I disagree, there are only a few things you need to know in photoshop or any other image editing programme to make a picture presentable at the level we need. If you want to be a professional that's different kettle of fish but its like driving. You don't need to know the same to drive a car on the road as you do to be an F1 driver and the basics will get you from A to B. When editing the photo to our standard all you need is to crop, change the levels and maybe but rarely do any touching up.
That is unless you're putting your photos in Vogue of course.
My son was doing a course his photography and I was able to get the RSPB photographer for a day to teach him some techniques and tips. I also attended and he showed us what is needed to turn snap into a photograph and its not really a lot despite a lot of professionals wanting you believe otherwise.
