Resizing Images for Projected Image Competitions

How to Resize and Save Images for Projected Image Competitions

Here are some techniques for resizing your photos for projected image competitions under the VAPS / Corio Bay Camera Club Rules.

A Printable version of these instructions can be downloaded here.

1. Photoshop

1. Go to Image -> Image size. The Image size option box will appear.

2. Ensure the “Resample Image” and “Constrain Proportions” check boxes are ticked

3. Remember that your images must not be more than 1920 pixels wide or 1080 pixels high. If your image is in “Landscape” mode, set the width in the “Pixel Dimensions” box to 1920. If it is in “Portrait” mode, set the height to 1080. This will change the height or width (depending on which mode you are working in) to maintain the aspect ratio.

4. If you are working in “Landscape” mode and the new image height is less than 1080 pixels you don’t need to do anything else. If it is more than 1080, change the height to 1080 and let Photoshop set the width. (If you are working in “Portrait” mode the width will always be well below the maximum width)

5. Click O.K.

6. Go to File -> Save As

Important: don’t just go to “Save” because you will overwrite your original high resolution image and you won’t be able to get it back

7. Name your file according to the file format for club competitions.

8. In the Format box make sure the format is JPEG. If not, select JPEG from the drop down list.

9. Chose the Folder you want to save the file into (I use a special “Competition Entries” folder) and click Save.

10. In the In the JPEG Quality Options box which appears, move the slider until the number on the right is below 5Mb.

4. Under Files Settings, select JPEG, and sRGB. Also make sure the “Limit File Size To” box is checked and enter 5000 in the text box.
