Q: I edit in Photoshop, for Photo Books.  Should I use CMYK or RBG?  8 bits or 16?

I edit in Photoshop for my IPhoto books.  Should I use CMYK or RBG for best color?  8 bits, 16, or 32?

    Use RGB and JPEG as the format. As for the bit bit I use Photoshop CS3 and don't see where to select those options.

    8 bits, 16, or 32?

    Use the bit rate that your original photos have. There is nothing be gained by blowing up the bitrate beyond the photmetric resolution your original photos are having. Are you shooting your photos as jpeg, raw, or tiff? If your original photos are jpegs, stay with 8 bit, and also, if the original raw or tiff files are 8 bit  formats,  don't blow up the file size by switching to 16 bit.

    sRGB JPEGs for the best reaults -  generally you will get the best results by editing in iPhoto rather than PhotoShop - the book printing is  designed around  consumer point and shoot cameras using iPhoto editing - getting fancy y produces apooresults in many cases

    I am much more proficient in Photoshop (CS5) than IPhoto.  I understand it is important not to get too technical, but Photoshop gives me a range of brightness or black point for correcting parts of a photo that are unavailable in IPhoto.  Thanks for the info on sRGB.  Makes perfect sense.

    This may be preaching to the choir but here are some tips on using PS or PSE from within iPhoto as the external editor:

     

    Using Photoshop or Photoshop Elements as Your Editor of Choice in iPhoto.

     

    1 - select Photoshop or Photoshop Elememts as your editor of choice in iPhoto's General Preference Section's under the "Edit photo:" menu.

    2 - double click on the thumbnail in iPhoto to open it in Photoshop.  When you're finished editing click on the Save button. If you immediately get the JPEG Options window make your selection (Baseline standard seems to be the most compatible jpeg format) and click on the OK button. Your done. 

     

    3 - however, if you get the navigation window

    iPPSsave.PNG

     

    that indicates that  PS wants to save it as a PS formatted file.  You'll need to either select JPEG from the menu and save (top image) or click on the desktop in the Navigation window (bottom image) and save it to the desktop for importing as a new photo.

     

    This method will let iPhoto know that the photo has been editied and will update the thumbnail file to reflect the edit..

     

    NOTE: With Photoshop Elements  the Saving File preferences should be configured as shown:

    I also suggest the Maximize PSD File Compatabilty be set to Always.  In PSE’s General preference pane set the Color Picker to Apple as shown:

    PSE9genprefs.PNG

     

    Note 1: screenshots are from PSE 10

     

    Note:  to switch between iPhoto and PS or PSE as the editor of choice Control (right)-click on the thumbnail and select either Edit in iPhoto or Edit in External Editor from the contextual menu. If you use iPhoto to edit more than PSE re-select iPhoto in the iPhoto General preference pane. Then iPhoto will be the default editor and you can use the contextual menu to select PSE for your editor when desired.
