I went into Michael's this evening to look at picture frames which the store near my house had 6 aisles devoted to.  Surprisingly they didn't have any frames in 8x12 or even in the 2:3 format which also includes 16x24 and 4x6.  Perplexed as I was, I headed over to the frames guy who proceeded to inform me that nobody shoots in 8x12 and that everyone wants 8x10.  So of course, I argued, informed him that he's "kind of an idiot" and walked away angry.

This leaves me in a bit of an odd spot though because I'm insistent that 2:3 is a better format to shoot in than 4:5 (8x12 vs. 8x10) as it gives you more of an image.  It's the same thing as viewing your a movie on a widescreen vs. a standard screen (the old TV's) and that's how I typically frame my shots for my clients.  Well, now my clients have a hard time getting a frame that allows them to show my work in the way it was intended.  That my friends is what we in America refer to as "no bueno".  

If anyone's having a hard time finding frames that fit, I've made a little list from Amazon of frames that are Amazon Prime (you can get free 2 day shipping and it's free to try for 30 days so if you don't have it get it for your order), inexpensive and most importantly, fit your photos.

4x6 Photo Frames on Amazon
8x12 Photo Frames
16x24 photo frames

The most important thing to us is that we're able to make it easy for our customers to be able to display their new artwork on their walls without experiencing the frustration that I did.  

If you know of any stores that have a supply of this size, please contact me directly or just post a comment and I'll be sure to update this list.
