Course Description
In this course freely available photo editing software will be provided for practical purposes in case you do not have access to software such as Photoshop, Paintshop Pro etc., although the fundamentals are not linked to any particular software.
You will be surprised how many otherwise useless digital images can be rescued or given a second life if you understand how to read colour channel information off a histogram and identify what information is still usable of the image to repair, modify or improve it.
I will also share my favourite free stock photo and image sources on the internet and provide ample practical examples to experiment with in each lecture to ensure you get hands on experience to cement in your newly acquired knowledge.
Who this course is for:
- Anyone editing photos and images in digital form
- Hobbiest and progressing photo editors
- Anyone taking digital images with a camera or phone

Almost all successful people will tell you that if you want to know what your are passionate about, ask yourself what you are willing to do right through the night, even if there is no big benefit, need or motivation to.
For me its creating a clear visual message using the right photos and images. Adding the right image to any presentation, blog post, online tutorial or website is what can keep me going for hours.
My photo and image editing skills made that possible and makes me strive to learn more and more techniques everyday to get to what I want faster. I also love finding new software and apps with which to do interesting things, but nothing beats that personal touch to an image.
Apart from being an engineer with most of my experience being in simulation and analysis and the sales and support thereof, I enjoy teaching complicated material and always strives to make things simpler and easier to learn to people who otherwise wouldn't.
Visual aids are always a great tool to help me transfer knowledge and sell a product. I have created many blogs in which I expose people to advanced technologies, to help them get started instead of deciding its too complicated right away. I love technology and can't help myself but to share it with others. I also know that today our human creativity is our biggest asset and heaven forbid that it would ever be possible for a computer to be creative too!

Well this is genius if you want to disect your images digitally and understand what the whole will be....sort of like anatomy. I would call this course the 'Anatomy of Digital Images.'
By Toni Price
This is a brilliant short course for enhancing your understanding of digital image colour.
Paul Naude maintained my interest easily throughout the videos and has managed to distil just the right amount of details for practical use. I have not yet been able to find this sort of information in such a concise format elsewhere. Explanations/examples were clear and well thought out. The only thing I felt slightly lacking was a more in-depth description of exactly how to colour-calibrate images for print.
All in all Thank You for a very worthwhile course!
By Steven Powell
Excellent course on understanding color and great insight into understanding and using histograms.
You need this knowledge to edit photos well.
By Erika Clarkson
I really liked the first half of the course and learnt a lot about light colour and print colour which was very interesting, but as another reviewer also mentioned, I'd have liked more information about the histogram and how to amend it.
I haven't yet downloaded GIMP which may be the reason I haven't fully understood the later course content. The reason being that I already have DXO installed and I have had problems with DXO not opening when I had another image editor installed at the same time.
