Guide to preparing images files for projection and competition (examples prepared using PhotoShop CS3 and based on my own methods) Images files should be saved in the following format - sRGB colour space Max width 1024p, Max height 768p TIP! Avoid frustration and anger. Save your file to a new name and location before any conversion or resizing. Here's what to do Converting to a new profile If you shoot in jpeg and have your camera colour space set to sRGB then you can omit this stage. Otherwise > If an image has any other profile, for example adobe RGB, you will need to convert in PhotoShop > Open image in Photoshop From the ‘Edit’ menu choose ‘Convert to Profile’
A dialogue box will open > 'Source Space' is the current embedded profile of your image file. 'Destination Space' is the profile you wish to convert to. In the drop down menu locate and click on sRGB IE61966-2.1 (There's a long list of profiles but all the common ones are grouped together near the top)
Conversion options are safely left as default.t Click OK but do not save the file yet. Resizing the image Images should be no wider than 1024pixels and no higher than 768pixels From the 'Image' menu, choose > Image Size
In the lower part of the dialogue box,
check the three boxes, 'Scale Styles' 'Constrain Proportions' and 'Resample Image' then from the drop down menu, choose 'Bicubic Sharper' Now, type in the pixel dimensions. In the example, the image is portrait format, so we need to think about the height. It should be no more than 768 high - so type in only the Height 768 [pixels]. For an image that is landscape format, type in only the Width 1024 and check that the number in the height box is no larger than 768.. Click OK Now, Saving an image to the required file size DPS internal competitions require a jpeg file saved to 'Medium' compression From the 'File' menu, choose -'Save As'
Type in your filename > From the Format menu choose, JPEG > then click Save
In 'Image Options' enter a number from 5 to 7. 'Medium' will appear in the box to the right. (Higher numbers apply lower levels of compression and result in larger file sizes. ie., more Kilobytes) All other options can be safely left at default setting. Now click OK. Your file should now be ready to send to your competition secretary. NOTE Requirements for some external competitions, eg., PAGB, vary from those of Durham Photographic Society but the methods of adjustment remain the same. Hope this helps. JB |
