How to Resize your Digital images for competitions

NSLPS Digital competitions have a size limit of 768 x 768 pixels, and a maximum of 220KB. The following steps will help you resize your image to meet these requirements.

For Photoshop (PS6, PS7, CS & CS2)

STEP 1 - Make a Copy

The following operations modify the image and therefore should only be carried out on a copy.

STEP 2 - Convert to sRGB Colour Profile

 

Photoshop CS2 - Go to Edit menu and select Convert to Profile. If the source space is not sRGB then select sRGB IEC61966-2.1 for the Destination Space Profile. For RAW images a preferred alternative is to use Camera Raw and set Space to sRGB IEC61966-1.

Photoshop CS and earlier - Go to Image menu and select Mode then choose Convert to Profile. If the source space is not sRGB then select sRGB IEC61966-2.1 for the Destination Space profile.

STEP 3 - Set Image Mode

Go to Image menu, select Mode and change to 8 Bits/Channel.

STEP 4 - Resize

Go to File menu, select Automate, select Fit Image.

In the Constrain within: enter width - 768, height - 768.

STEP 5 - Sharpen

Take the opportunity to sharpen the image at this stage if required

STEP 6 - Save for Web

Go to the File menu and select Save for Web. Select JPEG and set the quality to maximum. Check the ICC Profile box to embed the sRGB profile.

Select Image Size, check Constrain Proportions and under Quality select Bicubic Sharper (Photoshop CS and later) or Bicubic (Photoshop 7 and earlier).

For a landscape image set the Width to 768 pixels. Check that the Height is 768 pixels or less. For a portrait image set the Height to 768 pixels. Check that the Width is 768 pixels or less.

If the filesize is more than 220K, then click the (>) Optimise menu - next to Settings, and select Optimise to Filesize. Enter filesize - 220, then click OK.

If it is still larger than 220K, or you are unhappy with the quality, try reducing the pixels eg. to a width/height of 700

Click Save. In the file dialogue box make the file name the same as the author's name with the title following i.e.,

john_wheeler_the_shearers.jpg.

(Do not use spaces in your filename. Use the underscore character instead both for words in the title and to join the author's name. Do not use upper case characters).
