These notes are guidelines only please follow the instruction provided for specific competitions.
In most cases Image size should be 1600 x 1200 pixels in.jpg format at maximum quality Images will be projected onto a black background

In Adobe Photoshop or Elements (will vary with different versions)

1. Resize your image to 1600 x 1200 Pixels

a) FILE > OPEN click on your chosen file and click ‘Open’
Remember if you have done work in layers in Photoshop you should ‘flatten’ your image before resizing: LAYER > FLATTEN

b) IMAGE > MODE > RGB select 'Color' & '8 Bits'
(In Elements - if you are not prompted on opening, convert to 8 bits)

and tick the boxes - ‘Constrain Proportions’ and ‘Resample Image’
un-tick the box 'Scale Styles' and choose one of the ‘Bicubic’ options
(if you are not sure then just select ‘Bicubic’)
(Note: Older versions of Photoshop only have two boxes, tick both of these and carry on as above)

d) Still in the image size palette, you require to set the Pixel Dimensions:
If a ‘landscape’ (horizontal image) in ‘Pixel Dimensions’ > WIDTH >
type 1600x1200 (the height will be automatically filled in)
or If a ‘Portrait’ (vertical image) in ‘Pixel Dimensions’ > HEIGHT > type
1600 (the width will be automatically filled in) and left mouse click ‘OK’

2. How to set ‘sRGB’ as your colour space in Adobe Photoshop

With Adobe Photoshop open, and your image open go to


b) In ‘Destination Space’ for Profile select ‘sRGB IEC…’ which will be near the top and for ‘Conversion Options’ choose engine ‘Adobe (ACE)’ and Intent ‘Relative Colorimetric’ leave ‘Black Point..’ ticked and if the other two boxes are not greyed out ‘Use Dither’ and 'Flatten Image’ also tick them and left mouse click 'OK’

You can only do a basic conversion in Elements, you will not be able to do all of the above – you will find your settings in Edit ? Colour Settings, and if the file you are opening does not have a profile you will get a message coming up, (you can select sRGB here)

b) From the editor in Photoshop select File >? ‘Save as…’

Your Name_Competition Name_Image Title.jpg
Your filename must contain:
• Your Name and any photo awards eg John Le Page BPE2
• followed by _ then the Competition Name eg _Still Life
• Follwed by _ and then the Image Title eg _My Brilliant Vase
• It is best to use spaces in the title / name so they are easily read
Eg John Le Page BPE2_Still Life_My Brilliant Vase.jpg

Select ‘jpg' from the ‘format’ drop down list click > SAVE.
