to convert a image for submition to the
Image Critique Gallery
a) Files should be submitted
as JPEG files (not TIFF, RAW, .psd or any other file type). Use quality
level 12 when saving the file.
First, using the IMAGE>Image Size box in Photoshop/Elements, adjust
the Image Resolution to 72 dpi (See below for method)
b) Next, adjust the longest side
dimensions of the image in pixels. These should be:
For LANDSCAPE ORIENTATED pictures 900 pixels along the LONG SIDE (width)
– the height will vary according to how the picture has been cropped.
For PORTRAIT orientated
picturesThe height must be a maximum of 768 pixels.
Again the width will vary according to the width/height ratio of the
If you are not sure how to do this, see below.
To ensure colour accuracy on the screen, make sure that your pictures
are saved in the sRGB colour space. If it has been produced using the
Adobe RGB (1998) colour space, change the space to sRGB (see below)
and adjust the colours on your screen to taste, before saving it.
(Changing from Adobe RGB (1998) to sRGB can sometimes result in the
pictures looking more saturated. You can combat this by lowering the
saturation a little in the Hue/Saturation Box). This effect will be
more obvious on some pictures more than others.
