Boreal with Branch

I am back in my studio but have to offer a R.I.P to my trusty Toshiba who finally died after limping along for oh so many years. I'm borrowing one of Trish's laptops but find that her tools are so up to date, I can hardly process my images. I long for the old Photoshop CS or plain old Elements. I opened the newest version of photoshop and was so entirely lost! Soon I'll bite the bullet and get a new laptop, but either way, I will need to update my image processing skills.
