Saving— (for Other Applications)

Q1:How do I make my graphics smaller for PowerPoint? I created a series of images for PowerPoint, but my slide show still seems slow. How can I make the files' size smaller without losing quality?
A1: Here's what affects the size of a file: physical dimension, resolution, and mode. Assuming the physical size is as small as possible, you then need to ensure the resolution is 72 ppi at the physical size you need in PowerPoint(i.e., don't save a 2-inch logo at 72 ppi and then make it three times bigger in PowerPoint). For onscreen presentations make sure your Photoshop image uses Indexed Color mode (Image>Mode). This will cut the file size down to a third of the size of an RGB file, but it should look just as good. Note: Indexed Color files do not print very well, so you'll have to choose between having the image look good onscreen or printing at a high quality. One option is to use File>Save for Web, because its “job” is to make file sizes very small while preserving the look of the image onscreen.
Q2:How do I put a graphic into PowerPoint so it appears as transparent on the background?
A2: First, press Command-A (PC: Control-A) to select your entire image, then press Command-Shift-J (PC: Control-Shift-J) to cut the image from the Background layer, putting it on its own layer. Then click on the Eye icon to hide the Background layer and lower the Fill (or Opacity) of the image layer to create its transparency. Go to File>Save As and choose PNG from the Format pop-up menu in the dialog. Now insert your image on your slide in PowerPoint (Insert>Picture), and its transparency will be preserved.
Q3:Is it possible to move a file from Windows to Mac? I need to take a file created in Photoshop for Windows and use it on my Mac (or vice versa). Will that present any problems?
A3: If the file is saved in PSD format, the only possible issue will be fonts, since there are some fonts that exist only on one platform or the other. At worst, you'll have to substitute the fonts on some Type layers. Other than that, there shouldn't be any problems. Note: There may be a slight but noticeable change in colors.
Q4:Is it possible to read annotations in any other program? I want to add a note to a document using the Notes tool (N). Can that note be read in anything other than Photoshop CS2?
A4: If you save as a PDF file, the note “should” be readable by Acrobat and the Acrobat Reader (I say “should” because older versions of Acrobat Reader might not recognize the note). Only PSD and PDF allow annotations to be saved with the document.
Q5:How do I save a Photoshop image to use in InDesign?
A5: InDesign will let you place many different formats, including PSD. It is one of the few programs that lets you place a layered PSD file without flattening it first. Generally, the decision as to which format to use will depend on your output method and/or advice from your printer. Note: InDesign CS2 also allows you to access and choose from layer comps in a PSD file.
Q6:How do I save Photoshop files to use in Illustrator?
A6: Illustrator will open and/or import a number of formats, including PSD, PDF, TIFF, JPEG, etc. In addition, you can export paths from Photoshop to open and edit in Illustrator. If you open PSD files in Illustrator, you'll have the option of converting the layers to objects that can be edited in Illustrator or flattening the layers. The option you choose depends upon whether you'll need to rework certain layers (i.e., Type layers) later on.
