Introduction To Photoshop

This is my first time using Photoshop. My task was to compose an image using sand dunes, a bear, an astronaut and the Eiffel Tower.

Setting up a file and selecting images
I had to set up a file (International paper- A4) which was 800x1000 pixels and had a resolution of 72 pixels. I then named the file as 'Photoshop Test'. After that I used Google to use find for images which were: Sand Dunes, an astronaut, a bear and the Eiffel Tower. These images needed to be more than 400 pixels each. Then I saved these images into a file named 'Photoshop Images'.

Opening an image
I opened up my sand dune. To do this i went on File-open-Photoshop Images-sand dunes-open.

Scaling an image
I scaled my sand dunes. To do this went on Edit-transform-scale. Then I clicked on the corner of the photo and held down the shift key. This helps to keep the photo proportional.

Layers
I named the layer 'sand dune'. I did this so I knew what it was called for when it came to layering objects on top of the background.

Adding an image
I opened the image of The Eiffel Tower. To do this I use the same principle as when I opened up my sand dunes. Once open you drag the image on top of the sand dunes.

Zoom
I then used the zoom tool to enlarge the image of the Eiffel Tower. To enlarge the image you click on the image however to change the magnifying glass to zoom out  you hold down the shift key and then click on the image.

Polygonal Lasso Tool
I used the Polygonal Lasso Tool to cut out the background of the image. To do this you click on the side on the image and then join the dots up together. The lasso then has flashing dotted lines on the outside, to then delete the background you click inside the dots and press delete.

Image Adjustment
To make an adjustment to an image you click on Image-Adjustments. Then you can choose from the following Brightness/Contrast/Hue/Saturation/Levels.

Feathering
To give an image a softer edge after I used the Polygonal Lasso Tool. I used the feathering tool. I set it to 1 or 2 pixels this then makes the image less blunt around the edges.

Saving a file
To save the file I clicked on File- Save- Introduction To Photoshop. The when I finished my Introduction To Photoshop I save the file as a JPEG. To do this I clicked on File-Save As- Introduction To Photoshop- JPEG.
