Odd issue with PS CS5 (actually its probably me but anyway)

Dara Robinson

So yea, hoping someone can help me and point out what ever it is that I am missing. I am finishing off a few digital things this week and stumbled into this issue.

So most of the printing I have been doing over the last year or so has been on A4 or A3 paper so I have been cropping everything in the proportions of 297x210 but never putting in px or cm or any ppi to ensure that I can have the proportions the way I want them without loosing any of the ppi or changing the image size in any way.
CS5 will not let me do this for some reason and I seem to have to put in some kind of specific measurement. Anyone know a way around this?

Up until recently I was using CS4 and everything was grand. I have had CS5 on the machine for a while now but for the last 5 months I have been working almost exclusively on film so not been using it much. hope someone can help me cause no idea why its happening on CS5 and never happened to me on CS4

I still dont get why I cant just use the crop tool without actually having it actually re-sampling the image size for me... before if I entered 297x210 (without px, mm, cm or something like that) it used to simply crop the image without changing the ppi or anything else on me. It would simply crop at that length and hight ratio

I'm not the best with the whole dpi/image size settings, I'm sure someone with more experience in printing will pop in but here's another article with responses that may or may not help:

The issue he is having deals with actually resizing the image, I'm actually looking to avoid that all together. I used to be able to simply type in 297x210 into crop and nothing else and it would leave the image resolution alone and simply crop within the proportions I gave it leaving rez alone. The net effect was a slightly smaller image but it was still at what ever resolution I left it at when I was working with it at the time.

I'm having a similar problem too - anytime I crop and image, no matter how large or small it is, it *ALWAYS* crops to 1800 x 1200.

It's a pain in the arse, so I just do my cropping in Camera Raw now.

I can't replicate the problem myself. I presume you've tried clicking the clear button when you select the crop tool? Maybe there is a value in the dpi box but it isn't rendering cos CS5 uses silly flash to render stuff now.

It doesn't mate My question is solely and exclusively to do with the crop tool. I get how re sampling works and how resizing and so on works. I was hoping someone would know if, and if so how, I could use the crop tool like before

Thanks though

You should have three boxes for typing in values in the crop tool, width, height, and resolution.
If you leave the resolution empty, it should do what you're trying to do.

Dara Robinson

Well the reason for the thread Heebie is that this is exactly what I am trying to do and it will not let me. Each time I try and enter, since CS5, width and height they now will not accept a value without it a cm, mm or px value and even though I leave resolution value empty when I actually crop it changes the size and resolution of my image

Right now I'm looking at an image of the following dimensions and resolution:

Width 24.38mm
Height 35.66mm
res: 3200dpi

If I set my crop tool to Width of 4" and Height of 6", and crop the image edge-to-edge and do the crop, I now have an image of 101.6mm x 152.4mm @ 739.5 pixels/inch.
My resolution is no longer 3200dpi, but the actual image data is unchanged. (except that the aspect ratio of the original wasn't identical, a slight bit was cropped off one end by the crop.)

It can't remain 3200dpi, because going from a 3/4" image to a 4" image would be a six-fold increase in the amount of data that makes up the image.

The same image cropped to 8x12 instead of 4x6 would have @370dpi resolution without changing the image data at all.
