THETA Tips

Basic Adjusting the brightness

THETA captures every direction so during the daytime while outdoors sunlight enters the lens and the image will have a mixture of areas with direct sunlight and back lighting.
This will cause no problems for front lighting in which light hits the main subject. However, the subject will look darker than it appears when there is back lighting.
In places surrounded by a dark environment, such as at night, people will also appear too bright. In such a case, be sure to use exposure compensation or the HDR rendering function that enable you to either adjust the brightness by compensating with exposure or increase the width of tone exposure.

Adjusting using exposure compensation when the main subject is dark or bright
EV±0

With the sun at the subject's back, in other words, back lighting. Shooting using automatic exposure will set the brightness of the photo based on the bright sky. This will cause the front side of a person in shadow to look darker than they appear.

EV+0.7

Adjust the brightness using the exposure compensation function. While checking the results of the compensation at live view, ensure that the brightness is such that the subject's facial expression is clearly visible and the background does not have significant blown out highlights before taking the shot.

Using HDR rendering for scenes with a big difference in light and darkness
Without compensation

Part of the image has blown out highlights and there is gradient loss.

HDR rendering

HDR rendering is a function that renders images that were shot continuously while changing the brightness automatically. It allows you to obtain images that have far less blown out highlights and blocked up shadows than images without compensation. It is essential to secure the camera in place such as using a tripod to prevent the camera from moving during the rendering process.
