Experimenting with long exposures. I need to figure out how to prevent the lens flare, more time behind the lens is needed.

experimenting with panoramic function i took loads of photos these were the best of the lot - i'll keep practising :)

for many years my garden was a shrubbery flic.kr/p/Lhv9ag which i loved. a picket fence covered in an ivy hedge coming down in a storm flic.kr/p/2gnCyih meant that over time changes had to happen flic.kr/p/2mn2x8a i'll be glad when the trellis is covered in honeysuckle and jasmine. that's the plan ...

Hasselblad 503CX, 60mm CF, Agfa APX 25, Rodinal 1+99, 60mins, agitate 1st minute continuously, invert at 30 minutes.
aka Brain Fart #2. Refer to Experiment #1 for an explanation. So I think compositionally the balance is a little out but I'm loving what's going on with the front of the building and tree. I'm thinking I might take this approach to some landscapes and see where it leads.
This was a shot I took at the IMATS Convention in Toronto and then decided to have some fun with textures and layers...
Heyy sexy ;D
Jk, Jk.
Though there is something I love about Halloween effects on PicMonkey...lol
Anyway, have you guys thought about what you want to be for Halloween?
Well this year, I'm going as a zombie nurse. I have thing for homemade costumes. They just seem more original :) My mom has agreed to let me have a pair of her old scrubs to tear up and mess with. Then I have a cheap-o makeup kit from the dollar store that has some thing i'm able to use. All I need is some more stage blood and a recipe for artificial wounds- and wah-la, I'm a zombie.
Geez, this seems longg.
So yeah c:
What will you be this Halloween?
Experimenting with product shots.
Heres one of my Nikon E Series 50mm 1.8.
The coating on this pops like hell!

Basic experiment on capillary fluid flow. Important for medicine, oil industry, safer fuel tanks, and much more...

I have experimented with this image to see if it succesfull to the Flickr audience.
I've found that I have slowly adapted to apprieciate the art of abstract photography, but I feel I haven't yet quite mastered the art. I would be hugely greatful if you would leave a comment to give your opinion on how the photo turned out. Thanks :)

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)."

This experiment demonstrates the shift in color from yellow-green to blue-green of minerals containing the uranyl ion in conjunction with carbonates.
On the right ~15mL of calcined garden gypsum (rinsed) was combined with 7.5mL of a boiling solution containing sodium chloride, sodium carbonate and uranyl nitrate in an aluminum form. The mixture released much gas (CO2 ?).
On the left ~15mL of DAP Plaster of Paris (containing CaCO3) was combined with 7.5mL of the cooled previously mentioned solution after it had been treated with HCl to remove the carbonate ions. The still acidic solution reacted with the CaCO3 in the Plaster of Paris mix and was mostly neutralized by the CaCO3 becoming CaCl2 and CO2 gas (and H2O). The mixture was left to set in a plastic form.

Much appreciation to Gordon Czop for the uranyl nitrate.

for a laugh you must watch this video sent to me by my dear friend Tao of Jonathan it is simply adorable and a guaranteed smile!
She has not been on Flickr in a while, so some of you may not know my sweet companion of fourteen years, yes this little beauty is fourteen years old..
We have welcomed many years together, and will do so again this New Year's Eve, with maybe a friend or two who may drop by for an egg nog.
Notice her littlefblack heart on her nose. It was not there the first year of her life, and one day it just appeared, honestly.
Have a great day,

Experimenting with creating vintage rail posters that were created over 50 years ago. A shot taken with my compact and processed in Photoshop
Not sure if quite got the style but maybe will progress this if I people take to it.
This is the sort of thing I am trying to replicate: www.travelpostersonline.com/inverness-lmslner--railway-tr...
I know this one doesn't look quite vintage if anyone knows the Forth Rail Bridge as it has these white covers on it, but you get the idea
