shadow and reflections of a pitcher of water painted in blue watercolor

teaching and learning
reflect each other like light
glancing off water

Here is a demo from yesterday's lesson. I painted this directly from a shadow cast by a glass pitcher full of water onto the paper. I drew the white lines in oil pastel following exactly the white reflections and refractions cast on the paper. Then I applied a blue wash in the darker shadow areas and a less saturated wash in the lighter areas. Off to the side of the pitcher image are little demo drawings in graphite using white oil pastel to blend. The two graphite rectangles were already on the page when I cast the shadow. Shadow drawings are an efficient way to capture a drawing shape on a page. The drawing doesn't have to be of the thing that's casting the shadow, for example, draw a shadow of a small weed with branches and you will have what looks like a tree depending on the scale of the other things in the painting. Shadow painting is a flexible tool for compositional play but now I really love shadow painting glass objects with water in them.

That is so incredibly cool! I'm going to try that technique this summer, sitting out on the balcony (does gin and tonic cast good shadows? :) ).

I so envy people who are visually creative, like you and my friend kadenza, a graphic designer. You are starting to inspire me to just play around with colour and form in spite of my very loud internal censor which says "But you don't know how to do this!" There is a rowing club near my new flat and I keep mentally converting the image of their crews streaking past on weekend mornings into streaky watercolours. When it's warm enough to sit outside perhaps I'll have a go.

Oh yes, gin & tonic is certainly a good source for bright glancing observations if The Great Gatsby is any indicator. You might mix 2, one to model and one to sip.

Wine works well too, of course more of a cadmium color. I have a an interesting photo from a summer trip to Toronto with Deanna. We sat at an outdoor cafe on Baldwin, and the light shadow interplay was so cool I wasted several photos trying to capture it. Probably in my storage in Austin however.

Looks like a fun exercise, I'll have to try it when i get my new paints.

Next time, can you post the image a bit larger, please. I would really like to see a more nuanced version. I know there are some interesting things going on that I can't see. Thanks. :-)

Thanks, this image is the size of my sketchbook 8.5 x 11 inches but most of my paintings really are small 2.5 x 3.5 inches. I'll try to keep the size more like the origninal. Unfortunately the sun went behind the clouds and I'm not able to make any more refraction pictures. I enjoyed your report on David Hockney's critique of new photography.

Monitor size is different than print size. Web sizes are always in pixels. Part of that has to do with the resolution of the image itself. Since PC and MAC has slightly different screen resolutions, the highest resolution that can be seen using a web browser is 96 dpi (MAC) or 72 dpi (PC). Your browser could be either 800x600 pixels (on an older machine) or larger, very often 1024x768 pixels (width x height). If you make an image that is 600 pixels in width, you'll have pretty much taken up the width of your LJ posting area. That is pretty large. 300- to 400 pixels in width is large enough to been seen by most here. If you wanted to show something with more detail then larger would be okay. Check thru images that people use here and see what the average is by right clicking then going to properties (on a PC). You can get image properties on the MAC too.

I have a little Mac laptop - the clamshell one - and I love it. It does have a small monitor but I can see those 600 pixel images in LJ you mention. I do my live journalling on a slow dial-up connection so I like to keep my uploads light. I routinely save all my pictures as 250 pixels wide and whatever height they are in relation to that width. It helps for me to maintain this pattern because I also use some of the images for my online portfolio. So, I am thinking of the single image in relation to a page with multiple images, my own LJ page, my portfolio, in other communities such as mail art or share-your-art, and of course, as they appear on my friends' friend pages. Anyway, that's the system I worked out for the many contexts these little things find themselves in. I'm glad you like the picture enough to request it bigger.

Let's see if this version works:-)

Yes, that is much easier to see. There are so many things happening there. I like it a lot!
