Introduction to Large Format

[manonthedollar]

Wow, that was beautiful video with incredible dynamic range. What did you shoot that on?

I need to shoot large format. I live in Derby, so I'll try and come to one of these if you do another.

If you want a place with no comment length restriction - try my blog where I've discussed resolution before.. just google "timparkin large-format-resolution"

I agre that this is the maximum theoretical.. However this is with microfiche black and white film using a leica lens. If you are using a standard transparency or print film, you lose quite a bit. However, if you are comparing it with a digital camera (where they cheat by saying 20Mp when in fact it's a distributed across bayer array pixels) then you can boost your count by 2-3.. I'd say that for texture/lines 4x5 is equiv to 150Mp, for colour texture 3-400Mp

Here's the math. (This is consistent with what the lab who drums scans my E5 film says.) A good quality 35mm slide exposed with a good lens has the equivalent of about 22-24 MP. Multiply that times 13.3 to arrive at the MP for 4x5" and you get just under 300MP. But the number I see published frequently is 250MP. Do a search for ZoneIII. That's me. Great video! Keep it up!

Well done! I believe you may be wrong about your 100MP statement, though. I believe it's closer to 250- 300MP. I'm a long-time large format photographer myself and you may want to check out some of my darkroom videos. Look for ZoneIII. Anyway, my understanding is that the a good 4x5" film holds the equivalent of about 250-300MP of information. I was going to do the math her but I don't have space. Best.

Beautiful video, well shot. Good luck!

Thanks Paul! It was fun - we might do an organised one next time :-)
