I watched the tutorial and did the exercise along side. I really learned a lot about the workflow Matt Kohr shows. It is really easy to understand and teaches very interesting facts about light. I totally recommend this video.
Here is the link to the video: http://ctrlpaint.myshopify.com/collections/frontpage/products/basic-photoshop-rendering
This is my blog.
I will share information about workflow, my insights into image-making or just general thoughts and rants about being an artist.
