PREPARING AN IMAGE FOR DIGITAL PROJECTION

 

These steps assume you have already edited and prepared your image to look as good as possible including cropping and sharpening. They pertain to Adobe Photoshop and Adobe Photoshop Elements but other editors may also achieve the same things but are outside of this advice.

 

  1. Set the image colour space to sRGB for projection or computer usage (RGB for printing)

 

  1. Choose for Photoshop Edit > Convert to Profile and select sRGB.  For Elements Edit > Color Settings > Always Optimise Color Settings for Computer Screens

  2. Confirm when the image is sRGB profile, if not then convert it (Not assign) to sRGB.  Confirm the that the image still looks as good as before.  If not some more editing ….

     

  1. Re-sampling / Resizing for a digital projected image (DPI)

 

  1. Choose Image > Image Size (Photoshop) or Image > Resize > Image Size (Elements)

  2. Select Scale Styles, Constrain Proportions and Re-sample image with Bi-cubic automatic (Photoshop) or Bicubic Sharper as the interpolation method.

  3. To maintain the current aspect ratio, keep Constrain Proportions selected. This option automatically updates the width as you change the height, and vice versa.

  4. In Pixel Dimensions, enter values for Width and / or Height. Remember for projected images in club competitions, the maximum width is 1600 pixels and the maximum height is 1200 pixels (4 x 3 ratio)

  5. Important - if either dimension exceeds the maximum then adjust until one dimension meets the maximum and the other is less than or exactly equal to the maximum, then click OK.

  6. Finally apply additional sharpening if needed (see 3/4) and then apply a stroke (border) if desired (recommend 2-4 pixels width and colour white) see below.

     

  1. Adding a Border

 

  1. To place border around the image double click layer, select stroke, change position to inside, pixels to 2, 3 or 4. Change border colour as required.  Note that in the club when images are projected, they are projected on a black background, therefore a white or other light colour border will separate your image from the background and contain the image when viewed.

  2. For Elements version 9 and above, select edit > stroke then as per above.

     

  1. Naming your Image

 

  1. The name of your file will be the projected name, so it should be titled and spelled correctly.

  2. The format is as follows: - <entry number><single space> <entry title><.jpg> . Precede the image number with a zero.  So for an image called 'Rose Garden' the image should be named 01 Rose Garden.jpg                    

  3. Up to three entries are permissable but on very large entries the third entry may be dropped.  Please be aware of this.

  4. A good title can both enhance your image and add to the viewers understanding and enjoyment of it.
