Sizing page and resolution


I know that when I use my photoshop it takes my 3502 x 2336 jpeg and shows it low resolution of 72....I know change the resolution to what you want to print at and it "shrinks" file to appropriate size..... if I put in a preferred size ...let's say 20 x 30 inches it will formulate and let me know what the resolution will be for that "file"......HERE IS MY QUESTION?
- I want to push this up alittle... ..there are three boxes...Scale Style Constraints..... and Resample WHAT ARE THEY SUPPOSE TO BE SET AT AND HOW DO I PUSH THE SIZE UP (RESOLUTION) UP A LITTLE AND WHAT ARE THOSE THREE BOXES SUPPOSED TO BE CHECKED , AND HOW ON EACH BOX. THANKS...DARYL

doug Nelson   When the resolution (density of the pixels, in pixels per inch) shows up as 72, the dimensions in Image Size are probably huge. UNcheck Resample and leave Constraint checked. Now enter a common print size, in the long dimension, such as 10 for an 8 x 10. Photoshop will calculate the other dimension AND the res for you.

You will notice that the image on the screen does not shrink at all. That means the file size remains the same. NO pixels are being discarded, they're just being spread out more.

Push the file size up ONLY if the long dimension of the print size you want causes Photoshop to calculate less than about 240 as the resolution. What's this magical 240 number? Its the INPUT resolution most inkjets prefer going in. If you come up short on the res, THEN check Resample and, leaving the desired dimensions set, bump the res up by 10% in increments.

If you get into the habit of shooting at your highest available resolution, you will get file sizes that can handle all but the biggest poster size prints, or a print from a severely cropped part of the image. You should rarely, if ever, need this Resample tapdance.
