Moon Pastel Sketch *Nov 9 '08 -New Photo vs Old +
      #3405648 - 10/23/09 06:30 AM



I hope I am not boring any of you with these year old repeats. This was my personal favorite to date last Nov 9 ’08 of the moon. It was also the largest lunar disc at 15 inches that I attempted to sketch up to that date in under 2 ½ hours; with a break of a 4 hours at mid evening due to clouds and rain. The rushed haste to dodge clouds caused me to be quick and impressionistic so it is rough in surface areas but I think I got the terminator close to accurate. None of the surface was cleaned or altered in Photoshop of smudging or smears as you can see, especially the black space background. This sketch was produced on 19”X 25” Strathmore Artagain paper. I later added the text to the lower right area since the original photo was taken last November as someone later called for text info to be written on the sketches. The new photo was cropped to enlarge the lunar disc as much as possible for CN viewing.

What follows are two additional sets, one set has close-up insets of the region from Tycho to Mare Humorum comparing each old and new photos. The other set is to show an anomalous or apparent stereo 3~D. The new photo shows the actual chalk color overlaying and underpainting especially in the mare regions. Rich was right in that post about producing and viewing 3~D , you have to use a little crossed eyed technique, but relax and don’t fight it! It actually works!

I should point out that these two above are only for comparison of the new and old photographic images and not intended for 3~D Stereo imaging, as the close-up inset thumbnails do not properly line up for the stereo imaging. *The stereo image would be in the following third window below. >

To properly see 3~D, adjust eyes about 12 inches from the screen, relax the eyes to gently cross *or focus beyond the page to the distance in the room, then hold that focus and move the eyes to the screen; a third image will appear to the right. Then continue to focus on the center [3~D] image of the three. -M

Hi Mark,

this moon above is my absolute favorite. This is an ART-MASTERPIECE wich schould be framed to be an eye-catcher in a living or buisiness room. It would be a challenge for all visitors to see the 3D effect. This will open the visitors mind. Respect and my personal congratulations.

Thanks Paul

I'm glad you like it.

I need to consider someone to make full size quality prints soon of a few of my original images. As soon as I determine the actual printing process.

Mark
