i am experimenting with a certain style of sbl mouth, after i fell in love with a YJ custom,....well, it isn't exactly what i wanted, though i am more or less happy with the results.
Still deciding about this girl's future (initially, my own sbl)
While thinking about lenses, I'm playing with old ones. I think next time, I'll pull out the tripod and think a little more about what I'm doing.
Experiment: cropping photos in a triangle, with a duotone which in my opinion matches the setting and composition of the photo.
For my next step in this experiment I'd like to make prints, cut out the triangle, and glue them to foamboard.

Uranyl nitrate and sodium chloride from a previous experiment was dissolved in water. Approx. 6mL of this solution was added to ~5mL of dry sodium metasilicate along with water in a small watch glass. This was rehydrated every few days for about two weeks as the sodium silicate would crystallize and then dissolve again. At the end of the two weeks it was dried under a small electric light bulb resulting in a clear glassy substance with a tinge of green color. On the surface formed large crystalline layer. Before the substance dried it was not very fluorescent. After drying and crystallizing, it became very fluorescent yellow-green under all UV wavelengths.
Because of the crystalline nature of the substance, I don't think I succeeded in creating hyalite opal which is amorphous and not crystalline.

Much appreciation to Gordon Czop for the uranyl nitrate.

This experiment was an attempt to recreate the fluorescence of chromium activated corundum (aka 'ruby'). Aluminum hydroxide was mixed with 1-4 drops of Cr(III) oxide in a basic solution. This was placed on a small amount of aluminum sulfate in an aluminum foil container and a bit of water was added.
The sample was then heated, first with a propane torch until the water was removed and then with a MAPP gas torch until the aluminum sulfate expanded into foam, trapping the aluminum hydroxide which was calcined into aluminum oxide by the torch's flame. (at least that was the plan)
Shown also is a natural ruby from Mysore, India.

A Photoshop experiment using gradients, layers and solid colors.
The watch is an early Limes Nightflight. I also used my 50mm 1.4
Manual Nikkor which will be getting more regular workouts so I can
learn to focus it. :-)

Uranyl nitrate solution was used to hydrate 15mL of DAP Plaster of Paris mix. The result showed hardly any green uranyl fluorescence, what could be seen was yellowish green. The plaster was then rehydrated using a concentrated sodium carbonate solution. The water was evaporated and the mixture was then calcined at ~150 degC for 4 hours in an oven. It was then rehydrated using a sodium carbonate solution. The plaster mix bubbled for about a half hour releasing much CO2 gas. After drying a coating of yellowish crystals formed on the surface.

I'm trying to find a doll which can be attached to a card or a book art page. These are the first tries and involve lightly stuffed dolls and complete "flatties"
I will decorate them and see how we go. Great fun!
This photo was mainly an experiment to see how close I could get to this dragonfly that was hanging around my backyard one day last summer. I sat on the ground and kept sliding forward a little bit at a time (this shot is 18-24" away). Every time I would get too close and scare him off, he would fly around the yard and then come land right back in front of me with this pose. This happened many times throughout the day and was pretty cool! (Non-HDR photo)
In teoria stavo cercando come ottenere l'effetto Dragan, poi mi è saltato fuori questo strano hdr in bianco/nero...

A buddy of mine was asking if I had any thoughts about how to mill flutes and have the cut start or stop with a nice tapered end. I had the idea of rigging up some kind of cam to ramp the cutter into and/or out of the cut. I just did a little experiment using a tilt table as my cam. It works!!!

On an aluminum tray, salt, sulfur were heated until the salt was melted. The frozen salt contained sulfide and possibly, disulfide ions. This was then added to a solution of sodium silicate and dissolved by boiling the solution.
To this solution was added another solution containing sodium chloride and aluminum sulfate. When they combined, a white precipitate formed. This was strained and dried, then melted with a MAPP gas torch.

My project for this week-end: Testing eco-friendly clays. This boy is mainly consisting of food starch and plant fiber. He's inspired by artist Zao Dao's character "Crow Teeth".
