Proper lighting plays an important part in the creation of art. It is as important as quality supplies for an artist. There have been many times that I've continued worked in poorly lit rooms thinking it was not a big deal. Why would I not just get up and open the blinds/curtains or turn on more lighting? My eyes adjust to the condition of the room, and I believed that I was able to see just fine. Sometimes, it was because I was too lazy to do a simple thing like flipping a light switch. Other times, I thought I was skilled enough to create in the diminished conditions. It wasn't until the work was brought into the light that I could see the glaring issues precipitated by lighting. At times, the issues were minor things that could be easily fixed. However, there have been times that I'd have to start completely over because the issues were too great to be fixed.
Allowing ourselves to believe we are "ok" to continue in the darkness will create issues that will have to be dealt with at some point.
