Architecture Photography Lecture 02 Shooting

"Equipment required for shooting"

tripod

A tripod is indispensable for properly taking architectural photographs. In the case of model photography or indoor photography, the shutter speed is slow, so if it is not fixed on a tripod, it tends to be out of focus. Also, a tripod is needed to take pictures while checking the angle, horizontal and vertical.

Release

If you release the shutter manually, it will cause blurring, so it is better to have a release. If not, you can use a self-timer instead. In the case of a self-timer, some cameras cannot be exposed for a long time, and it takes time to shoot.

Level

Recently, many cases are built into cameras. If not, display the liquid crystal in a grid and display the horizontal and vertical directions, and edit the details with a personal computer.

"Record format"

A digital camera usually performs image processing in the camera and records the image as a jpeg file. However, when taking architectural photos, I would recommend raw files.
A raw file is an uncorrected data file output by the light receiving sensor before the image is created. By importing this file into a personal computer, it is possible to manually perform the processing that is normally performed automatically in real time in a digital camera on the personal computer.
By using the raw file, it is possible to fine-tune the image processing while checking the output result. This operation is called "development".

"Characteristics of architectural photography"

1. The subject does not move

・ Because the shutter speed can be reduced, the aperture can be narrowed down. If you narrow down, the range of focus will expand.
・ I want to stop down now with the best resolution of f8 ~ f11. Many lenses become slightly sweeter when the aperture is stopped down.
・ Shooting is performed in the aperture priority mode, so that the aperture does not change without permission.
-Set ISO as low as possible. High sensitivity results in poor image quality.

2. The subject is large

Wide-angle lenses are often needed to capture the entire building. When there is no pulling, the camera often shoots and corrects, and in that case, a considerably wide-angle lens including a trimming allowance is required. It is safe if it is about 15mm.

3. Horizontal and vertical

Horizontal and vertical are the basics of architectural photography. Be careful when shooting. However, since there is a limit even if a level is used, digital correction is performed when there is a deviation.
The wider the picture becomes, the more unnatural the tilt becomes when the picture is not horizontal or vertical.
It may be intentionally furious, such as giving power. (In that case, it is less unnatural to make the angle of view a little narrower.)

4. Fine weather outdoors, cloudy indoors

Outdoor photography is best under blue skies.
However, indoor photography is basically better on cloudy days. When direct light enters the room, the contrast between shade and light becomes too strong. In addition, the outside is too bright, and the scenery from the window tends to be overexposed.
Cloudy weather allows you to shoot with less difference in brightness, and makes it easier to capture each detail.
When shooting in fine weather, carefully consider how light enters in the time zone and shoot as much as possible without the effects of direct sunlight.

5. Get proper exposure with Auto Bracket

Exposure is left to the camera's light meter, and two to three steps before and after using the auto bracket function. If it is a raw file, the software can correct the exposure to some extent, so even at 2EV pitch, the correct exposure will not be lost.

6. Depth and spread

If you want to emphasize the depth, make an angle like a one-point perspective view

1 point perspective

If you want to emphasize the spread, shake it slightly diagonally as in a two-point perspective view
