Kim Westerskov Workshop and the Dehaze filter.

Kim Westerskov Workshop and the Dehaze filter.

 

On Easter Saturday a group of us went on a field trip/workshop with Kim Westerskov.  Our task was to imagine we were taking photographs to illustrate a magazine article about Piha.  We were each to take somewhere between 20 and 100 images during the morning which we would analyse and discuss after lunch.

 

But, there were twelve of us, including Kim, so the uploading of images to Kim’s computer took longer than envisaged, and it was not possible to darken the available space in the campsite sufficiently for easy viewing with the projector.

 

We did get to view several images that Kim selected at random, and he discussed them in detail, and demonstrated how to process them using Adobe Camera Raw in Photoshop.  The most recurrent themes were:

 

  • Use the clone stamp and Content-aware Fill to de-clutter images and remove distracting elements
  • Straighten the horizon
  • Use the “dehaze” filter and the “clarity” slider to add punch where necessary.

 

We did not have time to see all the images that we took, and we would have liked to see the different ways in which each of us approached the task.  So, I created a small “pop-up” website for us to upload our images and comment on them.  Kim joined in this exercise with enthusiasm and his comments and images were very constructive.  He even went so far as to select some of our images and process them himself to demonstrate his ideas.

 

These comments are too valuable to be just thrown away, so they have been added as a resource for club members on our club website.  The link to view these “before and after” images is https://www.northshorephoto.co.nz/banda

 

Kim does not use Lightroom.  He organises his images in folders, and uses Bridge and Photoshop for processing.  It’s worth pointing out, therefore, that “Adobe Camera Raw” – ACR – is the engine that Photoshop uses to process raw images, and that this exact same engine is what drives the Lightroom “Develop” module.  The interface looks a little different, but the actual processing is exactly the same.

 

Kim also makes use of the “dehaze” filter.  This is a device to be found in the Adobe CC (subscription) software.  What is not common knowledge is that this same dehaze filter is available in the latest non-subscription versions of the software.  You have to jump through a few hoops, but the facility IS available in Lightroom 6 (non-CC version) and ACR 9.1 (non-CC version).  To access it in Lightroom, visit this website: https://cutthruthefog.wordpress.com/lightroom-6-dehaze/.   

 

To access it in ACR 9.1 or later, follow this link: https://www.dpreview.com/forums/post/56001178.  You don't need to make up all the files - I've done that and they are on our website here: https://www.northshorephoto.co.nz/sites/default/files/users/u1/Dehaze.zip.  Just find out where camera raw saves it's settings, and extract the contents of the zip file there.  To do dehazing, "load Settings" during raw conversion from the appropriate dehaze file.  It does the job, but without the convenient slider.
