    Crop problem


      I want to use a custom crop at 326x760 but LR change it to 8,5x20. Close but not the same. What to do?


      Running OS X 10.10.1 on an iMac 5K with Lightroom 5.7.1.


      Note: With the same version of OS X and Lightroom on a MacBook Air the crop is done right – exactly at 326x760. Running LR5.7.1 on Win81 the crop is done correct as well.

          I am guessing that you have 8.5x20 in your MRU list of user-defined custom crops. Decimally, this crop aspect ratio you are attempting is within the rounding limits of the Crop tool. You could try to enter in a few garbage Aspect Ratios into Lightroom's MRU list to chase the 8.5x20 out of the stack and then attempt to enter the 3.26x7.6 ratio.

            8.579x20 and 8.50x20 should NOT be within the rounding limits of the crop tool.  Why should the crop tool do this anyway. If you input a ratio Lr should just leave it displayed that way and not change it, especially when it does It when it is this far off.  What is wrong with displaying 800x1000 instead of a standard 8x10.

              The crop tool does not do pixels, it does proportions for its rectangle shape and decimal fractions with rounding for the actual start position and side lengths.  Yes, this is a royal pain in the a$$.


              If you want exact pixel dimensions, you need to specify that in the export dialog.

                If you reread my post I was talking about RATIOS, not pixels.  The ratio displayed should be whatever the user specifies, especially when the Lightroom ratio is this far off.  Some one at Adobe must think this is a great idea and I don't expect it to change.

                  Well, if the crop is being done right, I'd say count your blessings (sometimes they are off by one or more pixels), and keep a post-it note on your monitor:


                  326x760 = 8.5x20


                  I could speculate why crop ratios are simplified but it wouldn't change anything..


                  Personally, I'd like the ability to add notes to crop ratios, so one could put original wXh values and/or anything else that would help remind. Maybe when they expand the number of saved crop ratios..

                    Bob... where did you mention ratios??? You obviously have no idea how things work at Adobe... decisions are discussed and made by teams not individuals.

                    Using your logic you would like to have a ratio of 3.1415926535897932384626433832795028841971693993751058209749445923078164062862089986280348 253421170679821480865132823066470938446095505822317253594081284811174502841027019385211055 596446229489549303819644288109756659334461284756482337867831652712019091456485669234603486 10454326648213393607260249141273724587006606315588174881520920962829254091715364367892590360011330530548820466521384146951 941511609:1

                      326x760 (and 800x1000..) can be thought of as ratios. So the idea is to preserve as entered, rather than reducing to numeric expression with lowest values (and obliterating the user entered values from which derived). I don't think anybody is suggesting anything so ridiculous.


                      Don't get me wrong: I have a pretty good idea why Adobe simplifies crop ratios, but that doesn't mean it's always optimal for the user..

                        Maybe you should ALSO reread my post #2 where I specifically state RATIO.  Your example of decimal point accuracy is absurd when the OPs case the accuracy of the aspect ratio is WAY OFF when Lr redisplays it as 8.5x20.  Besides that, in my opinion this is a dumb design decision by Adobe no matter if it was made by one person or a group.  If you input RATIOS that have meaning to you such as 16x20 instead of 4x5 Lr shouldn't change it.  Take more time next time to actually read posts.

                          Bob, maybe you have not understanding of rations... 16x20 as you state is not a ratio, the ratio is 4:5.....

                          Of course I deliberately exaggerated just as you exaggerate by stating RATIO which is not in your post... but let's see what the OP has to say before we bore them with all the pedantics.

                            IN photography, 8x10 is an aspect ratio.  I realize it is not a mathematical ratio but we are in a Lightroom forum and I assumed people would understand what I meant.  It's still a dumb design decision which is what the OP is concerned about and I share his feelings on the subject. Instead of going off on tangents, could you provide a good reason why this should be considered a good design.

                              Bob, 8x10 is a format used in plate cameras and now for a print size which originated from the aforementioned.

                              The ratio for that is of course 4:5...


                              However back to the OP, I suggest you file a bug report at Photoshop.com as I don't see your issue on a retina MBP (brand new) so it may have to do with scaling on your 5K screen.

                                This problem has been discussed Ad Nauseam on several threads for several versions and Adobe probably does not consider it a bug so it would be a waste of the OPs time.  Rikk Flohr's post #1 I think is the correct answer on why it happens on one machine and not the other As has been discovered in other threads.  No more comments from me until new info is presented on the original problem.


                                i Would still like to know from anyone why this should be considered a good program design decision.

                                  Rikk - thanks for your answer. I forced 8.5x20 out of my MRU and the problem was solved for now. In general I don't think it's ok that LR snap a ration near an entered ratio. I only recognized the small change while the image did not fit into the design. Now I will look carefully every time I enter a custom ratio.


                                  I have found your articles "Holy Crop" during this issue. Interesting reeding :-)
