Tuesday 7/31/12: Layers + Selections

"As an artist, I work to gain technical skill in order to become more fluid, more expressive and more creative in my craft. Technique is always at the service of creativity." - Evan Chong

"A toast to film? You bet. But don't forget the Photoshop chaser." - Herbert Keppler; Film vs. Photoshop. (Popular Photography & Imaging, March 2006)

File Formats
  • JPEG (.jpg = Joint Photographic Expert Group): Compresses photos into a smaller file size, but degrades photo quality.  Good for email or web and is recognized by almost all software programs.
  • TIFF (.tif = Tagged Image File Format): Larger file size, but good image quality.  Best for printing.  Tiff file can be saved with or without layers and is recognized by many software programs.
  • RAW (.raw/.cr2/.nef/... = Raw) = Most flexible file format for photographers since no data has been processed.  But you must process a file into a workable file format before using...which requires more skill and knowledge.
  • PSD (.psd = Photoshop Document):  Good for layers, but large file size and can only be opened in PS.

Saving Image Files Recap:
  •  For Print = Tiff @ 300dpi
  • For Web or Email = Jpeg @ 72dpi
  • With Layers = PSD @ optimal resolution (usually 300dpi)

Layers

Layers are the backbone of Photoshop.  New elements can be placed on individual layers and each layer can be edited and manipulated without effecting any other layer.  An original image starts off with only a single layer titled background.  You can then add these additional layers:

  • New Blank Layer
  • Text Layer
  • Another Image Layer
  • Adjustment Layer
