This is the third and final lightfastness test of the Lukas Aquarelle watercolor paints (original post, first update, second update). The reason for ending the test is twofold, the test strip was in the way of a window I wanted to start opening, and after ten full months of Arizona sun the verdict is in. I first hung the test strip in January 2016 in a south facing window. Expecting the paint to be faded out before the first 100℉ (38℃) day.
This is one project that seems to slip through the cracks when it comes to doing regular updates (original post, first update). The irony is that the more I forget about it the better the comparison becomes as I leave the test strip in the sun longer. This time it’s been 18 weeks since I first hung the test strip in a south facing window. This weekend is probably the last one of the spring that will see the daytime highs staying under 100℉ (38℃).
Just testing the 7D Mark II’s wireless flash control. I really like that it can control my 430 EX II from just the popup flash. The system is pretty slick, with several choices: Built-in and external controled via the ratio of each to the other. External only. Both but with independent exposure compensation for each. This is my cat with the 430 EX II at lower right with a 3:1 ratio to the popup flash.
I originally planned to do more frequent updates on this, but found that there wouldn’t be much to report. It’s been two months since I hung the test strip in a south-facing window. During that time we’ve had one of the hottest Februarys on record. Test strip in window. For a quick review, see the first article in this series. Here’s the side-by-side scan of the two halves. Scan of both halves.
Lukas Aquarelle 1862 watercolors are a european brand that is sold in North America by Jerry’s Artarama. Being a low-priced paint, I wondered about the quality of the pigments. So I decided some testing was in order. I bought the following five paints: Alizarin Crimson (1064), Gamboge (1016), Ultramarine Light (1135), Burnt Sienna (1109), and Phthalo Green (1195), in half pans in a Jerry’s store. I have no idea how long they were sitting on the shelf or when they were made.
