Why does this tool only allow a portrate shape crop? Shouldnt I be able to crop in any shape including landscape?

It does. Fixed aspect ratio, fixed size and normal. You have to select the Style and input the parameters.

In addition to the three choices pointed out by orussell, there is another option when using crop. After you select your rectangle, hover the mouse outside its corner. You'll see an indicator that looks like a curved, couble-ended arrow. You can now click & drag to rotate the crop.
The one shortcoming of the crop tool is that you can't simply enter an aspect ratio and let the dinension be whatever it winds up to be, like you can with the rectangular selection tool. With crop, you must specify actual dimensions. PS will reset the DPI (it doesn't resample, just recalculate the DPI) to correspond to the entered dimensions. You then need to open the image > resize dialog and reset the DPI, if it makes a difference to you.

What's is fixed size? I usually used fixed aspect ration (ex. 8x10) with an empty resolution. "Front Image" seems to be the same as digital zoom.

Thanks,

It will resample if you type a number into the resolution field.

Fixed size can be in inches, expressed as "xx in" in the boxes, in centimeters, expressed as "xx cm" ,millimeters "xx mm", pixels "xx px". xx denoting a numerical value followed by the measurement abbreviation.

Was not referring to opening the dialog and typing a number into the resolution field. Yes, PS will resample if the following two conditions are met:
1.) You check "resample"
2.) You change the number in the resolution field
If you are using the crop tool, and you set image dimensions of, let's say, 1 inch by 1 inch, then crop to 1000px by 1000px, the resolution will be reset by Photoshop to 1000ppi. The image remains 1000px square. Now, if desired, open the "resize" dialog, uncheck resample and change the resolution back to whatever you wanted.

Hmmm, that's what I do, but I considered that "fixed aspect ratio". Maybe I should ask what that is (fixed aspect ratio) instead?

If you have a number, a unit (like inches), and a resolution value all set, you will both crop and resample the image in one operation.

For example, if you set the crop tool to 4" x 6" @ 300ppi you will get a file which is 1200 x 1800 pixels, regardless of how large or small the original selection is. Be careful as you can easily upsample too much and mess up the detail.

In fix aspect ratio it is dimensionless, you can use any numerical ratio (within the parameters of the software) - 1.25 to 1, 1 to 2, 8 to 10, or whatever. The size of your selection can be varied by dragging your pointer to the opposite corner to where you start, much like in the "normal" style, except that the box is "constrained" to an aspect ratio. This is most helpful when you want to get as much info in a shot in a particular aspect ratio, ie. if you rotate a bit but you want to maintain the same crop as the original image but get the most out of it. Hope this helps. :)

In PS CS there is no option for fixed aspect ratio in the crop tool. That function exists only in the rectangular selection tool (which also can be used to crop). I believe that's a source of confusion here.

I think you are correct Fritz. The retangular selection tool is all I ever use for cropping.
 02/24/2005 11:48:09 AM · #13
In PS CS you can select the height and width with the crop tool. There's even a button to reverse the dimensions if you want to switch between portrait and landscape.

what version of photoshop are you using? in version 6 and 7 (not using cs so do not know) when you use the crop tool on your toolbar and to the right of the text fields where you type in the width and height. is a text field for resolution. you do not have to open up the image size dialog box.

We're going in circles here, LOL. Yes, if you set all three (width, height, resolution) on the crop tool menu, PS will do the resize and set the resolution at the same time, but that will result in resampling. If you want to constrain the aspect ratio, but avoid resampling or resetting the DPI, you're stuck. You need to "fudge" the dimensions, do the crop, and manually reset the DPI. If the image is destined for the web, the DPI doesn't matter, of course, but if the image is destined for print, or for insertion into a document, the DPI needs to be set considering the target.

yes we were but I think we were at the heart of the original question, if the original poster was in fact using the crop tool maybe they had information in the width and height fields and did not know that you could remove that information and thus had a fixed ratio of that dimension
