Compositing

I was practicing compositing and have a question about that. I was using a stock image with a resolution of 72. The image I took has a resolution of 300. Should I change something here or just continue?

Your best bet is to have both images at the same resolution.

More important are the pixel dimensions. You can have the same file of 2000x2500 pixels be high resolution at one size and low resolution at another. It’s an 8x10 at 250 PPI, and a 16x20 at 125 PPI, and a 32x40 at 62.5 PPI.
The resolution means nothing without knowing either X by Y (H and V) dimensions in pixels or inches.
Pixels are just numbers in a file. They represent color and brightness. You can reproduce them at any size you want, within the capabilities of your printer or display. So... be sure the sizes you are compositing are compatible at the resolution you need to use.

Same a chain link. The strength of it depends on its weakest link.
Same goes with anything we do with photography and or post processing.

As Bill said, image "resolution" is a number that is saved in metadata to indicate how big a print you'll get at a given dpi. You can save your 300 dpi image at 72, and absolutely nothing will change, unless you resample the image.
The best thing you can do is import the stock file as see how it looks. If the scale is too small, you likely don't have enough pixels in your stock image, and you'll need to use something better.

If you use Photoshop, you can open your smaller image as a smart object, and that will enable you to resize, if needed, without it getting all "pixalated". I've made composites like this for scrap booking and it works fine. I don't know the science behind it, but, give it a try. Just remember to OPEN the image as a smart object. It doesn't work if you change it after you open it.

As long as the paper stock is biodegradable, you should have no probl.... "compositing" not "composting", Never mind.
