A Fomapan Action 400 black-and-white film to test the effect a the special Foca filter "Dyma" produced in France in the 50's.

The filter is called "Dyma" due to the presence of neodymium in the glass giving an unusual absorption by bands in the visible spectrum. In particulier blue and yellow color ans more absorbed than the rest of the spectrum. The filter existed in two different versions with the coefficient x2.5 or 3.5. Here the 42mm push-on Foca Dyma filter used is a x 3.5.

As a consequence, I exposed the Foma 400 for 80 ISO using a Minolta Autometer III with a 10° finder for selective measurements privileging the shadow areas. I used my FOCA camera PF2B year 1956 and its normal Oplar lens1:2.8 f=5cm equipped for all the views with the Dyma filter and a Genaco metal shade hood.

Typical settings during the session : 1/100s f/8 to f/11.

After exposure, the film was processed using Adox Adonal (Agfa Rodinal) developer at dilution 1+25, 20°C for 6 min.

The film was then digitalized using a Sony A7 body adapted to a Minolta Auto Bellows III and a Minolta Slide Duplicator using a lens Minolta Bellow Macro Rokkor 50mm f/3.5 at a reproduction ratio of 1:1. The reproduced RAW files obtained were processed in LR prior the the final JPEG editions.

All views of the film are presented in the dedicated album either in the printed framed versions and unframed full-size jpeg.

About the camera and the lens:

The Foca type PF2B (PF for "Petit Format") was constructed in France by the company "Optique & Precision de Levallois" (OPL) starting from 1947. It was manufactured in the Chateaudun OPL factory, route de Jallans, France, in 1956 among a late series of the PF2B. The factory, constructed in 1938, is still at the same place under the name of SAFRAN now producing precision devices for aerospace appliances.

The camera is equipped with the collapsible OPLAR lens (a Tessar formula) 1:2.8 f=5cm. The focal shutter of the PF2B has timing of 1/1000, 1/500, 1/200, 1/100, 1/50 and 1/25s plus the B pose. A slow exposure device below 1/25s could be installed by the aftermarket service and was installed basically for the FOCA PF3 and Foca Universel.

My body does not absorb B12.

The part of your intestine that absorbs it is the one part of my intestine that has active Crohn's.

So every three months I get an injection with one of these ampules of Neo B12.

I am off to the specialist tomorrow, so I picked these up today.

And being cute like they are, I couldn't resist a photo.

A particularly colorful case is the star forming region SH2-29 (Simeis 188) which houses an unusual and bright cloud arc cataloged as NGC 6559. Visible above are red glowing emission nebulas of hydrogen, blue reflection nebulas of dust, dark absorption nebulas of dust, and the stars that formed from them. The first massive stars formed from the dense gas will emit energetic light and winds that erode, fragment, and sculpt their birthplace. And then they explode. The resulting morass can be as beautiful as it is complex. After tens of millions of years, the dust boils away, the gas gets swept away, and all that is left is a naked open cluster of stars. SH2-29 is located about 4,000 light years away and can be found about one degree northeast of M8, the Lagoon Nebula.

At the center of the image placed IC 4685 nebula. Black "worms" over it are dust nebulae B 302 and B 303. NGC 6559 is slightly to the right of the center and “separated” by an arch from IC 4685. Two spherical clumps just below the center are IC 1274 and IC 1275 (SH2-32 and SH2-31 respectively), separated by the dusty nebula B 91.

On the left side of the frame there is a small reflection nebula IC4678, and on the bottom of the frame - IC 4684. In the bottom left corner is the open cluster NGC 6546.

In the upper left corner in the frame is the northeastern part of the Lagoon (M8). Interestingly, against the background of SH2-29 nebula, just above the center, the planetary nebula Minkovsky M1-41 is present.

