I learnt how to use the lasso tool which allows you select more small detailed things such as eyes or a bottle without selecting the whole image. I have made steps on how to use this tool.
1. select the lasso icon form the left
2. select the standard lasso icon and use the free hand to draw an outline of the image you want
3. Photoshop will join the lines with a straight lines.
4.you then select the cropped image and are able to move it around.
5.you can delete the background an will be left with the image you used lasso on.
