Re-Sizing Images for BSoUP digital competitions using Photoshop

by Alex Mustard

Lightroom users please download Keith Lyall's Notes

There are many brands of digital image manipulation software on the market, and within each program there are usually a number of ways of achieving a particular effect. Here I will describe how to use resize images in Photoshop using the 'IMAGE SIZE' tool within the IMAGE menu (this is a one step process and is available in all versions of Photoshop).

The resolution of the BSoUP digital projector is 1400 by 1050 pixels, and we must adjust our images to this size for optimal projection. This is actually a low resolution for a digital image (less than one Megapixel) so resizing for projection reduces the resolution of our original image.

The projected area from the digital projector (like a computer screen) is wider (1400 pixels) than it is high (1050 pixels).


This means that horizontal images will be projected larger than vertical images. You may wish to consider this when selecting your images.

1400 wide

Please note the current maximum size is 1400 pixels (493.80 mm) wide

1050 high

Please note the current maximum size is 1050 pixels (370.42 mm) high


1. Focus On Competitions

You should start with an image larger than 1400 by 1050 pixels (all digital camera and scanned images should easily exceed this size).

Open the image in Photoshop and crop if required. Then go to the IMAGE menu and open the IMAGE SIZE tool.

First ensure that the TWO options (Constrain Proportions and Resample Image) at the bottom of this box are checked. Then go to box labelled 'Resolution' (at the bottom of the 5 boxes) and change the value to 72 pixels/inch.

Resolution Pixels

Please note the current maximum is 72 pixels / inch

DO NOT click OK and immediately go to the 'Pixel Dimension' boxes (the top two boxes). If your image is a vertical you must change the value in the 'Height' box to 1050 pixels. If your image is horizontal you must change the value in the 'Width' box to 1400 pixels. (If you have cropped a horizontal image to a square format make sure that both the width and height values are equal to or less than 1400 and 1050 pixels, respectively.)

Save the image as a JPEG (.jpg) with an image title that includes your name (e.g. j_smith01.jpg).

2. Portfolio Competitions

Creating a digital portfolio is more complicated, and there are many ways to do it. Here I will suggest one approach. You do not necessarily need to follow these instructions to the letter as long as you end up with a portfolio of six images in two rows of three on a black background that measures 1400 by 1050 pixels and is at a resolution of 72 pixels/inch.

First select your six images and resize each to 450 pixels in their longest direction at 72 pixels/inch following the procedure detailed above.

450 x 450 pixels

Please note the current suggested maximum size per image is 450 pixels wide and 450 pixels high

We have already prepared a background with guidelines to help you layout your portfolio. These guidelines are only visible in Photoshop/Lightroom and will not be visible when you final portfolio is presented. Download the BSoUP_Grid.jpg, save it on your local hard disc and then open it  in Photoshop/Lightroom. In the VIEW menu select the option (Snap to> Guides), which means that Photoshop/Lightroom will ensure that each image is exactly over the crosses in the grid when you position them.

(Alternatively you can create a new file (FILE menu, option NEW) with a Width of 1400 pixels, a Height of 1050 pixels and 300 pixel/inch (you are asked for these when creating a new file). Fill the background of this new file with black (e.g. EDIT menu, option FILL, then fill Contents with black at an Opacity of 100%).)

Now copy and paste all your images onto the black background and arrange in two rows. As long as have Snap to Guides selected Photoshop will ensure that each image is positioned correctly.

1400 x 1050 pixels

Please note the current maximum size is 1400 pixels (493.80 mm) wide by 1050 pixels (370.42 mm) high

Each image is in a separate layer and can be moved independently. Once all the images are arranged correctly flatten the image (LAYER menu, Flatten Image) and save the image as a JPEG (.jpg) with an image title that includes your name (e.g. j_smith01.jpg).
