Image Resizing

Image resizing

Please practice on a test image first.

These instructions help you to resize your image after you have edited and cropped your image to suit your needs. Resizing commonly has to be carried out to suit projected digital images (PDI’s) for competitions entry. To comply with Scottish Photographic Federation guidelines all Projected Digital Image entries must be not larger than 1600 pixels wide by 1200 pixels high.

The actual method will depend on the particular software which you use but, the following may help. In general, click on Image ( often from the Menu bar along the top ). When you click on Image a Drop Down menu will often appear. Click on Resize. Then choose Image Resize from the options which will appear. You will now see two sets of numbers, often labelled Pixel Dimensions and Document Size. You are interested in Pixel Dimensions. There will be a Width and a Height, each with a box to the right. If the box says Pixels, that is correct. If it says Percent, then click on the ‘down arrow’ beside each box and change both to Pixels. If your image is in a Landscape format, change the Width to 1600. The Height will change automatically to a value which ‘allows’ the Width of 1600 which you have entered. You may, therefore, see that your image is going to be resized to 1600 x 986. Don’t worry, that is ok. The 1600 x 1200 is a maximum size and you will probably have cropped your image, hence the altered Height figure. If your image is in a Portrait format, change the height to 1200, this time the Width will change automatically. You will also see a third box labelled Resolution, please change that to 300 with the line to the right stating Pixels/Inch. As before, clicking on the ‘down arrow’ will enable you to change to that if required. You may see a line on this panel which states Bicubic Smoother or Bicubic Sharper. The latter is usually preferred when you reduce the file size. Then click on OK. You now have a Resized image within your editing software. If you now choose File and Save As ( or perhaps Export ), you can save this edited and resized image in a folder of your Competition entries. The terminology may vary with different editing software programs but I hope this helps. Both Internal and External Competition Secretaries receive an enormous amount of images so please help them by resizing your entries. Please also remember to add “_JS ” to the filename if you wish one of your PDI’s each month to be entered to the Jim Stewart competition. Please don’t hesitate to get in touch with either a Competition Secretary, a Club Member or Committee Member if you are experiencing any difficulties or have any queries.
