It is really interesting to adopt PS and lightroom to do some simple photo retouching. Most important thing is that you have these programs being installed or you can afford to use their cloud services. There are a lot of programs on Youtube which can allow you to learn the simple technique.
Other points to be noted:
- Shooting in RAW format. Jpeg format is not suggested.
- Be patient to learn.
- Practice make perfect.
It is not difficult to change the climate being show from summer to Autumn.
It is not difficult to change the photo from Autumn to Wonderful Land too.
