Photoshop and Lightroom can be very intimidating. I suggest you skip Photoshop for the time being. I only use Lightroom (LR) for 95% of my images. I started using LR 3 years ago. what really helped me was finding a "workflow" that I could methodically follow every time. My workflow is based on reviewing several tutorials. It is a series of steps and only takes a couple minutes per image. A few images then take additional steps.

My "Develop" workflow is as follows:
1. Crop
2. Set black point
3. Set White point
4. Open shadows
5. Reduce highlights
6. Increase texture
7. Increase clarity
8. Increase luminance

I observe the changes in each step and back off if I don't like the look of each adjustment. Much of the time that's where I can stop. With some images I may need to increase exposure or contrast. Then I may decide to add sharpening and/or noise reduction. Remember changes made in LR are non destructive so you can always revert to your original.

Take it slow until you feel comfortable with your workflow. You can then learn how to use more localized adjustment tools and add them to the workflow. There are loads of other adjustments available in LR but it takes time and experience to learn them.

The best way I have found to learn the software is to take it a little at a time. There are things that are most common that photographers need to know. Learn those first. Then if you want get books on the subject and go through them a little each day.

I don’t recommend live classes because they go too fast and don’t repeat so it never enters long term memory. I recommend Udemy.com or Lynda.com for classes that you can repeat and rewind as needed.

The most important thing I can say is don’t sweat not knowing everything about PP. Very few do. Just learn the basics. Don’t give up. Take it a day at a time and learn the next thing each day.

I used my first "personal computer" software about 40 years ago. I had two programs...a text editor called WordStar and a spreadsheet program called MultiPlan. Each offered huge productivity advances over the pencil and paper work we had been doing. They each added revolutionary value to our ability to do productive work, even though they were both very primitive when compared to what is available today.

It wasn't too long before Lotus 1-2-3 came along. Everyone was clamoring to get it. It let you have three worksheets in each file. Pretty soon, it would even let you make simple graphs. Over the years, the floodgates opened. Programs that did fancier graphs, provided color choices, and even choices of fonts. Lots fancier looking...very impressive, in fact, but very little that truly enhanced meaningful analytical capabilities for most people...lots of "form," but not a whole lot of meaningful "substance" for the vast majority of people. In fact, the software became an end in itself, consuming untold numbers of work hours with very little added intelligence.

In my mind, there is a real parallel with photo processing software for the majority of us. Early photo editors, including Paint Shop (which I've never used) and Microsoft Photo Manager (which I have used) offered the revolutionary ability to make some quick, easy, and incredibly useful adjustments to photographs. It was revolutionary, in fact. But the same thing happened all over again. Features were added, computers got more powerful, so more features were added, and pretty soon we ended up with these monster programs full of capabilities that no one really ever asked for.

Of course, there have also been some other parallel paths. In the 1970s, calculator nerds salivated over which calculator could compute 69 factorial fastest (the largest calculated number that scientific calculators could display). Or which calculators carried 13 digits of precision and which carried only 10.

Later, there were other folks who spent hours stretching the capabilities of spreadsheets to do calculations and analyses that no one else cared about. Or in making the presentation that looked the least like it came from a spreadsheet program.

The point of all this is that there is a basic question around all this that we do. It is, "Just because we can do a thing, does it mean that we should do it?" Or that we need to do it?

My suggestion is that you use post processing to get the results you want, then stop. Just don't worry about the stuff you don't need or care about. Have fun. Do lifr.
