We’ve used Adobe Photoshop to complete this process, which is available separately or as part of Adobe Creative Cloud. Some students are eligible for an extended free trial of Creative Cloud, and there are also ways to get Photoshop for free. You can find out how to achieve a cut-out like the model shown above in our ‘How to remove a background in Photoshop‘ tutorial. We’re working on just two layers in this image, but you might be working on lots more layers. Now, click the Lock button (it looks like a padlock) above the layers to lock that panel and all its properties. If you want to lock a group of layers you can select multiple layers and then click the Lock button. You’ll now see a little padlock symbol beside each locked layer. To unlock a layer, simply select it and click the Lock button again. The padlock symbol should disappear. To lock the transparent pixels in a layer, which will only allow you to edit the portions of a layer that are not transparent, click the square Lock Transparent Pixels button. If you have partially locked an image, the padlock symbol shown on that particular layer in the layers panel will not be completely filled in. Ashleigh is Tech Advisor’s Head of Affiliate.
