Image Correction and Editing – Photoshop

We have learnt how to use multiple image correction tools and methods to extend images, remove imperfections and re-colour.

These are some of the tools and notes I made during class.

Content aware scale (middle point makes sure nothing in that area is changed as drastically as other parts)  [middle point can be moved]
Content aware fill does a similar thing but with selections
Select the crop tool to get extra space on the side of your image, then use fill and content aware to add in extra information
Crop tool -> Marquee Tool -> Fill (content aware)
Content aware tool allows you to move a selection and leave a content aware fill behind it
Clone stamp tool= alt to sample and then click to use the tool (destructive and causes the image to look grainy)
Spot Healing Brush= samples surrounding pixels and then replaces the ones inside the brush (use sample all layers and use the spot healing brush on another layer to make this non0destructive)
Gaussian Blur -> Mask (Double click mask -> properties-> invert) -> use a brush with white paint set at a low opacity to blur out creases
cmd+Alt+Shift+E = merges all highlighted/selected layers
A combination of these tools/methods and previous ones were used to alter several images. (screenshots are shown to display layer structure)
We used  the crop tool to extend the canvas and then content aware fill to extend the actual image itself. Several similar adjustments were made throughout the image.
We used the spot healing brush to remove skin imperfections, Gaussian blur with a mask to blur/ease out wrinkles and creases and various adjustment layers to edit the values and turn the image black and white. The radial gradient tool with the colour to transparency setting was used with black to create vignetting around the edges of the image.





Here we had to use the tools and methods learn previously to remove the crinkles in the photograph as well as recolour parts of it. I used the spot healing brush for the crinkles and a layer set to colour for the recolouring.





Adjustment Layer Exercises – Photoshop

We learnt how to use Hue/Saturation and Levels adjustment layers. We also learnt how to use the Colour layer mode.

We used these layers to adjust the colours and value structure of the wine bottles image.

A combinations of masks and selections were used to isolate various parts of the images so that we were able to alter the colour and values of the car and wine bottle images. We also changed the background of the car image to black and white using a layer set to saturation and filled with black. The colour layer blending mode as well as various adjustment layers were used in regards to changing the colours and values of the two images.

A screenshot is included to show the layer structure, adjustment layers and masking experimentation.

The use of adjustment layers and layer settings is something that I have some experience in so this exercise was not too difficult although it was informative to see and experience different workflows and methods that make use of those layers/settings.

Destructive and Non-Destructive Editing – Photoshop

-Permanently destroying or altering pixels/images
-Cropping an image without saving a safe copy is destructive
-You are able to return to a previous unedited/unaltered state of the image whenever you want
-Creating a new layer and using the spot healing brush while sample all layers is on is an example of Non-Destructive editing.
-Using masks helps with Non-Destructive editing.
We used both Destructive and Non-Destructive editing to replace the sky in this cityscape/skyline. We used selections and masks to isolate the sky, we then proceeded to use the gradient tool to create a new sky.
When zoomed in, my selections and use of masks was slightly sloppy, so I need to work on using the tools for masks and selections more and perfect my editing of those masks and selections.

Photoshop Layer, Brushes and Eraser Exercises

We drew/painted an elephant and then either a cat or a dog while learning how to use the brush tool and eraser. The challenge was to use only a single layer.

Elephant (done using a mouse):


Since we were only using one layer and a mouse, I made use of various selections and low opacity soft brushes to paint the elephant. To get the silhouette I initially made large brush strokes and then erased away to get the right shape/s, the second time making the elephant I used the polygonal lasso tool.

Cat (done using a Wacom tablet):


For the cat drawing I used a Wacom tablet and a combination of the brush tool and the eraser.

Update: We have also learnt how to crop, edit destructively and edit non-destructively using the healing brush tool.
