The final selection and other pictures

The following images are my final selection for the end of course assessment. The theme here is "reflections". I've also included some images that did not quite make the final cut. The most frustrating aspect of the course for me has been the lack of control in printing the final images. On the PC screen or on the tablet they look fine. However, once in the hands of the automated photo printing machine at Tesco or at the mercy of a specialised photo reprographics shop in Northampton they rarely end up as framed on the screen. I purposely resized all the following images at 10" × 8" in photoshop to make the job easier. However, the final images produced by the shop in Northampton have been trimmed and the overall composition compromised in a few cases!  Not a happy bunny! Ho hum!

Extension tubes macro madness

I now have my final pictures for the course! These are in the process of being processed into enormous 8" × 10" prints by some photographic laboratory in Northampton. All I need to do then is to stick these on foam board and write a description on how I managed to take them. All before Thursday 27th March!
In the meantime, I've been playing with a couple of extension tubes I recently bought via Amazon. These are lenseless tubes that screw onto the camera and shorten the focal length of any attached lens. The two tubes differ in width so you can vary by how much you shorten the focal length. With both attached plus my 14 - 42mm lens I can actually focus onto the inside of my daylight filter! These are not Panasonic lens tubes but they do have electronic connectors which comminicate successfully with the camera body allowing it to manage all the clever stuff like auto focus, metering etc. For micro four thirds readers here's the link. This is a far cheaper method of getting some macro close ups compared with buying a bespoke macro lens. These tubes also provide a greater range of focus than compared with the add on lenses. I'll do a comparison of extension tubes versus add on lenses so you can judge for yourselves!

Here are pictures using extension tubes. The wider angle shots use the narrower tube (10mm) , closer shots use the 16mm tube and the extreme close ups use both (26mm).

A slug slimed primrose .. this seems to have been flowering all winter!

The tubes do limit the depth of field considerably! F9 at 1/250. ISO 160. An image at f11 would probably be in full focus.

Same primrose, focus on far petals. F8 at 1/320. ISO 160.

Here is the add on macro lens for comparison.

This has an odd colour cast at the edges which can be a problem with add on lenses. I took this at f11 for greater depth of field. 

With an extension tube plus a narrow aperture (f22) ...

A rather slug eaten flower well passed its best!

Studio 2

Low Key

I really like low key lighting. This is partly because it allows the use of that wonderful word "Chiaroscuro". This word describes the effect produced by a strong contrast of dark and light created using very select lighting against a dark background. Here are a few of my attempts.

Originally had a blue cast through a poor choice of white balance

High key = lots of light with light backdrop

A bit on the blurred side ... but I like the overall effect

A bit reminiscent of school photographs

Photograms

Photograms

Photograms are very simple to make if you have a dark room. Apparently Man Ray came up with the idea. I always associate him with the sculpture made up of a steam iron with a nails sticking out. Quite odd, but then he was a surrealist.. Here is a link to some Man Ray Photograms plus other assorted artwork. Seems that Man Ray had a much better name for these, he called them Rayographs.
     Photograms are made by placing objects on top of photographic paper and then exposing the paper to light underneath an enlarger. This results in silhouettes of solid objects and ghosting of transparent / transluscent materials. The exposed picture is then developed / stopped and fixed by soaking / washing the photographic paper in three separate trays.

Here are two of my photograms using a "gorillapod", a transparent drinking cup and a five pound note. These were all exposed to between 3 and 5 seconds of light. Forgot to note the f number. Possibly 2.5?

This could be an interesting Rochache test! Could anyone who reads this (if there is anyone?) perhaps leave some comments on what you think you see?

Then by creating a negative version in Picasa (best free photo organiser / simple photo editor EVER!) a positive picture results ...

As I was quite enjoying myself I added a couple of my bolt on lenses and glasses. Fortunately for me I'm not paying for the use of the paper!

Which when inverted ...

Cloud storage of Photographs ... a personal view!

Cloud Storage

I've experimented with quite a few different photograph storage mediums in my time. I'm no expert, but I've been asked by a few people about it, so I've written a little guide/rant that some might be interested in. Follow this link to find out more!

White balance, naked "Bob", studio lighting and blueberries under forks

White balance

I have always been slightly mystified by "white balance", and I don't think I've ever moved the setting off the default one of AWB on any camera I've used. Camera manuals are singularly unhelpful as they simply show you how to set it, but not why! Now finally I understand! The idea of white balance is to adjust for the odd colour casts that might result from taking photographs in artificial lighting / shadows / Cloudy skies etc.

