What size prints can I do without any cropping, I use a K10d..

I find that printing 8"x10" crops the picture..

or can i do it in photoshop by cropping the whole print to 8x10

or am I just being thick ... I think I may have gotten a tad confused
Pentax K7 and K5 and several black tubey things with magnifying glass in that twist around and move in and out - to be honest I am not sure exactly what I have. Will list the proper names one day..

I hope that you're confused and I'm not! The ratio of our format is 3:2 long edge to short edge. Therefore using a 10" piece of paper I'd have thought the height would have to be about 6.7" thus wasting a lot of real estate.

Just to hijack the thread how on earth did we get stuck with 10x8 paper?

It gets cropped as an image from the K10D is a 3:2 ratio which will not fit in an 10x8 print (5:4 ratio). If you want the whole image you need to print 12x8 (or other 3:2 ratio paper size).

If your happy to loose 2 inches from the print you can do it yourself in PS - at least you would get to decide where it got cropped from.

edit - beaten to it my mikew!

If we are talking about inkjet prints then A4 would be a more likely size. If printed by a lab you could choose 12x8 inches, which is pretty close to full frame.

There is a choice. If you want the whole frame then you resize accordingly at 300ppi and accept that you will not fill some paper sizes. Just cut off the excess.

If you want to fill the paper use the Crop Tool and enter the size values in the top bar. When you crop, the image will be automatically resized and the image will be the same proportions as the paper.
Best regards, John

The reason harks back to the good old days of plate cameras etc, long before the arrival of even 35mm. You know what Imperial Standards are like, they never die

I wish more people would have imperial standards, the world would be a safer, happier place.
K20D and a substantial user manual to wade through

I thought it was probably down to plate cameras but why did they use 10x8 and 5x4?

The SI is metric though so if you Brits wouldn't be so stuborn and just use that everywhere it would be a lot safer

I've trully no idea why we got stuck with that size Mike, it isn't so handy

They've tried to get a serie that use a ratio of 3:2 called PA but it didn't worked. the system would be the same as the A serrie just like an A4 fits 2 times in an A3 paper.
These would be the sizes in mm
PA0 - 840 × 1120
PA1 - 560 × 840
PA2 - 420 × 560
PA3 - 280 × 420
PA4 - 210 × 280
PA5 - 140 × 210
PA6 - 105 × 140
PA7 - 70 × 105
PA8 - 52 × 70
PA9 - 35 × 52
PA10 - 26 × 35
Too bad right, it would have been so usefull...

to go back to the original post, here is a list of the sizes of photo paper link
It's handy that they did this 3:2(1.5) so the closer the number between the brackets is to 1.5 the better it will fit.

8 inch and 10 inch are probably sizes of rolls that the paper itself was made on. Full Plate was 8.5 inch x 6.5 inch and is given at the bottom of the page that Stefan has a link to. This was probably a standard size that they could easily produce from blown glass cylinders... unless they managed to produce flat glass in this size (unlikely in the mid 1800's).

I'd forgotten about full plate size.

Here we may have our answer 8x10. Quarto seems to be 10x8 although I didn't think it was but perhaps more importantly on the left edge copy draught is 20x16 which is probably where 10x8 and hence 5x4 came from.

Not say this which suggests Octavo is 8x5 one short step from 10x8.

Then again who knows it's just a link from the Internet.

Personally I like Octavo!
