Just to update.

I’ve been using Lightroom for some while now, and have learnt a lot from watching a series of tutorials on Youtube.
It is very easy to overdo processing, but it can turn an otherwise pretty ordinary JPEG image, into something altogether
more presentable when shooting and processing a RAW image.
There will be those who argue that JPEG is fine, and that you should get it right in the camera. I doubt there’s a photograph
published, which hasn’t undergone some tweaking. Even going back to monochrome prints in the darkroom.

Pressing the shutter button is only half the job.
