I recently embarked on an online photography course through "The Image Academy". I decided to work through it to learn from the basics up - composition, lighting, white balance, exposure triangle.......
I found the course really infomative, and have since went back and re-read some of the chapters to remind me of some of the core skills required for certain situations.
Part of the course requires you to submit an image portfolio for assessment. I am pleased to say mine was graded at Distinction level - well chuffed!!
I have uploaded them to a Flickr album, click on the image above to see more.
