Shutter Speed: The Moon

Playing with shutter speed and lead in all sorts of top tricks and unique effects.
This is one I have tried out myself and found more difficult that orignally thought.
After reading upon shutter speed I thought about trying to capture the moon and stars moving across the sky on a clear night.
I set up my DSLR upon my tripod to stop my hand from shaking and causing a blurred image.

I opened up the aperture to f8 as I thought this would be large enough to let suffient light into the lens; then I experimented with a setting called blub. This setting opens the camera's shutter speed with no limit. Thus, once clicked, the camera can be left for much longer periods of time: causing a longer exposure. photo one was left for 19 minutes and this is the effect the setting blub had when playing around with the trees and the moon, almost looks like day time:



However, in photo two the camera was left for 46 muinutes and the exposure was much brighter, slightly over exposing the moon behind the trees. The effect it has created in the photograph shows the moon almost as bright as the sun gleeming through the trees. To develop upon this, I would still experiment with the length of time when leaving the camera out, as there may be a balance between 19 and 46 minute periods in which the camera was left; the exposure could be lighter, however it may not reach the limit of being overexposed.

Another Quick Application: Balloons

Here is another link which would be a great stimulus to get the creativity juices flowing:

This shows that something simple and crisp as a balloon could create some interesting effects when applying depth of field and using aperture; when using a large aperture the background would blur and merge the colours into the background, however keeping the foreground crisp.
Another element would be to play with the movement of the balloons, panning the camera for a blurred motion effect. This could have colourful visual potential.

Applying Aperture and Shutter Speed: Milk

Using aperture and shutter speed could be used in different and effective ways. On the website for Digital SLR Photography magazine there is a activity which could create stop motion, it captures the milk hitting the dry surface and breaking away from the other droplets.

To create this on a digital SLR camera:
Aperture f10
Shutter Speed 1/200
ISO 100

Why not try the same technical applications to your camera, and see what effects are created with a fast shutter speed to capture the dropping of the milk. Play with the 6 creative aperture stops and see what different effects could be created through the correct fstops and how changing the aperture and shutter speed to photograph a more creative image. Play!

Check out the website and look under creative eye and see what interesting photographs you can create through using a fast shutter speed setting on your camera:

Law of Thirds

As I have been researching further into how to use aperture and shutter speed in photography, the Law of Thirds, is an element which could effect a photograph when playing with depth of field. 

For landscape images if you mentally divide your space up into 3 horizontial and 3 vertical lines: these are considered as the ideal focal points in trying to take a correct photograph. 
The upper and lower lines are ideal horizon point for landscapes, the lines help position how much sky is needed in the photograph. The law of thirds supports depth of field becuase it will give the photograph a correct composition supported linear perspective. 

Alternatively, law of thirds can also apply vertically linking to linear perspective; it can alter the composition of the photograph through weighting of the landscape. The photograph below supports this as I have used the law of thirds grid to apply a sense of shape and structure to the image.

Try This Out: Creating Depth

The website called: Photography Mad has some fantastic visual elements to his work, explaining how to try something new on the camera by applying the technical basics to an particular effect. The online tutorial which struck me as interesting and applies to shutter speed and aperture is the sense of depth. This ties in well with how to create a crisp photograph for certain elements such as landscape, portrait and close up photography.

This link takes you directly to the depth of field tutorial and has some interesting points about using foreground framing and using angles in the photograph. For example, crouching close to the ground add an exaggerated perspective when shooting landscapes and adding a greater amount of depth to the image.

Here is my own version of creating perspective and depth of field. This photograph was taken using a very small aperture at f20 and a shutter speed of 1/13. The aim of the photograph was to exaggerate perspective, but to also show that even on a dull, cloudy day an interesting photograph can be taken, when selecting the right aperture against shutter speed; this creates an unusual stance if exaggerating the depth.

Worth a look at the website and it has useful visual tips for you to try.

Shutter Speed: example of exposure.

Here are some examples of exposure and the difficulties that can arise when playing with technical issues of aperture and shutter speed. The first image is where a spot light has been used onto a piece of work to create shadowing; I have applied the idea of shutter speed and keeping the sensor open for varying amount of times.

Photo One:
This has worked as a whole, however after leaving the shutter speed open for 4 seconds (PUT IN NUMBER!!) the object has become slightly over exposed in the top left hand corner of the photo. This might be due to a number of reasons: that the spot light was too close to the top of the subject, causing an overload of light into one area; the shutter speed was open too long and therefore too much light was let into the sensor; therefore the aperture could be adjusted to reduce the opening of the lens thus balancing out the light exposure.



Photo Two:

This is an example of the opposite to photo one. Here the camera was changed to a faster shutter speed where the camera was only exposing the sensor to light for 2 seconds (ADD IN NUMBER). There is a huge difference in lighting. The same source of light was being used, the camera has let in less light, therefore the photograph is much darker and dull. To develop on this, I could have changed the aperture so the lens was bigger and f stop smaller, balancing out the smaller shutter speed with a larger aperture. 

 

F Stops and Aperture

http://www.picturecorrect.com/tips/how-to-use-aperture-and-f-stops-in-photography/

Here is a great bank of information, tutorials and tips which I have found useful when learning about aperture and shutter speed; getting to grips with the concept can be difficult to start with, but this website breaks down the stages into manageable chunks so the idea is simple to understand. 

The section about what each of the numbers mean and how they can be used is helpful and can support any photography work that is being developed. Once you have the basics then you can  build upon these techniques to begin to make something creative and unique. Apply the techniques is the fun part where you can free motion, capture light and blur images into one, just by using aperture and shutter speed.

There differences between large and small apertures and they both can give very different effects when they are used in digital photograpghy.
Large Apertures are useful for portrait photography, capturing the face of the person or subject and blurring the background to stop detraction from the subject in the foreground.
Small Apertures are great for landscapes to keep a vast amount of space in focused which creates a greater depth of field.
