Cropping to an actual ratio

    Of course, it won’t crop

    No, but canvas size will. You could try that. I’m not much help on the other problem but I have found in the past that any crop I did would crop to 1 pixel unless I cleared the values. Then it went away and I don’t know how that happened so I can’t be of any use.

    Photoshop CS.

    I mentioned that in my first post thingy.
    Maybe it’s a bug they got rid of in later versions?

    OK.. well that’s a pretty old version of Photoshop so I would disregard the Height/Width advice as this probably only applies to CS2 and CS3.

    Yeah I know… I can’t afford CS2 or CS3 so I’m still using CS.

    I wonder if anyone else out there still using CS has this happen them when they use it?

    nfl – I’m not sure that the “this” is that you refer to:
    “this is CS3 maybe CS2 also.”

    I think you mean the tutorial that Peter did is for CS2 and CS3 users?

    Thanks everyone for trying to help me anyway.

    What should work is the Rectangular Marque Tool and select the option or style “Fixed Aspect Ratio”. Then go to “Image” > “Crop”.

    I presume you haven’t yet tried my suggestion of using the rectangular marquee tool yet?

    I think there’s really one one foolproof, safe, tried & tested solution:

    Sorry about that Thorsten –
    what with all the suggestions coming my way I didn’t get a chance but I did it just now and that works perfectly!

    Thank you (AGAIN!) so, so much.
    You’re turning out to be my guardian angel of help and advice on here!!!

    No need for the apologies :wink: I think we are all prone to suffering from information overload and sometimes we stubbornly stick at something which isn’t working for us because we know IT SHOULD work and then forget to look for other solutions. One of the big strengths with Photoshop is also one of it’s biggest failings, in my opinion. There are usually several ways of reaching the same outcome and it’s not always immediately clear which is the best for a particular usage. I’ve often done things one way and when somebody showed me a different way of doing it have been known to say “Oh sh*t, now why didn’t I do that before”. :wink:

    If you set a ratio in the crop tool, it will indeed set the resolution to a very high number with a document size of 1×1.5 in, or cm, or whatever unit you have set as the default.

    To correct this, simply go into the Image Size tool and change the resolution to whatever you want to print at (300ppi or similar). Make sure the ‘resample image’ checkbox is turned off and Bob’s your uncle. Sorry if my tutorial caused confusion, I’ll make a note of this problem on the page.

    Here is what the Image Size tool looks like when you go into it after cropping your image to 1×1.5.

    Here, I turned off ‘Resample Image’ and set the Resolution to 300 ppi. Note the pixel dimensions are the same as before, and the print size is now a more reasonable 24x37cm (this will vary with the size of your own image!)

    There is an easy way,
    if you’re cropping to the same proportion as the original,
    which is quite likely, if you’re looking for 1:1.5 (2:3) or thereabouts, from a 1.5 crop dslr-

    Use the crop tool,
    and select the whole image-

    Select a control point, and re-size while holding down the shift key-
    it will maintain the proportion of your original selection-

    thanks again for the help everyone.
    I think Thorsten’s suggestion is proving to be the simplest one as I can select a particular area and crop out the rest rather than just reduce the image or canvas size.

    Still… at least now I know of a bunch of ways to get around my problem – thanks!

    also Peter… thank you for confirming that I’m not just going crazy that that this is what Photoshop actually does to an image when it’s cropped the way I was doing it!

    Okay..I’ve been reading this thread ..and it has me just a little confused (not hard I’ll grant you).

    I’ve always used the same method as above for cropping and never noticed anything when I got images printed. I don’t do my own printing, so maybe that’s it.

    But I did what pihjin described and when I checked the copy image it did indeed have an image size of 3cm x 2 cm (the ratio I cropped too).

    Does this mean that I am losing image quality when I print?

    Just a tad confused now :shock:

    expresbro –
    No, you’re not losing any quality. When you crop as above, photoshop sets the image size to whatever you enter into the crop tool. The number of pixels in the image remains the same, however. It just crams all the pixels in the image into that small space, hence the resolution of 7000+ pixels per inch.

    Printing is all about taking the pixels you have and spreading them out on the page in a useful manner. As mentioned above, it’s all about how close the image is going to be viewed. If you print your images at 50 pixels per inch, you will get some very big prints but up close they will look awful, because for every inch of print area there are just 50 pixels.

    If you print your image at 300 pixels per inch then you will get smaller images that look better close up (more pixels per inch). If you print at 7000+ pixels per inch, then you get a tiny image that has super detail when seen close up.

    In your case, your printers just open the image size tool and change the resolution to a more realistic number (say 300 pixels per inch) which increases the printed dimensions without changing the image content in any way. If they then need to make the image larger (upsampling) to print bigger, they will do that, but that would be necessary regardless of what we’re talking about here.

    Cheers,
    Peter

    Okay..so I..and I presume most of the others..can just leave well enough alone then? Panic over ;-)

    Thanks Peter

    This is how I do it if the ratio is the same as the original.
