Crop tool interpolates?

I need some basic understanding of the crop tool in CS. It seems to interpolate when I crop. How to you tell the thing to crop at 100%?

Also I would love to know for doing web images how I can specify say 800×600 pixels and be presented with a rectangle at that size and ratio ready to crop at 100%.

When I crop in ACR at least I know it’s a 100% crop, and I will painstakingly resize the crop window until I see the required dimensions in the info window before I move it to the position I want.

I hope I’m just over thinking this but not sure what is going on!

Thanks for your tips and tricks on this.

Hi Bob

On the task bar (when the crop tool is opened) simply fill the wanted info into the width Height and Resolution blocks.

what he said
select crop tool
in boxes at the top
leave resolution blank if you do not want resampling to occur fill in 800×600 in the dimensions boxes MAKE SURE TO WRITE IN PX NOT INCHES or your comp will freeze up

you can save that setting to your presets in the tools to use over and over

Hi, First, thanks for your help.

Can you tell me what the step is after your last one? If you want me to drag a box across the image, that is not what I want to do because it will resize the image when I accept the crop.

For years I have done exactly as you describe and the result is the still the same: The crop tool still allows me to drag and resize the crop box when instead it should be locked at 800×600 pixels. Typing in W 800px H 600px seems to only control the ratio, not the size of the crop box. I hope that makes sense.

Here is my workflow:

I open an image at say 3000×2000 pixels

I choose the Crop tool off the toolbar

In the Width box I type 800px

In the Height box I type 600px

I clear the field for Resolution

At this point I would like a crop box at 800×600 to automatically appear on the screen so I can move it around the image to the desired location. But instead it seems my only option is to drag a box across the image which forces a resize.

Many thanks for trying to help me understand this.

Hi Dave,

Thanks for the reply. It still is not working how I want. If you have a moment to see my reply in this thread to Katwoman I hope my description helps you understand my confusion.

What puzzles me is in ACR the crop tool seems to give me a true 100% crop, that is, a crop without resize. It’s still a pain to use but it works: I set the values for the Crop tool in ACR to be the ratio I desire and then when I drag a box and release the mouse, I can look at the info window and see the size. Then I just keep moving the corners of the crop box very carefully to make the box smaller or larger until I have a box at exactly 800×600. Then when I convert from RAW to CS3 I have my perfect, "100% crop" at 800×600.

But I know there has got to be a better way, and I cannot even do this in CS. I’ve actually converted JPEG to DNG so I can use the crop tool in ACR.

I don’t think you can do that directly. Try choosing Marquee and opening Info (Window/Info) and and drag a box to give your 800×600 pixels in Info measurements. Make sure your rulers are in pixels first. Then you can drag the marquee around to where you want it.

But, I don’t see why you would want to do it that way, as it means you cannot choose the composition of the crop and resize it for web use.

The crop tool does resample, and for web use I set the dimensions to 800 x 533 (3:2 crop) and 72 ppi, compose and frame the area I want, and it’s done.

Hi Colin. That’s perfect! I only wish I had the equivalent feature in ACR.

Thank you,

Nope. Won’t work.

When you type 800 and 600 in the Crop tool settings, you are telling Photoshop: "I want to drag a box with the crop tool. Then I want you to crop where I drag. After you crop, I want you to resize to 800 pixels by 600 pixels."

But that isn’t what you want. You want a fixed box that is 800 pixels by 600 pixels. In order to do that, you will use the Marquee tool, not the Crop tool. Here is how:

Step 1: Click the Marquee tool.
Step 2: In the Options bar, choose Fixed Size. For Width and Height, choose 800 px and 600 px.
Step 3: Click in your picture and hold down the mouse button. You will see a fixed size 800×600 box appear. Keep holding down the mouse button and drag it wherever you like.
Step 4: Click on the Edit menu and choose Crop.

Perfect. I had no idea you when you use the crop tool you must resample.

You don’t have to; if you leave the width, height, and resolution fields blank, it won’t resample. But it won’t crop to a fixed size, either. For that, you use the Marquee. 🙂

Hmm,. I dont see how you can have one without the other…

For
that, you use the Marquee. 🙂

Definitely!

When I say it won’t crop to a fixed size, what I mean is that it crops to whatever size the mouse is dragged to–it doesn’t crop to a pre-specified size. The size of the resulting image is interactive and set by the user when she drags out the corner of the crop handles.

Yes, that makes sense. Thanks again.
