I thought it would be a good idea to list all the resources I have used throughout my photography journey. Everything here has been used/tested personally by myself. They have helped me in different ways and I hope they will do the same for you. Just so you know, some of these are affiliate links.
The grand master of all image editing software. Powerful and versatile, with many compatible third party plugins to boost your creativity. Photoshop + Lightroom are the gold standard image processing software in the industry. Get a 7-day trial for FREE.
Lightroom has to be my favourite tool to edit, organise and tag images. There are plenty of free tutorials on the internet to teach how you to use Lightroom to its full potential (not just sorting your images into albums!). I highly recommend getting the photography package deal for more value.
I have used Photomatix for my HDR ever since I started. I love the de-ghosting tool which removes ghosting created by moving objects in a few clicks. It comes as a standalone or plugin for Lightroom. You can get a 15% discount with the code "fotographee".
I use Color Efex Pro and Silver Efex Pro in my workflow frequently. It gives your image that extra oomph to make the transformation from ordinary to stunning! You can now get a 30-day trial for free.
