Aspect ratio of 10x8 and 5x4?
Hi all,
Quick question, I’m using a 35mm dslr and iPad to do lighting tests before using my large format cameras.
Obviously the frame proportion is different on the 35mm dslr so I wanted to set the cropping function on my camera/iPad.
Could someone please let me know the aspect ratio of 10x8 and 5x4 (I imagine they’re both the same??). I’ve tried 3:4 and 4:5 and both look promising but it’d be good to know which is correct. Thanks

Uh, 4:5...
Think about it...

Thanks for providing probably the most unhelpful reply I’ve received it several years of using this forum!
Let’s hope someone with some useful and informative feedback replies...

Danny, the definition of aspect ratio just is the proportion between height and width (or width and height, you can specify it either way so long as you're clear about which approach you're using and whether you're talking about horizontal or vertical orientation). So by definition, the aspect ratio of 4x5 is 4:5, and 8x10 is 8:10, which is the same thing as 4:5.

Actually, I answered your question, and in fact was rather restrained in my post. I could've been derisive, but I was not.

My Nikon D800 had 5:4 aspect ratio crop available.
I sold that camera, perhaps other Nikons have it, my D750 does not and I miss it.

how about reducing it down - an aspect ratio of 1:1.25
it's pretty close to a square 1:1 ratio
Re: Aspect ratio of 10x8 and 5x4?
Look at the image opening of your film holders and divide the length by the width. For 4x5 it’s about 1.266 (4.75 / 3.75) and I think 8x10 is about the same border size so just slightly lower at 1.258. Both are close enough to 5/4 or 1.25 that you probably should just use that.
Re: Aspect ratio of 10x8 and 5x4?
Calm down folks. This is not as straightforward of a question as you might think - both 4x5 and 8x10 have dead areas on the borders due to how film holders work, this could easily change the aspect ratio (it just so happens that it doesn't).

Funny, this has reminded me that long ago in NY I asked to a B&H seller for a 4x5 camera. He seriously looked at me and said: "Hmmm, I don't understand you... What is a 4x5 camera? Maybe you want to mean a 5x4 (emphasis) camera, isn't it???"
In the US, people name it this way, while in e.g., Europe, many people used to call them a 9x12 camera (note the smaller side first) most of the times followed by a tag line, "... well... or 4x5 (small side first) which is the same thing" (which obviously is not!).
(Excuse me... I'm going over old times once again... :D)
