what is the ratio that i can type in for a crop using the crop tool in photoshop for an 8 inch by 10 inch crop.

i can type in 8 x 10 inches but i want to crop to a raio (for 8x10) not the actual measurement.

thanks,
joe

This probably seems like a bit of a silly question when it is first read, but if you leave the crop tool's resolution setting blank in PS, it will simply crop the image w/o physically resizing it. It will set the image's dpi (resolution) to whatever is needed to mathematically say it is the chosen 8x10 inches at the cropped number of pixels.

You could also use the rectangle selection tool & set its Style to Fixed Aspect Ratio or Fixed Size, but I prefer the crop tool due to it being easier to resize the selection wonce you start it.

If that is what you wanted...

Joe - I use the "calculator" thats on my computer as part of the programs. Set it on your task bar ready to use.

For crop and keeping 8.5" x 11" ratio is 1.29 : 1. Keep this ratio when you crop and you will always maintain the proper ratio.

Joe, I understand what you are asking, as it is a question I have asked without getting a satisfactory answer. In both PS and PSE, I find no way to set a ratio. If you put 4:5 with no DPI, you get 4x5 pixels, and so on. If you put a print size, like 8x10 or 11X14, the crop tool gives you a resampled result.

FWIW, I also use Paint Shop Pro 8. With this program, when you use the rectangular selection tool, you get an indicator on the lower right part of the screen showing the currently selected area in pixels and the aspect ratio. So when you know what you are looking for--1.25 for 10x8, 1.33 for 4:3, and so on--you just drag until the number shows. Then you can click the "crop to selection" tool, and you are done.

Down side of PSP in this function, though, is that you cannot resize or move the rectangle once it is drawn. You have to start over.

Oh well, no perfect program, eh?

See my other post on this topic -- put in your crop size in inches, not pixels, and leave the resolution setting blank. In most cases, ther will be no resampling -- the dpi setting of the resultant image will be recalculated, though. I believe thre might be situation where resampling occurs anyway, but don't remember the details of that.

Not true. In Elements, just as in Photoshop, if you put in 4 in one box and 5 in the other with nothing in the Resolution box, the program automatically adds inches to your numbers - you end up with 4" x 5" with no interpolation. The only way Elements will go to 4x5 pixels is if you put 4 px and 5 px in the boxes.

You can check this by cropping a photo using 4 and 5 - then going to Image> Resize. You'll see that your photo is now 4" x 5" and the resolution is quite high. In this Image Size box, you can also change the 4 to 8 or the 5 to 10 to get an 8x10 photo - and see what the resolution is going to be for the 8x10; if you check the Resample box (which I wouldn't do here unless I were sending the photo out to be printed), be sure to put in the resolution you want to end up with in the Resolution box.

Personally, if I were cropping a photo in either Adobe program, I would crop it for the paper size I'm using; if 8x10, that's what I'd use. That way, if I print from the program using Print Preview or Print with Preview, I can set up my printer and paper size and use Scale to Fit Media with very little change in my photo size (only enough to make it fit on one page). If I were going to interpolate using the program, this is where I would do it.

Not true. It does that for you, because you have your units set to use inches. If you enter no units, those crop width/height settings use what your PS sytem is set to use as default units. Try turning on the rulers for an image, change the display to pixels & try entering 4 and 5... you will get pixels.

Okay, I'll go along with that. I should have said at default settings .
