HOW TO COMMUNICATE WITH A STOCK PHOTOGRAPHY SELLER: 
(or at least know what the heck they are saying ...)

The stock photography world has gone digital. Most stock houses now specify
file sizes and cameras that are acceptable in terms of their image quality.

These cameras are: Canon EOS, Nikon Pro, and Medium Format Camera backs.

DIGITAL STILL PHOTOGRAPHY FORMATS: 

DIGITAL:
We shoot with high-end Digital SLR cameras such as the Full Frame Canon EOS Digital Camera
This camera creates image files large enough for a two-page spread in print.


DIGITAL SERVICES:
Digital Post-Production: 
Image processing done after the film is processed.
For a quality project like this, plan on taking advantage of digital
post-production to color-correct and optimize the scans, remove unwanted items, fine tune the exposure, contrast, etc. for output. Every scan will need at least a bit of digital time to optimize.

Digital Files:
TIFF: best for all-around use, including publications. When in doubt, get a .tiff
PSD: Photoshop (TM) format, you need an image-processing software to open it.
PCD: Kodak Photo-CD (TM) Format
JPEG: a compressed file, use these for posting on the web and Powerpoint (TM).
PDF: Adobe Acrobat (TM) file that works great for documents.

FACT: Opening and re-saving a JPEG degrades quality as the image is recompressed. PDF files are used widely in color pre-press.

We also offer:

Digital retouching, color correction, and enhancement
File prep for offset printing, websites, trade shows, etc.
File conversion to fit your needs to a 'pixel.'

Complete corporate identity
Logo Design
Publication design: color brochures
Design Competition entries
Trade show graphics, giant prints, and collateral.
