Masks and Channels

For this week, I learned how to refine selections in quick mask mode and save a selection as a channel mask.
Of couse, I used a picture(above) that I downloaded from the web. This is how I did it:

First, I dragged the picture that I've downloadeed from the web into photoshop.

Secondly, I made a selection using the Lasso tool. Using it, I drag the tool outside and around the tiger's body, not on its edge but a bit further from its edges.

Thirdly, I switched to Quick Mask Mode. By doing this the image is overlaid with semi transparent red except for the selected areas which I have made with the Lasso tool.

Next, I refined my selection by using the brush tool.

Then, I load my selection by chosing Layer>Load selection. I chose quick mask for channel and ticked the 'invert' and selected 'ok'. By then, quick mask layer will appear under the CHANNELS section. I also saved my selection by Layer>Save selection.

After that, I head to Layer>New Adjustmen Layer>Levels...and clicked OK in the new layer dialog box. This is to enable me to adjust the gamma levels for my image. What I did was I adjusted the levels gamma slider to darken up a bit the surroundings of the tiger.

 There you have it, it's done!
