Refining the edges of a cut away in Photoshop can be a tricky proceedure, but with time and effort, and definitely patience, the results can be very worthwhile.  Especially so if you have work from clients, for example, who are relying on a job being completed to a  highly professional level.

In class I used a model for my example, either downloaded from usb stick or from the internet.  I then used the selection tools (mainly ‘polygonal lasso’ and the ‘quick selection’) to draw a rough outline of my model.  After this, I pasted my model onto a selected background (Fig 1 – Original Picture) (Fig 2 – Model on new background) and then undertook the more pain-staking process of finely selecting the edges of the models hair (which, as you will see, was not the easiest of tasks), cutting in slightly as not to retain any unwanted, original background, again using the ‘polygonal lasso’ selection tool.

When this was complete I made sure any selection tool was selected, then opened the ‘Refine Edge’ tool box.  Here I am presented with a variety of options to help me fine tune my image to gain the desired effect and help give the impression that the model fits comfortable with the background.

I used feathering and softening to smooth out the edges of the ends of the models hair and the brush tool to create a more seamless blend of model and environment.  The radius tool assisted in this and the decontaminate colours option helped to clear up the less noticeable influences of background colour that had leaked onto the model.

I had another go later with a different model with the following results:

As I review these blogs and update when I feel necessary, continuing examples may appear below.  Hopefully showing improvement.

Today we looked at Persistence of Vision (POV) and Convergence.  POV is the generally encouraged theory that the eye retains some information from what we have just previously seen and merges it together, seamlessly with what we are currently seeing, hence how we perceive moving images or movies.  Below are two examples of POV:

This is a series of images Eadweard Muybridge (who proved the theory that horses completely leave the ground whilst running) used.  I used the rectangular selection tool in Photoshop to copy each image on to seperate layers, then set the transition time and saved the following series as a GIFF file using the ‘Animation’ tool in order to view the progession of the images on the internet:

Here is another example using the same technique but a bit larger and clearer.  I will also note that when saving the image as a GIFF file I reduced the RGB (or in this case, monochrome) in order to reduce the file size, but not necessarily noticeably reducing the quality (Image by Gordon McConnell, taken from http://www.brogallery.com/artists-links/gordon-mcconnell/ :

And the POV:

Convergence

Convergence is the coming together of technologies.  For example, in the case of DSLR’s, convergence is the ability to shoot film on a predominantly still frame camera.  Below is an example of a movie created on a still frame camera (Canon EOS 5d Mark II), a beautiful example of convergence, especially with the narrow depth of field achieved via the full frame sensor:

Below is another example of a Persistence of Vision that I saved as a GIFF file.  Something put together for a bit of fun and creative outlet:

I used images from the web to construct individual layers on photoshop and carefully put them into a sequence where the unassuming cow is abducted by quick ‘pass-and-grab’ alien kidnappers.
