At the meeting of Fraserburgh Photographic Society, held on April 26, members received a Digital Imaging Tutorial from Paul Woodburn.
This was the last tutorial of the season so Mr Woodburn spent the evening recapping the previous lessons and answering any queries that members had about Photoshop and showing different ways of achieving the same improvements to images.
He told members that all digital photographs needed some form of ‘sharpening.
This was because the pixels that make up the images are square and produce a slight blur where there are colour changes and boundaries. The usual way of doing this was using the ‘Unsharp Mask’, but Paul Woodburn demonstrated a sharpening technique using ‘High Pass Filter’, the ‘Overlay Blending Mode’, and ‘Opacity Slider’ which gave greater control over the finished result.
It was emphasised the sharpening of an image should be the last of the Photoshop operations to be undertaken
In response to questions Mr Woodburn showed members how to carry out the selection of complex object in an image such as a tree so that more detail could be shown by altering its exposure or how even that could then be used to enhance other images.
He also went through the complexities of image and canvas resizing.
Paul Woodburn suggested that this may become more important as judges may deduct points from wrongly sized images submitted into competition.
The next meeting is the Annual Dinner and Presentation night on May 10.
This is the last meeting of the season.
The 2012/13 season will start on September 6, 2012.
Details of the 2012/13 programme will be posted on the Fraserburgh Photographic Society’s website at www.fraserburghps.weebly.com as soon as it is available.
In the meantime the postings will continue on the website blog, available at the same address.
Last week, the Fraserburgh Photographic Society had reviewed images by Scottish Photographic Federation judge Matt Johnstone.
Matt Johnstone has won many awards for his photographs, many of which have been internationally exhibited.
