Photoshop Lesson 4


Photoshop layers are like clear sheets. You can see through transparent areas of a layer to the layers below. You move a layer to position the content on the layer. You can also change the opacity of a layer to make content partially transparent.  Individual layers can be edited , repositioned and deleted without affecting the other sheets.

You use layers to perform tasks such as compositing multiple images, adding text to an image, or adding vector graphic shapes. You can apply a layer style to add a special effect such as a drop shadow or a glow.

A new image has a single layer. The number of additional layers, layer effects, and layer sets you can add to an image is limited only by your computer’s memory.

You work with layers in the Layers panel. Layer groups help you organize and manage layers. You can use groups to arrange your layers in a logical order and to reduce clutter in the Layers panel. You can nest groups within other groups. You can also use groups to apply attributes and masks to multiple layers simultaneously.


In lesson 4 we start with a single image of a pineapple:


 The end product is a postcard with text:
The  start image has 5 layers. Another is added by dragging the image of a beach onto the photo. The final image is created by editing individual layers
Double click to rename layers.
Click the eye icon to view or hide individual layers.
The order of layers on an image can be changed by selecting and moving them up or down in the Layers panel.
Individual layers can be altered without affecting the whole image. For example adding a border, changing opacity, resizing and rotating.
In Lesson 4 I have learnt to:
  • Organise artwork on layers.
  • Create, view, hide and select layers.
  • Rearrange layers to change the stacking order of artwork.
  • Apply blending modes to layers. Right click the chosen layer to duplicate. Select copied layer and choose Overlay from the Blending modes in the Layers panel. Blend the copy with original to create more vibrant image.
  • Resize and rotate layers. Chose the layer you want to work on. Edit>Free Transform. Tick the commit transform to finish.
  • Apply a gradient to a layer. Select layer>right click>select pixels.Gradient tool in Tools panel. Change foreground colour. Drag the Gradient tool from top to bottom to apply gradient.
  • Apply a filter to a later. Select layer. New Layer button, name the layer can then adjust the foreground and background colours and apply by Filter>Render>select layer
  • Add text and layer effects to a layer. Can add text or edit existing text using Horizontal Type tool  and Character panel
  • Add an adjustment layer. Can apply colour adjustments without changing the pixels e.g. hue/saturation in the Adjustments panel.
  • Add a border. Select>All   Select>Modify>Border  select number of pixels, foreground colour. Edit>Fill  OK  Deselect all.
  • Save a copy of the file with the layers flattened merge layers to reduce file size. Can no longer edit flattened image so good idea to duplicate. Image>Duplicate. Rename  then go to  Layers panel>flatten image. Save
