sRGB and RESIZING IMAGES FOR DIGITAL COMPETITIONS

sRGB

As it is a requirement that any image entered into WCPF competitions be in the sRGB Colour Profile, Stroud Camera Club has set this as our colour standard. We have also calibrated our projector equipment to sRGB.
If your image is not calibrated to sRGB it may not look the same as you expected when using our projector. For this reason it is recommended that all images are converted to sRGB for competitions. Please see the video below on how to do so in both Photoshop and Lightroom.

RESIZING IMAGES FOR DIGITAL COMPETITIONS

For our Club Competitions, we use a projector which has a resolution of 1400 by 1050 pixels. This is why we ask for digital images to be no wider than 1400 pixels and no taller than 1050 pixels.

When resizing for projection, you need to consider the image format:-

– for landscape format, change the Width to 1400;

– for portrait format, change the Height to 1050.

Be careful with square-crop or unusually-cropped images. Always check that the resulting Width AND Height are both within the limits. If changing one dimension leaves the other too large, simply go back and change the other dimension instead.

Always be sure to maximize one of the dimensions of your image fills the screen as much as possible and resize with the aspect ratio preserved to avoid distortion. After resizing, the image will usually look softer, so it is often necessary to apply a little sharpening.

Please also remember not to overwrite your original file – save this resized image under a new name.

For submission to the club competitions the file name needs  to be in the following format:
Name of Photographer_Image title with no additional wording except the .jpg extension for example: Joe Bloggs_Lovely Sunset.jpg

Below is some guidance using diferent software products

  • Open the image and choose “Image->Image Size” from the drop down menu
  • In the  pop-up window that has now appeared, make sure “Constrain Proportions” and “Resample Image” are both ticked and that “Bicubic Sharpener” is selected.
  • Under the “Pixel Dimensions” section at the top, you can now edit the values for Width or Height as required. Don’t worry about any of the numbers in the “Document Size” section.
  • Either change Width to 1400 or Height to 1050, as appropriate, and the other value will be automatically scaled in proportion.
  • Now click the “OK” button, sharpen if needed, and save the resized version with a new name.
  • Open the image and choose “Image->Resize->Image Size” from the menu which opens a pop-up window.
  • At the bottom, make sure “Constrain Proportions” and “Resample Image” are both ticked, also make sure that “Bicubic” is selectected
  • Under the “Pixel Dimensions” section at the top, you can now edit the values for Width or Height as required. Don’t worry about any of the numbers in the “Document Size” section – this is important when printing images but has no impact on Digital Images for projection or viewing on a screen.
  • Either change Width to 1400 or Height to 1050, as appropriate, and the other value will be automatically scaled in proportion.
  • Now click the “OK” button, sharpen if needed, and save the resized version with a new name.
  • Select your photo with a left-click, then choose “File->Export Picture to Folder” from the menu which brings up a pop-up window.
  • Note the “Export Location” which usually defaults to something like your “My PicturesPicasaExports” folder. Below is the suggested sub-folder to place your resized images in.
    Make sure “Resize to:” is selected.
  • Note that Picasa will adjust the larger dimension to the value you ask for rather than the width or height specifically.
  • For landscape format pictures, simply set the slider to 1400. If your picture is in portrait format, click in the box and type in 1050.
  • Ensure the “Add Watermark” box is not selected when producing competition entry images.
  • Press the “Export” button which should then produce a resized copy of your image and open a Windows Explorer at its location.
  • Open the image and choose “Image->Resize” from the menu which opens a pop-up window.
  • Ignore values in the “Print Size” section, and below in the “Pixel Dimensions” section, choose “Pixels” from the drop-down menu on the right as opposed to “Percent”.
  • You should now be able to click on and change the “New” values for either Width or Height with the other value automatically scaled so long as “Lock Aspect Ratio” is selected in the Advanced Options.
  • Now click the “OK” button, sharpen if needed, and save the resized version with a new name.
  • Click Image on the Menu toolbar and scroll down the drop-down menu to Resize/Resample.
  • On the left-hand side of the box the current image size is shown at the top. Just below this check the Set new size and Pixels buttons. Further down, tick the Preserve aspect ratio box and set DPI to 300.
  • For a portrait image, type 1050 in the Height box. The Width box should show a figure less than 1400 (if not, it isn’t a portrait image!).
  • For a landscape image, start by typing 1400 in the Width box and check the figure in the Height box. If it’s 1050 or less, that’s it; if not, treat it as a portrait image, ie type 1050 in the Height box.
  • On the right-hand side of the box, click the Resample (better quality) button. This should also result in a sharper image. (If not, it would be best to undo the resizing, sharpen the original image a little, then resize.)
  • Click OK and your image will now have been re-sized to the pixel dimensions and resolution required for projection.
  • You now have to save it as a jpeg.
  • Click File on the Menu toolbar and scroll down to Save as.
  • In the JPEG/GIF save options box move the Save quality slider to the furthest right position. (Don’t worry about any of the other boxes.)
  • If you have followed the earlier advice you will have been working in some other format, but if not, remember to use a different file name so that you don’t overwrite your original.
