I am using CS5 - answer will be the same no matter what, though.

I am going to composite a number of images. Each one is, of course, huge. I have made copies and am going to be working with the copies. How do I resize? Just changing the resolution or the dimensions doesn't do it as the other just goes up and I still have a huge file. I think it's because I don't have "resample" checked - but I don't know. And if I should have "resample" checked, what about the other options I will then have to choose from (I think) like bicubic?

I don't need to understand though if you have a simple explanation that would help me remember this in the future in a logical way that would be great. For now, I just need to get these things down so I can put a bunch together.

Oh, and the new file I will be putting them together in, how large should that be? I don't expect this to turn out great, but say it should and I want a print that's 18x24, for example. What then?

Weather's crummy here today so I'm trying to work away - so appreciate the time of whoever answers :)

I'm using CS4 but I think you change the file size by going to "save as" select jpeg and ok. A box will open with a slider where you can adjust the size of the file. It will tell you the file size on the right hand size.

I hope that's what you were asking...

With your document open in CS5 click
Image menu, pick Image Size
You must pick your Resolution first
set Pixel Dimensions second
pick the Resample method you want last

After you've clicked OK, click the magnifying glass tool, then in the menu at the top pick Actual Pixels & take a critical look at it.

Create a new document in the size you want, then you can copy/paste the individual images in each on its own layer.

In a document that's 18x24 in., if each photo was 6x6 in. you could have 3 across & 4 down, with no borders. It's easiest if all the images are the same size. But you also have to take into consideration that all the images should have the same look as far as color saturation, black intensity, etc. They should look like they belong together.

If it's going to be printed, it'd be a good idea to find out what resolution their print process requires, & do that. Otherwise they have to resize for you, & you may not like the result.

It's actually a lot of fun after you get your routine worked out

Thanks
This is what I need to know but it just doesn't work that way for me. I go to Image Size. Pick resolution. Then Pixel Dimensions. At that point the Resolution goes through the roof. I think I need to check the "resample" box first or it won't let me do the other. But then my question is which resample method do I want?

If Resample is not checked, then Pixel Dimensions can't be changed by you at all.

The resample method you pick depends on whether you're downsizing or upsizing.

or

once you pick your resolution, you can pick document size & let pixel dimensions be whatever. This would be for printing on paper. Pick the resolution the print process requires, pick document size you require, pick resample method that gives the best quality.

Some people ignore all that & just resize by click-n-dragging, after you paste the image in.

This works better if you are making a collage with variously-sized and cropped pictures. Batch resizing is better if you are making an array of standard-sized pictures.

As you note, checking the "Resample" box needs to be done, but it can (must) be between the steps in either order:

In the Image Size dialog with the "Resample" box unchecked:
-Set resolution (image dimensions will change)
-Check "Resample" box
-Set desired dimensions (Resolution setting should not change)

OR

In the Image Size dialog with the "Resample" box unchecked:
-Set desired dimensions (image resolution will change)
-Check "Resample" box
-Set resolution (dimension setting should not change)

You can chose the desired resampling algorithm from the drop-down menu at any point before you execute the transformation.

ok
I'm forging ahead. Probably be a mess anyway LOL Checking the resample box allowed me to change stuff and I now have small images to work with. Thanks all
