Larry in Georgia asks:
Why are there no formal classes on Photoshop to be found? This question came to mind because so many of the photos on your site are comprised of what to me appears as being rather complicated Photoshop techniques employing multiple steps. Yet, in my area of the country, formal classes are nowhere to be found.
As a verification of the above points, in 2015 Linkedin paid $1.5B for lynda.com which is THE best online learning site. On lynda.com you spend $25 for a month of access and learn Photoshop (plus any other computer software) from the very best presenters. It's less than a local face-to-face class (if there was one) and the training is better than most local teachers are likely to give.
I should also point out that there is also a lot of good free video tutorials on YouTube but finding the good ones can take some work. I have a page where I compile a list of free video tutorials on the subject of real estate photography and post-processing (the white ad that says "Free Real Estate Photography Tutorials" on the lower right sidebar). Let me know if you have some favorite free videos that should be on this list.
