Adobe Photoshop lesson 2

in this lesson i learned about image resolution and size and how to incorporate it to my advantage. I learned how to make a file from photoshop able to upload it to the internet on my Flickr account. I fully learned how to crop a image and size it to make good proportions to make it presentable. Then i learned how to retouch a image to make it either sharper or duller or even blur out certain parts of it. This was a complex lesson about how to make a image look better based on the photography and the amount of mega pixels you had which has a direct correlation to the sharpness of the image.
