Peter Branch Posted July 12, 2014 Share #1 Posted July 12, 2014 Advertisement (gone after registration) Am I alone in wishing that the new feature of Crop Marks In Live View had included marks to define the view cropped to conform to the 1:1.414 ratio of A4, A3,......? In my view an oversight whose correction would be very welcome. Link to post Share on other sites More sharing options...

Peter Branch Posted July 13, 2014 Author Share #4 Posted July 13, 2014 Looking for people to join my campaign to have foolscap crop marks. Anyone? I was not aware that Digital Ink Jet papers were available in Foolscap - are there any? Plenty of paper available in A6, A5, A4, A3 & A2. I understand the 16:9 crop marks but what exactly are the others for? Link to post Share on other sites More sharing options...
JohnJWhite Posted July 13, 2014 Share #5 Posted July 13, 2014 I understand the 16:9 crop marks but what exactly are the others for? 1:1 replicates the 6x6 or 2 ¼ square format, most commonly used by Hasselblad and Rollieflex. 6x7 replicates the slightly longer 6x7 format used in many medium format film cameras like the Pentax. 4x3 is the old television format, and I believe is also commonly used in point&shoot digital cameras. I'm surprised they didn't include a 4x5 format, not that I would have used it. Link to post Share on other sites More sharing options...
01af Posted July 14, 2014 Share #6 Posted July 14, 2014 6:7 replicates the slightly longer 6 × 7 cm format used in many medium format film cameras like the Pentax 67. No, it doesn't. "6 × 7 cm" is this format's nominal size but the true size is closer to 56 × 72 mm. That's a ratio of 7:9. So the inclusion of 6:7 crop marks is nothing but foolish. 4:3 is the old television format, and I believe is also commonly used in point-and-shoot digital cameras. ... as well as in almost any pro-grade camera that isn't 35 mm, APS-C, 6 × 6, or 6 × 7. In particular, virtually all digital medium-format cameras and backs sport a 3:4 format (except Leica S). So do the four-thirds digital cameras. I'm surprised they didn't include a 4:5 format ... So am I. 4:5 and 5:7 are frequently-used paper formats and sheet film formats used in view cameras, while 6:7 is totally useless. Also, 5:7 is equal to 1:1.4 which is very close to 1:1.41421. So I'd vote for ditching the dumb 6:7 marks and including 4:5 and 5:7 instead. Link to post Share on other sites More sharing options...

What's the significance of the ratio 16:9? 16.18:10 I'd understand (golden section). Link to post Share on other sites More sharing options...
JohnJWhite Posted July 14, 2014 Share #8 Posted July 14, 2014 What's the significance of the ratio 16:9? 16.18:10 I'd understand (golden section). 16:9 is the current HD television standard. At least it is here in the US. Link to post Share on other sites More sharing options...
Peter Branch Posted July 14, 2014 Author Share #9 Posted July 14, 2014 I think 01af is correct. I can see no point in having marks that indicate the sensor formats, (film or digital), of other cameras, some of them obsolescent. 5:7 is a printing ratio which, I suggest, is what really matters. It's a size much used by high street photo printers and is so close to the A4 etc. ratio as to be indistinguishable in practice. There may well be a few other useful printing ratios in addition to 16:9 which is required to meet HD TV standards. Link to post Share on other sites More sharing options...
Rick Posted July 15, 2014 Share #10 Posted July 15, 2014 What's the significance of the ratio 16:9? 16.18:10 I'd understand (golden section). It is the aspect ratio that was requested by video users in order to pre-frame video in LV before pressing the M button. I assume Leica just threw in the other ratios because they could. I think it is cool and I might use the square, others not so much. Link to post Share on other sites More sharing options...
