Test roll 1 from the Canon EOS 3. There's a bit of a learning curve, but all in all, I'm happy with the purchase. My portraits from this roll turned out the best.
There does seem to be a tendency to overexpose, which I'll need to work on.

On approach to Rothesay HarBour, Isle of Bute.
MV Argyle, is a ro-ro ferry, owned by Caledonian Maritime Assets Limited and operated by Caledonian MacBrayne on the route between Wemyss Bay and Rothesay (and sister ship to the MV Bute. (Superficially there is very little to differentiate Argyle from Bute. Argyle has a second lift from the car deck and the passenger lounge is a little larger than on her sister.) MV Argyle has a semi-open car deck with a clearance height of 5.1m. Like the MV Coruisk before her, she has bow and stern access and in addition she has a starboard vehicle ramp aft which was used at Rothesay before the pier was converted to allow end-loading.
Built in Poland , and bought for £9 million, she is the seventh Clyde ship to have the name Argyle. Until 2007, there had not been an Argyle on the Clyde for over a hundred years, but the present vessel is the seventh of the name. The first was a paddle steamer built only two years after the pioneer steamship PS Comet appeared on the river in 1812. The second was commissioned in 1815; the third and fourth had connections with Loch Fyne, while the fifth was a cargo steamer sailing to the Outer HebrideS.

Testing out a Roll of Adox Colour Implosion film shot at 100 ASA using a Nikon F3HP camera, and Nikkor Ai 50mm f/1.4 lens
The film (and prints) look this bad on purpose, when shot at 100 ASA, the film has a definite blue cast, shot at 400 ASA, a Red cast. When I picked the film up from the lab, they thought I'd been shooting 30 year old film, rather than new film.

Today, I took my 85mm ƒ/1.8 lens out for a little test session in the real world. I set up a tripod off the side of our local Catholic church, and proceeded to shoot the same scene with AF on, in AE (shutter priority) mode, with shots starting at ƒ/1.8 and going all the way to ƒ/22 in 1/3 ƒ-stop steps.
The objective was to see where optimum sharpness was to be found; as a bonus, I also learned how chromatic aberration behaves in this lens.
Peak sharpness is, without any question at all, found at ƒ/6.3, in the image you see here. Sharpness is excellent at ƒ/4, then shows small increases up to ƒ/6.3. Then sharpness begins to roll off gently at ƒ/7.1 and ƒ/8.0, shows a distinct though not yet highly objectionable decrease at ƒ/9.0, and the absolutely takes a dump at ƒ/10. This makes a lot of sense to me because with the 50D's 4.7 um pixel pitch, diffraction begins to take effect at ƒ/7.6 (not an available setting on the 50D, btw) and by ƒ/10, the Airy disc has far exceeded the diameter of a single sensel — so we're well into diffraction-caused blur by ƒ/10, regardless of the len's other sharpness-related factors.
Chromatic aberration is strongly evident (mostly at the left edge of the large tree at foreground center where the dark tree intersects the well illuminated concrete of the building at this angle) starting at ƒ/1.8, and reduces just a little bit with every 1/3-stop taken until ƒ/13, where I cannot see any remaining purple fringing. Unfortunately, this is far beyond the objectively determined peak sharpness of the lens at ƒ/6.3. If you look at the tree in this image, you will see some CA.
So... in high contrast situations where I feel I can give up some sharpness, I'll be thinking ƒ/13, light permitting, and when I'm looking for max detail, it'll be ƒ/6.3 to about ƒ/5.6. The best compromise -- the setting where sharpness has not fallen off much and CA reduction is as high as possible at the same time -- is about ƒ/8.
This image, as far as I can tell, demonstrates the best sharpness that can be shot with this lens and camera. It is a consequence of:
EOS 50D, Canon EF 85mm ƒ/1.8 USM prime @ ƒ/6.3, ISO 100, 1/200th sec. exposure, tripod, 2 sec shutter delay.
RAW to JPEG conversion with Aperture.
The controller is partially functional- red and blue are working on the first four channels. This is all being driven by the parallel port so expect lots of flicker as the computer gets busy :-)
This is a test series with my new toy: Sigma 18-250mm DC OS HSM. I used to have the prior version (18-200) and I think it is a very nice "always-on" travel lens.

The Nevada Test Site is owned by the Department of Energy and is the largest known energy research area in the world.
Ce bunker sur Frenchman Flat a résisté aux explosions de l’opération Plumbbob. Les archéologues n’ont pas pu encore en visiter l’intérieur. Ils attendent que les services de sécurité procèdent, plus de 40 ans après les tests, aux mesures de radioactivité.
These are for a project-in-progress, but I like the way they were subconsciously assembled when I moved them.

This is one of the test stands at work. They used to test SSMEs on it, but now it sits as a monument to what it once was.

Human test Subjects are used everyday
All over the world Some are Willing participants who get paid , While others just pay the price !

The Harsh reality of Mankind's search for Power and wealth, does go to far sometimes. sometimes in the name of money , sometimes in the name of National Defense ,sometimes just in the guise of a "Greater Good"
Private companies run studies And a lot of this type of research is done using Low income people ,students,also Military recruits in the United States but is also prevalent in India ,Europe, Asia,
This is a $14 billion dollar Industry in the united states alone
I am not totally against Human testing as long as the participants have full knowledge of whats going on and are completely willing
But The question is " How Far is to far ?"
And who gets the job of making sure that everyone is Playing by the "rules"
what will the punishment be for someone who breaks the "rules" ?

This was just a test shot to make sure my camera settings were right, but Ava decided to smile anyway.
