Monday 7/30/12: PS Intro

Welcome NYU Photoshop Intensive!



I'm very much looking forward to sharing my knowledge of Photoshop with you, and I can only hope you are just as excited to utilize and explore PS as a creative tool in the world of photography!

Before getting started, I wanted to point out that I like to begin each class with a quote that relates to that week's discussion material.  I think it's a fun way to introduce the lecture and I hope you enjoy them.  Below is our first quote, surprisingly enough not from a photographer but from Vincent Versace.  I think it sums up my philosophy about Photoshop, and shares with you how I'll approach teaching the course!  You'll also find I usually can't narrow it down to just one quote either...and they're often contradictory...so enjoy and decipher them as you see fit!
 
"Photoshop is not a verb. It is a noun. It is the means to an end, not the end itself." - Vincent Versace

"Photoshop – that which produces a great photograph from an average photographer." - Frank Karycinski


Bridge

Adobe Bridge is an organizational software that comes bundled with Photoshop and the Adobe Creative Suite package.  Think of it as a more robust file browser...like a basic mac window that's been spiced up!  Among other things, Bridge allows you to rename and organize files, assign colored labels or star ratings to images, edit the embedded metadata, and output to a pdf or web gallery.  Image files can also be shown in different sized thumbnails, slide shows or lists - making it more advantageous than a basic mac window for photographers and designers.

Photoshop

Adobe Photoshop is the industry leader in image-editing software.  It allows you to enhance, manipulate, and create imagery with endless possibilities!

Photoshop Tools


Pixel = Picture Element 
(Smallest square of color that makes up your image)

 


Resolution = total # of pixels in your image


Resolution can be defined by:
  • Dimension:  5184 x 3456
  • Overall Pixels: 17,915,904
  • Megapixel Value:  18MP

Output Resolutions
Optimal Output Resolution for PRINT = 300dpi
Optimal Output Resolution for MONITOR = 72ppi


File Formats
  • PSD (.psd = Photoshop Document):  Good for layers, but large file size and can only be opened in PS.
  • 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.

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


Great article explaining the differences in File Formats:
