I'm having some 12"x15" bird photos printed for the Earth Day program, and to satisfy my curiosity, I sent to my lab a sharp, full frame capture for an experimental 24"x36" print!
This means that the old 20"x30" champions will now have to step down:
The crops are much better than the last 20"x30" I did, so I expect a spectacular 2 feet x 3 feet poster whose feather detail is decent even when viewed from 10" away.
40D + 500 f4 IS + Canon 1.4x TC, bean bag, resized full frame:
Crop from 10,800 x 7,200 pixel file ready for printing, 100% monitor view:
The above crop downressed to 96 ppi (my LCD's resolution) from 300 ppi.... this simulates how detail/sharpness will appear in print when viewed up close.
Processed 100% crop from native 3888 x 2592 pixel capture:
Some notes on large printing (20"x30" to 24"x36"):
1. The final 24"x36" (610 mm x 915 mm) poster was blown up from a sensor whose size is a microscopic 22.2 mm x 14.8 mm (40D). That's a scaling up of 41.2x in one dimension.... in other words, the final photo is 1699 times as large as the original capture in terms of area. Amazing technology!
2. To qualify for blowing up to this size, a capture should be pixel sharp, well-exposed and there should be absolutely no cropping,. You need all the pixels you can get to venture into medium format territory.
3. I always upres during RAW conversion so I can use the most capture info available. Upres size is the final dimension of the print in inches, multiplied by 300 ppi (pixels per inch).
4. I do not use NR on prints, as this kills fine detail and the noise grain can't be seen in the final print any way. Good prints look coarser/noisier at 100% monitor view than those intended for web display.
5. To simulate in your monitor how your print's detail will look, resize the file to the native ppi of your monitor using bicubic. For example, a 12"x15" file at 300 ppi will be resized to the same 12"x15" @ 96 ppi (my LCD's resolution). This means that your print's linear dimension will actually be only about 1/3 of the size displayed at 100% view in your monitor.
Will post a photo of the huge photo when Arnold comes back from my printer. ;D

I'm agoo-goo.
