This is just a test shot to check if my camera is working and if I've inserted film right. I think they retouched my photos in the photo lab which well, sucks.
Testing, Testing, ... BANG!!!
Nondestructive testing
Nondestructive testing or Non-destructive testing (NDT) is a wide group of analysis techniques used in science and industry to evaluate the properties of a material, component or system without causing damage.[1] The terms Nondestructive examination (NDE), Nondestructive inspection (NDI), and Nondestructive evaluation (NDE) are also commonly used to describe this technology.[2] Because NDT does not permanently alter the article being inspected, it is a highly valuable technique that can save both money and time in product evaluation, troubleshooting, and research. Common NDT methods include ultrasonic, magnetic-particle, liquid penetrant, radiographic, remote visual inspection (RVI), eddy-current testing,[1] and low coherence interferometry.[3][4] NDT is commonly used in forensic engineering, mechanical engineering, petroleum engineering, electrical engineering, civil engineering, systems engineering, aeronautical engineering, medicine, and art.[1] Innovations in the field of nondestructive testing have had a profound impact on medical imaging, including on echocardiography, medical ultrasonography, and digital radiography.
Methods[edit]
NDT methods may rely upon use of electromagnetic radiation, sound, and inherent properties of materials to examine samples. This includes some kinds of microscopy to examine external surfaces in detail, although sample preparation techniques for metallography, optical microscopy and electron microscopy are generally destructive as the surfaces must be made smooth through polishing or the sample must be electron transparent in thickness. The inside of a sample can be examined with penetrating radiation, such as X-rays, neutrons or terahertz radiation. Sound waves are utilized in the case of ultrasonic testing. Contrast between a defect and the bulk of the sample may be enhanced for visual examination by the unaided eye by using liquids to penetrate fatigue cracks. One method (liquid penetrant testing) involves using dyes, fluorescent or non-fluorescent, in fluids for non-magnetic materials, usually metals. Another commonly used NDT method used on ferrous materials involves the application of fine iron particles (either liquid or dry dust) that are applied to a part while it is in an externally magnetized state (magnetic-particle testing). The particles will be attracted to leakage fields within the test object, and form on the objects surface. Magnetic particle testing can reveal surface & some sub-surface defects within the part. Thermoelectric effect (or use of the Seebeck effect) uses thermal properties of an alloy to quickly and easily characterize many alloys. The chemical test, or chemical spot test method, utilizes application of sensitive chemicals that can indicate the presence of individual alloying elements. Electrochemical methods, such as electrochemical fatigue crack sensors, utilize the tendency of metal structural material to oxidize readily in order to detect progressive damage.
Analyzing and documenting a non-destructive failure mode can also be accomplished using a high-speed camera recording continuously (movie-loop) until the failure is detected. Detecting the failure can be accomplished using a sound detector or stress gauge which produces a signal to trigger the high-speed camera. These high-speed cameras have advanced recording modes to capture some non-destructive failures.[5] After the failure the high-speed camera will stop recording. The capture images can be played back in slow motion showing precisely what happen before, during and after the non-destructive event, image by image.
This was the first roll that I put through the TLR that I picked up on the cheap via eBay.
On first viewing, the thumbnails are quite promising, but a not-so-close look quickly reveals my hopeless inability to operate the focus mechanism.
Lesson learnt.
Bring on film two!
Testing long exposures with the 2nd backup camera. Garbage night at Grandma's house. I liked the results enough to share this test shot. 3min exp approx 1.5 hrs after sunset.
Testing out the M.Zuiko 7-14mm Pro on a cold morning in Whitehorse. At 7mm, this lens is the equivalent of a 14mm lens on a 35mm camera. That is pretty wide! Here, I shot it wide open at f/2.8 on the OM-D E-M1. It was a very cold morning but the lens performed better than my fingers which rapidly froze up in the chilled air.
In this photo, I am looking across the Yukon River towards downtown Whitehorse. That said, the cold mist rising off the river is obscuring most of what would otherwise be visible on the far side of the water. The moon was huge on this morning and is still visible to the middle right of center despite the 7mm focal length.
Testing my 'Gift' MPP Microflex TLR for COLOUR on the Taylor-Hobson 77.5 mm f3.5 'Micronar' lens now it has all been cleaned. I used a half-used cut roll of very old Kodak Gold 400 GPY film rated down to 100 ASA and home-processed in C41 for longer time. Scans had a 'Blue' cast but I corrected in FastStone Image Viewer.
Almost ready to test ;) Gear is mounted into a temporary test jig to ensure proper clearance and operation.
I'm shooting a couple of couples for their prom tomorrow, and needed to test the fog machine setup in my brother-in-law's garage, where I have the lights set up.

This is a test shot.
It wanted to blacken the background, and to confirm where the model comes.
However, because it is not a digital camera, it is not possible to confirm it. It is likely to have helped to taking a picture with the twin-lens reflex camera if it was possible to confirm it.

Not often you see three Harleys waiting for their annual Ministry Of Transport test , especially in a small town like Crickhowell . The 1970 5oo twin Triumph T100 Daytona looks like it may need a bit more work in the headlamp area though !
This garage obviously specialises in classic bikes as the shop window had a nice looking Suzuki GS750 four and a smaller two stroke for sale.

An old school TV test pattern. This is the type of test pattern I remember waking up to when I was young and there was no programming on yet, I would stare at it until something came on - usually at 6 AM.
Another test piece I made to verify my flaperon design/parts. Looks good to me!

Had to get a haircut since I keep testing lights on myself and uploading the pics. I really like how the light turned out on this one. Taking pics at midnight again and editing until 3am.
Let me know what you think of the lighting and editing.
Nikon D5000
Lens: AF-S DX Nikkor 35mm f/1.8
Lighting: Promaster 16" beauty dish with promaster 7500EDF flash for main light. A bare blue gelled flash camera left and back. Another flash gelled purple shot through an umbrella camera right and in front of subject.
