. All the (free) editors that I normally use say “No mas!” when I try to edit it. I’m guessing that there are purchased editors that can do it with no problem, but I’d be purchasing a ton of options that I don’t need (but that’s the way life can be sometimes).
Adobe Photoshop Elements offers a free trialfor 30 days. I’m pretty sure it’s fully functional, and that it will be able to handle your file. Then if you like it, it’s about $80 to buy. You probably don’t need all the stuff in the full version of Photoshop, but it has a free trial, too.
Does it need to be big after you are finished? If not try nonags.com for something to reduce it first.
Have you tried paint.net?
The GIMP should easily handle it.
Second Paint.NET.
I’ve dealt with files that big in it before, and no problems. It’ll use less memory to handle it, since it only does RGB and not CMYK (like Photoshop and Photoshop Elements) do, so it might actually be more “efficient” for this task than Photoshop or it’s little brother. On the other hand, Photoshop is designed and tested to handle images of hundreds of megabytes, so there’s that.
Of course expect pixel-by-pixel operations to be slow-- there’s no getting around that no matter what image editor you use.
Restoration? Do you mean photo restoration in the commonly understood manner, i.e., taking a damaged picture and recreating the missing / damaged parts from the other parts of it or from other pictures entirely? For that you will probably need a software capable of cloning, healing, layers, masks, color-matching, and more.
If you mean you just want to process some B&W pictures, then Photoshop trial and PS Elements trial will work; or Paint.net, GIMP, FastStone Image Viewer, Irfanview (all free). Possibly Photoshop Online also.
As free processing software goes, I highly recommend FastStone. Great little program and not too complicated to learn. It’s also an excellent viewer program.
If you have the Microsoft Office suite on your computer, you should have Microsoft Office Picture Manager. You can open the picture in that, make a copy, then reduce it down to a manageable size using the Resize command.
