Adding a watermark to your pictures may be desirable for a number of reasons. It can be your signature, so the person viewing the picture knows who took it; more proasically it can act as a deterrent to the theft of your image - stopping those who would copy it without crediting you.

This page contains links to tutorials produced by Club members, sometimes in response to a 'how do you do that?' question asked at a monthly meeting, but often to demonstrate techniques covered in one of the Technical Meetings.
We hope to gradually increase the number of tutorials in the months to come. If you would like a tutorial on a particular subject, check to see if it will be covered in one of our forthcoming Technical Meetings or, if not, let us know what you would like to see.
You may have seen black and white photos with one or more elements, usually the main subject, in colour and wondered how that effect was created.
This is called spot colour and starts with the entire photograph being in colour, then using photo editing software, such as Photoshop, to desaturate the colours.
When Kevan Brassington showed an image created this way at a Club meeting it created so much interest that he recorded the steps in a movie which you can see by clicking on the video on the right or by going to YouTube.
Ever taken a photograph which was spoiled by telephone wires? Or traffic cones? Frustrated that the only advice you get is to choose another viewpoint?
For our November 2018 Technical Meeting, Kevan demonstrated how to remove unwanted objects in images, using Lightroom and Photoshop, and he very kindly recorded four videos to show how he did it.
You can view the first of the videos by clicking on the picture on the right. To see them all in YouTube click on the following links:
With the ever-increasing megapixel sizes of image sensors in digital cameras, the file sizes they generate are increasing too. If you save your images in Raw format then these files can be over 40Mb in size and will increase further if edited in Photoshop. You may wish to reduce their sizes in order to email or archive them, or to upload to photo sharing sites.
There are many ways to reduce image file sizes that have little or no perceptible impact on the image quality - most image editing programs have these as options when saving files.
In the video opposite Kevan demonstrates using another method - JPEG-Optimizer - a web-based program that doesn't require installation on your computer.
