[CMT] Working on Composite Face assignment in GIMP/Photoshop

Today I introduced some techniques used in working on the composite face assignment which is due on Wednesday. If you complete it early – choose a new set of faces and work on another one, then submit your best work.

Here are some tips:

  • use a transparent layer on the top of the stack – draw some marks on it for eyes, nose, mouth, outline of face, etc to use as a guide to align the facial features of the other layers
  • use the scale tool to make the faces bigger or smaller
  • use the rotate tool if necessary
  • use the move tool (choose “move active layer”) in order to align the facial features
  • remember that if one element appears on top of another in the stack of layers, it will cover up the ones underneath
  • use layer masks to show only the parts of the layers you want to be part of the picture
  • use a brush with fuzzy edges for smooth transitions between the different elements
  • to match skin tones you can use the levels to darken or lighten
  • to match skin tones you can create a colour layer of a darker skin-like colour, then blend with the one below using the “overlay” blend mode

[CMT] Introduction to the DSLR and Exposure

In class today we learned …

I provided some explainations and we watched a series of videos on exposure. Here are some links to similar explanations and examples:

We broke out the cameras and students had a chance to learn about some of the basic controls of a DSLR (Digital Single Lens Reflex) camera.

[CMT] Colorize, Desaturate, Layer Masks, Faking a Blurred Background

In class today we learned …

GIMP – We took a photo of a flower and and made several duplicate layers and then used the colorize tool to tint each one a different colour. We then applied layer masks to block out each layer and then selectively coloured in parts of the image different colours by painting white on the black layer masks.

We discussed the concept of depth of field in photography. We learned how to blur the background in GIMP in order to draw the viewer attention to the subject.