The Fraunhofer b-band triplet in the solar spectrum is stronger than might be expected from a non-resonance (subordinate) line. In the energy level (Grotrian) diagram in the top panel above (US Department of Commerce, National Bureau of Standards, NSRDS-NBS 23, "Partial Grotrian Diagrams of Astrophysical Interest", p16), the lower level of the b-band triplet absorption is seen to be 3p 3P0 which has no permitted transition to the 1S ground level.

The spectrum below shows, marked in green, the analogous triplet absorption in the ultraviolet, 3p 3P0 - 3d 3D, at 3838.3, 3832.3 and 3829.4 which is also strong.

For these transitions, the 3p 3P0 level becomes a pseudo-ground state.

I have now found and posted the plots of all the Mg I lines in the Grotrian diagram that are within the HARPS spectral range. The only one not to show is the 4081.83Å intersystem line.

This plot - a combination of nir and ir observations of the transmission spectrum of blue topaz ( Al2 SiO4 (F,OH)2 ) - shows two of the absorption lines (961 and 1400nm) from the OH vibrational modes in the crystal. These are analogous to the stretching modes of the water molecule and so correspond approximately in wavelength to the water bands that have the bending mode quantum number nu2 = 0.

My photowalk with my Semflex Standard 3.5, a French TLR camera year 1959, Lyon, France June 18, 2024.

The camera was equipped with a Semflex yellow filter x2 and the Semflex metal shade hood. An Ilford PanF+ 120 film was loaded and exposed for 32 ISO (Instead of 50 ISO to compensate in part the filter absorption) using a Minolta Autometer III equipped with a 10° finder for selective measures privileging the shadow areas.

Typically I used the 1/100s (one at 1/50s) with aperture ranging from f/8 to f/4.5.

After the view #12 exposed, the film was fully rolled to the taking spool and was developed in a Paterson tank with a spiral adapted to the 70mm large film. 500 mL of Adox Adonal (Agfa Rodinal) developer were prepared at the dilution 1+25 and the film processed for 6min at 20°C.

Digitizing was made using a Sony A7 camera (ILCE-7, 24MP) held on a Minolta vertical macro stative device and adapted to a Minolta MD Macro lens 1:3.5 f=50mm. The light source was a LED panel (approx. 4x5') CineStill Cine-lite fitted with film holder "Lobster" to maintain flat the 70mm films.

The RAW files obtained were inverted within LR and edited to the final jpeg pictures without intermediate file. They are presented either as printed files with frame or the full size JPEG.

About the camera and lenses :

New in my camera collection this French Semflex TLR year 1959-1960 equipped with f=75mm SOM Berthiot lenses.

The SEM company ("Société des Etablissements Modernes de Mécanique") was founded in France by Paul Royet in 1946, in the small city of Aurec near Saint-Etienne (Loire). The SEM camera's was known essentially for the TLR Semflex that were a great commercial success in France until the 70's. The camera's are constructed around an injected aluminum alloy chassis, very resistant and rigid permitting precise optical alignments. The focusing mechanism is made of a cam system like the Rolleiflex giving an accurate and smooth focusing. SEM constructed their own shutters called Orec with 5 leaves capable of the 1/400s to 1s with B.

Semflex received in majority French optics Berthiot with 3 or 4 lenses (Tessar type). Some camera's were also mounted with Angénieux lenses.

Semflex were trusted TLR camera's used by amateurs and for professional purposes. From 1949 to 1976, 171.000 Semflex were produced in many different types and versions.

My Semflex in a middle grade version Standard 3.5 type-10 (1959-1960). It was the last version mounted with the 3-lens SOM Berthiot 1:3.5 f=75mm. I got the camera with set of accessories and several documents including the user manual of the Semflex Standard 4.5 versions. The accessories include a leather SEM ever-ready bag, a Semflex push-on shade hood, a Semflex push-on yellow filter x2 in its original box, and close-focusing lenses. The 1D one is constructed with a prism for the finder lens that compensates the parallax in the zone 1m to 0.5m.

