Interior Architecture

For this workshop, issues of Perspective control, mixed light sources, and subsequent colour correction were highlighted. With the problem of color correction/white balance, there are a number of ways that the CWB can be achieved. They being setting the color temp to that of the key light. The second of which is the use of an Expo disc. The third is to use a colour temperature meter and to subsequently dial in the read out into your camera's preset. There is also the use of a grey card to set a custom white balance within the camera. Lastly but not least is the adjustment of the raw file within post shoot software such as lightroom. This is achieved by having a grey card in a preceding shot, and sampling the WB for the real shot.

The width of the lens used can create problems like barrel distortion as the lens tends towards its widest ability. This presents itself almost as reverse convergent line lines, whereby the the interior lines of a building or structure can appear to have outwardly divergent lines.

Again my version of Photoshop did not have lens correction filter so I was left to modify the output using photoshop's CS1's less than efficient perspective and control

Foreground/back ground compositional considerations

Floor and ceiling with element /creative light interest. Has been post produced to bring up the whole image to show relevant details of the structure as well as the feature element.

Ideally all of the corrections in these images should have been achieved in camera with the correct use of a PC lens, and on location custom white balance adjustment. However the technology available to me albeit out-dated was sufficient to make necessary adjustments to these interior images.

Use of available light/flouro... compositional integrity

Exterior Architecture

For this workshop we were assigned a number of images to take in respect to some of the key elements of exterior architecture.

These elements are those of Perspective correction for converging lines, lens correction for distortion, colour correct (custom white balance). Also compositional considerations are equally important with creative uses of leading lines, repetition, rule of thirds, depth of field, abstract. symmetry etc etc..

The biggest issue that I encountered wit this work shop was the relatively long lens that I was using. Even on full frame the 22-70 still was not wide enough to capture the (full) building at the desired angle. I needed to move back too far or else when it came time to correcting the perspective, too much of the image was cropped and lost, especially the foreground. The other limitation I discovered was using a too early version of Photoshop (CS1). It doesn't not have any correction for  lens distortion and its perspective adjustment was quite crude, leaving me to having to manually readjust the scale of each corrected image.

Converge correct...This image first presented itself as not needing perspective correction, but upon closer inspection revealed the that actual vertical lines needed attention. which was carried out. This problem is evident in a lot of the buildings that I shot, as contemporary architecture seems the favour non vertical outer lines

From this workshop it was highlighted to me the importance and difference color and perspective correction does make to the final image. Needing to shoot whole buildings at dusk in winter is extremely problematic as its tricky to be at one with the structure when all you can think about is leaving it and going home.
