SIZING IMAGES FOR DIGITAL SLIDE PROJECTION

Use the ‘save’ or ‘save as’ feature to save and archive your image for

longterm storage. Now convert your image for slide projection.

1. Check the documentation on your image that it is an 8 bit RGB file.

2. Check that your image color-space is in fact sRGB. If it is not, in

Photoshop go: Edit > Convert to Profile > Destination Space

Profile: Working RGB - sRGB IEC61966 - 2.1.

3. You are now ready to downsize your image. Go: Image > Image Size >

in the boxes at the bottom, put a check in: Constrain Proportions and

Resample Image. In the drop down list, select ‘Bicubic Sharpen.’ (This

should allow the image to maintain its sharpness that you applied when

doing your work-flow). Disregard the data in the middle under Document

Size. This is only a concern if you are making a print of your image. Under

Pixel Dimensions: for horizontal format images, enter 1024 pixels in the

Width box. Check that the height does not exceed 768 pixels. If it does,

enter 768 on the Height box. (If this is the case, the Width will now be

something less then 1024). If your image is a vertical format, under Pixel

Dimensions, enter 768 in the Height box.

4. Ensure the file name of the image is kept short, uncluttered of your filing

information and is identical to the title submitted for the image. If the

image is not named, then the file name and title should be listed as

‘unnamed_01’ for example..

4a  DO NOT USE ANY PUNCTUATION in your file names.   The only characters allowed by

the Windows system are the Alpha characters A-Z, The numbers 0-9 and the - and _

(Dash and Shifted Dash)

Periods, question marks etc will make the image impossible to display on the PC.   On

the Mac, some of these extra characters are allowed but they will not work on the PC.

Some characters prevent the PC from renaming the files and will result in the files having

to be dropped from a competition as they will be impossible to change at the meetings.

Thanks for your cooperation.

5. Save your image, go > File > Save As > in the Format drop down list

select > JPEG and click OK. The JPEG Options will now appear. Move the

Quality Slider to 12 Maximum. Click OK.