The decorative ring around each lenses can also receive push-on accessories in 36mm diameter as the FOCA or Leitz 36mm filter series. I adapted two protective lens caps from Kodak film canister snapped covers.

i can't wait to get out of high school,

invisible from all this self judging and absorptions.fake friendship and hope.

feeling like everyday is the same.

away from thinking of whether you fit in or not, just away.

the one song that can describe completely how i feel about highschool is that one song from jimmy eat world which is work

im tired of feeling this, this responsibilities and expectations.

stuck in the same hell hole for 4 complete years had made me dry.

now the lyrics:

If you only once would let me

Only just one time

Then be happy with

the consequence

With whatever's gonna

happen tonight

Don't think we're not serious

When's it ever not

The love we make is

killing its take

A game to play along

this is one of the songs,i put on repeat for the pass 3 years.I told you i really do recycle my songs. I love this band only because of one song, nothing beats what they're trying to say.

i guess teenage years are the years you learn from everything. Trying to absorb and absorb your surrounding and being you in the end,i think thats the fuking point of it all.

some one important in my life once said 3 years ago:

Be yourself, don't take anyone's shit, and never let them take you alive...

thanks for changing my life,

and being the source of being true to myself throughout high school, i dont know how i had survived that long without being someone else.

:)

i want this to be a good closure of that chapter in my life.

tie all loose ends.

resolve all things unsaid and undone.

being inspired all the time just by passing through the same road.

not giving up with people.

not giving up with yourself.

love your family endlessly.

appriciate your friends.

walk this world and never feel alone.

and most importantly,

being thankful for all the second chances given.

Fuck hipsters.

What's with them never showering, thinking they're hotter than regular people, and no-job-having? I don't get it. I just don't get the hipster thing.

And yet, despite how much I resent them, I constantly find myself drawn to their self-absorption, their belief that they are cooler than other people is SO STRONG that eventually, you kinda start buying it too. It's WEIRD.

But it totally works. So, this card will remind you of all the shit you hate about hipsters.

This is a slightly worn fragment of iolite approximately 24 x 18 x 11 mm. This transmission spectrum is measured along an intermediate axis where the colour is a blueish-white. The absorption line positions are marked here from previous measurements.

The image is a 15 exposure focus-fused set taken with the camera - at f/13 - mounted on a mechanical track.

Iolite is sometimes known as 'water sapphire' for reasons that are apparent from this image.

Vibrational spectroscopy is an analytical technique that provides information about molecular structure, chemical bonding, and intermolecular interactions. Infrared absorption and Raman spectroscopies are well-known examples of this widely used form of spectroscopy. VISION uses neutrons rather than photons as a probe of molecular vibrations. This approach has several advantages over optical spectroscopy, including high sensitivity to hydrogen, absence of selection rules, ease of computation of the vibrational spectrum, isotopic sensitivity, no energy deposition in sample, and high neutron penetrability through bulky sample environment.

Applications

VISION can be used for leading-edge studies in disciplines such as nanotechnology, catalysis, chemistry, biochemistry, geochemistry, and condensed/soft-matter science. Contemporary popular themes comprise hydrogen storage, hydrogen bonding, molecules adsorbed on surfaces and porous materials, thermoelectric and photovoltaic materials, hydrous minerals, metal-organic frameworks, drugs and pharmaceuticals, polymers, proteins, catalysis, and batteries.

The environmental impact of a green roof is undenyable, and adds significantly to the LEED Point system designed by the USGC in all five major areas: sustainable site development, water savings, energy efficiency, materials selection, and indoor environmental quality. Green roofing replaces the green space displaced by a building, prevents excess storm water drainage, reduces the temperature of a building and the urban heat island effect, protects and extends the useful life of a roof, and reduce energy demands.

What's more, a green roof incorporating AirDrain means your design includes renewable, recycled, and locally obtained materials. We know you have a choice in designing a green roof, and we hope you consider the many benefits of AirDrain.