"White" objects will appear yellow under artificial light. This can be offset by using the White balance "incandescent" setting. This injects more blue into the image to offset the tungsten yellow. Similarly cloudy conditions can result in grey whites which can be adjusted for using the "cloudy" white balance setting.

As a demonstration here are three images of our studio naked torso "Bob". Bob is a grey silver colour, just about life size but somewhat lacking in the limbs and head department. These photographs were taken without a flash but with the aid of a "modelling" light.

Studio Lighting

This is called an "Infinity Cove" which is an all-white space with no corners, designed to give the impression that the background of an object extends to infinity. The white background allows for a range of coloured lighting using jells (coloured transparent plastic) and various other modifiers,

A lower level brightness "modelling" light is initially used to gauge where lighting would be most appropriate. This modelling light contains a booster flash which is synchronised with the camera via a hot shoe dongle (wireless /blue tooth?) . This provides a very bright light. The more expensive the lighting the faster it is to recharge.

There are five key elements to lighting to take in to consideration ...

• How even is the light and how does it affect white balance
• Intensity
• Contrast
• Direction
• Quality of light (e.g. diffuse, spot, soft box lighting)

Modifiers such as honeycomb light modifier. This can be used as a spotlight, but can be used to produce a brighter or more diffuse light by using different honeycomb thicknesses

Soft boxes as the name suggests produce a softer more flattering light

The beauty dish, a light source with a narrow 45° beam spread. When used close to the subject, the narrow beam spread allows a more selective area of coverage.

These, plus various other lights can be arranged in almost infinite variety. However, there are a few "classic" light settings.

Split lighting, Short lighting, Broad lighting, Butterfly lighting, Loop lighting, High key and Low key being just a few. 

"Short lighting" .. light from one direction. Photograph is taken towards the darker side.

"Broad lighting" . light from one direction. Photograph is taken towards the lighter side.

If you want to know more about lighting and have access to or room for a studio then have a look at this website..

Experimentally lighting blueberries, forks and wine

So ... lighting! As an experiment I tried setting up a little"studio" in our dining room. However resources are scarce! I have an angle poise light, room lights a few torches and a candle or two.

"Fork handles" at f5, 2 seconds exposure (using a tripod and remote shutter release) and ISO of 200. 28mm focal lengh

Any connection between this picture and a famous "Two Ronnies" sketch was altogether completely accidental! (Especially as I've never been a fan ... with perhaps the exception of this one sketch.)
The odd painting with the eyes had been stored behind this glass topped unit for some time. Quite serendipitous considering I was attempting to take a reflecting picture of arranged forks and blueberries to look like a pair of eyes!
I shot the above in a darkened room lit only by four candles reflecting off a white table top to the right. I did not twig the "fork handles" connection until much later. Here the white balance is set at a cool 2500K. I used a cheap wind up bluish LED light to illuminate the picture.

 Here is the "studio" with white A4 sheets used to blank off the book case to the left and the candles / white table top to the right. The wall at the back is a very pale green. This is a very poor picture! Must do better!

Shutter speed part 2. Dripping tap meets Lego swingers

By the way. I've added more images to this page

Varying shutter speed on a stationary camera

As a counterpoint to varying shutter speed while panning, the next exercise was to vary shutter speed on a stationary camera while capturing motion. One example I have seen is that of a dripping tap. A fast shutter should be able to capture individual water droplets, while a slower speed would turn a number of individual drops into a blurred stream. I didn't think that a dripping tap on its own seemed all that photogenic, so I added Lego figures swinging on cotton thread to provide a little more interest!

Note: No Lego figures were harmed during the filming of this sequence.

f16 at 1/4 of a second. ISO 160. Lots of blurry Lego with a blurred stream of droplets from the tap

f13 at 1/6th of a second. ISO 160. Slightly less blur. Blurred droplet stream still visible.

f11 at 1/10th of a second. ISO 160.

f8 at one 1/15th of a second.ISO 160. Some elongated droplets becoming visible.

f4.5 at 1/50th. ISO 160. Less motion blur on the figures.

f4.5 at 1/125 second. ISO 400. Motion blur reduced more. I had to up the ISO to get this faster shutter speed at f4.5

f6.3 at 1/1250th of a second. ISO 6400. No motion blur. Individual water droplets captured. Again, I had to up the ISO to get this faster shutter speed at f6.3
