- 5. Brainstorm – 1 minute - Timer
- 6. What is a digital image? • Millions of tiny, square- shaped block called? PIXELS • The blocks are arranged in a grid-like form called a bitmap • A pixel bitmap describes a digital image by the number of pixels along the horizontal and vertical axis.
- 7. Adobe Photoshop Filters - A filter can be applied to the overall images, individual layers or even smaller selections of the digital image. They work by applying a precise mathematical formula to every pixel in the bitmap, changing their colour or position. Creative, added interest…

- 2 minutes What is a digital image? Go through this slide and compare against their notes A digital image is made up of millions of tiny, square-shaped blocks called – does anyone know what they are called? Click Pixels. The blocks are arranged in a grid-like form called a bitmap. A pixel bitmap describes a digital image by the number of pixels along the horizontal and vertical axis. Many digital cameras and scanners are solder with a description of the maximum size image they can create such as 1200X1800. This figure refers to the actual number of pixels created in the bitmap. High-resolution images are made from millions of pixels and are able to describe curved shapes and fine details with clarity. Low-resolution images are made from far fewer pixels and cannot reproduce the same level of quality. The more pixels an image contains, the bigger and better a printout will be.
- Ask the participants if they can explain what a filter is? 1 minute All digital imaging software applications have a set of filters that can be applied to the overall image, individual layers or even smaller selections. So you can use any photo editing software Filters work by applying a precise mathematical formula to each and every pixel in the bitmap, changing their colour or position.
- Talk about the picture, - Watergate Bay in Cornwall, the dramatic scenery and the noise of the sea. We are going to use texture filters for this image.
- Bar with Essentials workspace drop down – application bar The bar with PS file is the menu bar Underneath is the options bar. Talk through the Tools panel and the Panels
- Open up the image in Photoshop – Click to go to next slide.
- Make sure you have unlocked your background, from the Filter>Filter Gallery>, select Watercolour - Hard to see the effect, so it might be better to zoom out, see all the different styles offered under watercolour, the style I wanted to apply is dry brush. Click to go to next slide.
- You can vary the brush detail, brush size and texture…. Click to go to next slide.
- A hand-crafted effect - Click to go to next slide.
- Now you can see the difference between the two. Click to go to next slide.
- This is a macro shot of a daffodil that I took at Trevano gardens in Cornwall. I chose Brush Strokes under Filter Gallery>Brush Strokes and then Accented Edges. See the default edge width, edge brightness and smoothness.
- Digital filters give the freedom to vary the visibility of special effects….now get them around the laptop ask them to choose a picture and get them to apply a filter….
