Glass Ideas







I aim to include
  • Simplicity
  • Use of reflections
  • Experiment with pouring techniques as well as still liquids
  • Use of small but effective props (ie. Fruit, Ice etc.)

Workshop #7 - Large Format Camera Movements

Sinar with digital back



This is the single shot image. We used a fair bit of movement to get to the final result.
Front:
Shift - 2.5 right
lowered - 1.4
Swing - 0.1 left
Back:
Raised - 4
Shift - 1.2 right

From these movements we were able to get the focal plane to run from the bottom left of the black label box to the top left of the same box and then to the top left of the bisquit box. This allowed us to get the front of both boxes in focus. We also used rise to get the lines on the box parallel.


This is the 4 shot image using the same settings as above. I zoomed both images to 100% and compared them and I am yet to find any difference. Maybe it needs finer lines or more greyscale artwork until you can pick the difference clearly. From the images we saw in class there were definite advantages to the 4 shot method by capturing each pixel in 4 colours (two of which are green) but these images do not display any differences.

Medium Format - Hasselblad with tilt shift adaptor


This image is shot with all movements zeroed. As you can see there is a sharp zone running paralel to the angle of view and the entire page is not in focus.


With this image we used a scheimpflug to lay the focal plane over the page making the whole thing in focus. We used about 10 degrees of downward tilt and rotated the tilt shift adaptor 45 degrees to clockwise. You can see a vignette at the top of the image caused by using maximum tilt.


For this one we wanted his eyes and a line of text immediately opposite him to be in focus with everything else falling out of focus. To achieve this we needed the focal plane perpendicular to this area. Using maximum upward shift ie. 10 degrees, we were able to get an apparent shortening of depth of field we were after but now needed it to rotate in line with the page, or text as it were. By rotating the adapter 90 degrees clockwise the focal plane was now perpendicular to the eyes and the line of text.

SLR - 5d Mark II with canon tilt shift adaptor


For this image I was the subject. We shot with the tilt shift at max shift (13degrees) making the plane of focus as close to perpendicular to my eyes that we could which threw everything else out of focus.


For this one we aimed the focal plane on a diagonal line perpendicular to the face running from the left chin to the right eye. We rotated the tilt shift lens 45 degrees to the left and used max tilt of 13 degrees.
It was very apparent the limitations of this tilt shift compared to both the Hasselblad tilt shift and the movements available on the large format Sinar.
