Adding a Watermark to an Image

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.

Creating Spot Colour in a Monochrome Image

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.

Removing Objects From Images With Lightroom and/or Photoshop

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:

Reducing Image File Sizes with JPEG-Optimizer

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.

Using High Pass Filter Sharpening in Photoshop

There are many ways to sharpen images - all image editing software offers at least one. Many photographers use the tool within Lightroom, others rely on those offered by Photoshop. This software provides many ways of sharpening photos: Smart Sharpen, Unsharp Mask etc., but the High Pass filter is a great way to target sharpening a bit more precisely and it is a subtle, powerful and effective method.

 

David Kallmeier has written a brief illustrated guide to applying High Pass sharpening using Smart Objects in Photoshop which is available as a pdf file.

Long Lens Photography

Telephoto lenses are an essential tool for wildlife photography; few animals are considerate enough to allow us to come close enough with non-telephoto lenses. And there are some animals where it's prudent to maintain a healthy distance. This type of lens is also widely used for motorsport photography and they have their place in landscape photography too.

However, telephoto lenses have a number of properties, advantages and disadvantages that are worth understanding in order to maximise their use and help achieve the image you're after.

Recently Chris Bowers presented a well-attended Technical Meeting on the theory behind, and use of, telephoto lenses and a copy of his presentation is downloadable as a pdf.

Photography Glossary

When first starting photography the number of names and terms can be bewildering and daunting. Even those of us who have been doing this hobby for years don't know everything, or, more embarrassingly, may have been misusing a term due to a misunderstanding of what it actually means.

Luckily David Kallmeier has written a comprehensive glossary of photography terms, so if you don't know your IBIS from your ISO or think Red Eye is caused by excessive drinking the night before, download a copy of the pdf.

Macro Photography

Macro photography, sometimes referred to as close-up photography, is generally defined as capturing images of objects at close range so that they appear at life size (i.e. a ratio of 1:1) or greater.

This is often used to great affect by natural history programmes, especially those about insects and other invertebrates, to reveal a hidden world that's usually unseen. Macro photography should not be mistaken for photomicrography which utilises microscopes to image the truly, er, microscopic.

Macro photography doesn't need any specialist equipment - a telephoto lens can achieve suitable magnifications, but to really unlock this subject you will need additional hardware. This can range from cheap reversing rings to ring flashes and studio lighting rigs.

To help guide you through this fascinating subject David Kallmeier has kindly supplied the slides he used for his presentation, together with a useful and informative leaflet explaining the use of flash. Click on the links to download the pdfs.
