Can Slices be Saved at 300 PPI in CC?

Question

Hi all, I'm self-taught in everything I've done in Photoshop, but this is one that I haven't been able to figure out. I create a file at 300dpi. I often need to slice out part of it to save. (Like the front cover of a full-wrap book layout, for example.) But when I create the slice/s, and save for web it always changes the dpi to 72 and increases the # of inches to make up for it.

Main question: is there a way for me to slice out parts of an image, save them and have them keep the original size and DPI? Do I need to be using a different tool? I know I could work around this by creating a new file that is the right size and drag the layers to it and save that, but that seems like the long way around.

Any help appreciated!

Hi uglyfkj.glc ,

The idea of slices is that you chop up a photo, optimize different parts with different settings, then pull them back together as a table with html. The problem is that web layout with tables is obsolete. It's all divs now.

Are you heading toward Print or Web? I am guessing Print since you want 300 ppi.

If you only need one "slice" as for the front cover of a full-era book layout and don't need the html, you might crop. The slice tools are hidden behind the crop tool. You can crop with the crop tool OR the rectangle marquee tool.

I would use the rectangle marquee—either freeform or ratio (2:1, 1:1, 3:1, etc.) or fixed size (6"x4" or 4"x3", etc.) Make your selection. Then go to Image > Crop. Save as (not Save)!!!

DPI, by the way, is Dots Per Inch and refers to ink on paper.

PPI is Pixels Per Inch, which is how many pixels there are per inch.

DPI is meaningless on the web. Displays devices do not us ant DPI setting. They can not change their Pixel size the use the Pizels size they are manufactured with. You web Image will be seen at various sizes. Size depends on the Devices they are being display on. On the web you just care about the number of Pixels you save your images with, X number of pixel wide y number of pixels high. Save for Web does not save any DPI setting. If you open a save for web image in Photoshop. Photoshop will default its resolution to 72. You can change that to any setting you want the image to have. Un-check and set the DPI Print resolution you want. All that will change is the Image DPI print setting. Not a single Pixel will change. A Inch Unit is relative to resolution. DPI Resolution is Physical Print Pixel size.

300Px by 300 Px at 300DPI is 1" x 1"

300Px by 300 Px at 72 DPI is 4.167" x 4.167"

The Pixels are printed a different size
