Tech specifications for projected image

To insure that your digital images conform to standard, please follow these directions:

A. Set your working space to the Adobe RGB (1998) standard. In Photoshop (and most imaging programs), go to the Menu: Edit -> Colour Setting.

B. Size your images to the pixel sizes below:

1) The maximum image size that can be projected is 1024 X 768 pixels (native XGA). You can make the image smaller if you wish.

2) From your scanned slide or negative or digital camera image, set your image size. If using Photoshop, go to the Menu: Image -> Image Size.

3) Check the constrain proportions and resample boxes.

4) For a horizontal image, set pixels dimensions width only to 1024. The height will adjust automatically.

5) For a vertical or square image, set pixels dimensions height only to 768. The width will adjust automatically.

6) Click OK. Do not be concerned about document size, resolution, or file size. Do not change the resolution to 72.

7) Now you can manipulate and sharpen your image suitable for digital projection. Do not over-sharpen. Do not save as jpg files during editing as image quality will be lost. For editing save as a tif file. Save as a jpg file once and only after all changes have been made. Be sure your monitor is calibrated. We will not make colour corrections or other adjustments to the submitted digital files.

8) Rename each file in lower case to include; a two digit number from 01 and 02; author's first name as an initial and last name in full; and image name. (e.g. 01dbromleypinkflower.jpg). Save final edited version as a jpg High Quality (setting 12) file.

9) In the body of the email type in CAPITALS – IMAGE #, IMAGE TITLE, YOUR NAME, YOUR LEVEL #. (e.g. 01 PINK FLOWER DAVID BROMLEY L5)

10) Do not put any copyright information or any text on the image.

11) Email images to Dave Bromley at drbrom20@yahoo.ca by the Thursday night before the Monday Projected Image meeting.

12) If you do not follow the instructions exactly or you are late, your images may not get entered.

13) If you have any questions or problems email David Bromley at drbrom20@yahoo.ca

To better understand photographs as digital files - standard procedures, calibration of devices, resolution of an image, various file formats, issues relevant to correct colour reproduction -
please download and read Universal Photographic Digital Imaging Guidelines in PDF format - the link is on the right side of the following page, it is the third link. Highly recommended, and the information is free!

As they state on their page: "The UPDIG guidelines aim to clarify issues affecting accurate reproduction and management of digital image files. Although they largely reflect a photographer’s perspective, anyone working with digital images should find them useful."

The guidelines were prepared by the UPDIG Working Group.
