This is inspired from WhateverMars photostream. He has a multicolored wheel using this design and I thought what a neat way to quickly compare color combinations. I want to make one using every color for the base. I just wish I had more colors available to me - right now there are many shades missing, perhaps even enough to create a wheel. Sadly this is the extent of my colors, but I thought it made for an interesting photo.

For me, fashion is a form of art. I wanted to take the time and experiment with some styles and colors to se what works and what doesn’t. Feel free to comment on what styles you think work best 😃

Connectivity and readymade.
Experimenting, manipulating and combining daily life objects in order to attempt, to force or to mystify a workable connection between them, at least to make it visible and/or possible. This exercise is to be considered as a warm-up, a first step towards a further installation or project.

and I spent WAY too much $$ on Matilda Jane stuff so all of it WILL get photographed at some point... LOL
My thing is that i doubt the sincerity of some of the comments with group icons that I receive...and think that maybe some people send invites and comments with group icons so I can return the favor. I do like a lot of different styles of photos..as you have seen , i like colors, sepia, black and white, minimalism, abstract etc... so i enjoy a lot of people's photographs. However, my experiment was to see if i could handle to post to as many groups as possible...and to see what the response was ( i reposted this shot to 17 groups..and got much more response from it that when I originally posted it about 4 months ago, flickr.com/photos/deegoo/2378441759/?addedcomment=1#comme... when I had not sent it to any groups at all...but it is really too much work and kind of ruins the pleasure of enjoying flickr ). I like it when people do comment personally...i am not too crazy when some people just leave the group icon, which happen about half of the time, or when people just fav and run.So, i will stick to posting to some groups and a core of flickr friends, which is basically what I was doing ! Thanks again for participating in this experiment !
I am looking forward for all of you to stop by and check to see what I am going to come up with in the near future ;-)
We all have to find our own balance as one of my good flickr friend just said to me ;-)
Have a wonderful Life !
Not my usual brand of work, but i wanted to try something more processed using a strobe flash and more of a studio setting... I'm pretty pleased with how my mad scientist portrait turned out, but am welcome to any constructive feed back.

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.

Okay, so maybe I just didn't go far enough on my previous fighter mode? What if the legs don't transform into engines, but into ultra-heavy beam cannons?
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. :-)
...The students conducted some experiments some time ago, so I experimented some on the photos in the new PS Lightroom...
I thought I would try a back lit subject since everything was already set up and in place. (I just moved the side light to the rear, along with the other strobe already in place, to reflect off the white backdrop and on to the bottle.)
Camera RAW image made with a Nikon D7100 camera fitted with a 60mm Micro Nikkor lens. Basic post-processing (camera and lens profiles, white balance, and initial level adjustments) made with Adobe Lightroom Classic CC.
This is an experiment, I am trying to combine low-res textures with high-res vectors.

This experiment demonstrates the shift in color from yellow-green to blue-green of minerals containing the uranyl ion in conjunction with carbonates.
~15mL of DAP Plaster of Paris (containing CaCO3 and SiO2) was combined with 7.5mL of a NaUTC (sodium uranyl tri-carbonate) solution and allowed to set in a mold.

Just an experiment with a long exposure, plus Luminance using the actual NEF raws and 'bracketed' exposures. Gimp 2.8 for layer adjustments and the like. Not a hugely interesting subject but again just experimenting whilst bored with time to kill. Input welcome.

This experiment demonstrates the shift in color from yellow-green to blue-green in aqueous solutions of pyranine when made acidic.
The fluid from a yellow hi-liter pen was removed and mixed with water (shown in the center test tube). The left test tube contains that solution with 1 drop of muriatic acid added. The test tube on the right contains the solution with 5 drops of a sodium hydroxide solution.
The pH of the left test tube was ~1 and the right test tube ~14. It was hard to measure the pH of the solutions since it dyed the pH indicator paper yellow.
Upon adding the drop of acid to the pyranine solution, it changed from yellow green to clear. This was because the pyranine had been protonated (provided a hydrogen ion) which reduced the absorption of light at 450nm.
Refer to this article: www.ugcfrp.ac.in/images/userfiles/30241-CPL_399_147.pdf
"At a pH less than 7, the absorption spectrum of pyranine
(HPTS) exhibits a peak at 405 nm which is ascribed to
the protonated form (ROH) while at a pH greater than 7 the
absorption spectrum exhibits an additional band at
450 nm arising from the deprotonated form (RO)."

Photos were taken at Biological Academy in Dalat city, Vietnam. I found this place is really awesome with its creepiness. Though sunlight fills the whole mansion, shadow still lurks in very corner that I accidentally turned around.
