Thank you, my girlfriend hated it because it's not natural looking, but art or creativity is seldom natural.
For other newbs as myself, we all have to cross this point at sometime and seldom ask for direction.
So, don't take this as an insult to your intelligence, but this is my basic method.
Hook your card reader to your pc (I don't know squat about apple).
Create a file on your pc with a unique name.
Open the flash drive holding the pics.
Drag and drop, or SAVE TO to move the pics to the folder.
Open each pic, then right click and RENAME. I make a name that fits.
Once open, you should see at the top the EDIT bar.
Do it.
You'll open up a different screen with basic tools available, try everything.
I like to increase the size to see small detail changes, and back out for overall looks.
Take your time and increase and decrease all the settings to see what they do,
Look carefully around for other options to try and max em out.
Crop, resize, light, dark shadows, go crazy, you don't have to keep anything.
Many will snear and laugh, as they are light years ahead, but some will try it.
Hope you do and post your results. We're here to help each other.
