Week one what I learned

Today in class I learned how to make a lens flair, and also how to go through the different modes for layers. To go through the different mode you use SHIFT COMMAND + then you are able to see the effect of the different modes. I also learned how to merge only the layers that are visible into one layer so that you can have one layer with everything on it, to do that you press OPTION and then click on the little triangle on the layers panel and you can merge the layers.
