Gesture is the correct answer.
1.a) The process of illuminating an object by putting the light source in front of the object is called front lighting. It is helpful in illuminating the object, especially when lighting conditions are poor. This is commonly done using a camera flash. But other light sources can also be used.
1. b)If the light source is directly in front of the subject, then the shadow tends to fall behind the subject. For this reason, front lighting often runs the risk of resulting in images that look flat, since the perception of depth is not available.
2. Strobe lighting is a flash of high power light that illuminates a subject during photography for a short fraction of time. Continuous light, as the name suggests, is a continuous stream of light that illuminates the subject for a longer period of time. With strobes, you can adjust the strength of the light, whereas continuous light, which tends to be quite bright, may cause human models to squint a lot. Moreover, since the strobe flash is very brief, it may reduce occurrence of movement-induced blurring.
3. Depending on the time of the day, the light falling on the subject in an outdoor setting tends to differ. This, in turn, has an effect on the brightness, contrast and shadows in the image. So the same subject, photographed at different times during the day will look different.
4. Continuous light, in contrast to strobe light, provides light in a continuous flow. Thus, the light present in the period before the shot and during the shot is the same. This is advantageous for the photographer as he can know in advance how the lighting of the image is going to be in the picture before actually shooting the picture. The disadvantage is that the brightness of the light for prolonged periods may cause human models to squint a lot.
5. A softbox is a translucent sheet that is placed on the top of a camera flash. This is used by photographers to diffuse the light falling on the subject, giving the subject a softer look, by blurring sharp or harsh edges.
6. Photographers use umbrellas while taking pictures in order to distribute the light in the ambience evenly. This effect causes the light , in turn, to fall on the subject uniformly, avoiding individual areas of the subject from shining too much.
7. When shooting indoors, the lighting in the ambience may not be uniform. Some areas may be too bright and shiny while others may be heavily shadowed. So to ensure that the subject gets a uniform amount of ample light, it is best to use artificial lighting.
8. The most challenging aspect of working with light in photography is knowing which lights to use at different situations and time. To overcome this challenge, the photographer has to make himself as familiar as possible with the different lighting sources and its effect and practice by experimenting on different subjects, with different lights and at different times of the day.
9. Yes, I have had my photograph taken in a studio. The experience was very interesting as I was able to get myself familiar with a lot of tools used in photography, like umbrellas, lights, softboxes, etc.The lighting helped enhance all the photographs. By adjusting the lighting each time, the photographer was able to achieve different effects on the photographs each time. The variance in the intensity of light as well as the position and direction of the light had an effect on the brightness, the shadows, highlights and hues in the image.
10. Since it tends to be dark and cloudy during a rainy day, it would be wise to keep an artificial light source or flash handy . Moreover, to avoid water getting into the photography equipment, a good rain cover for the lights, camera, etc. would be advisable. In spite of the shoot being difficult, it would help produce interesting images, as the camera catches the round spherical droplets of falling water, that look like vertical lines to the naked eye.
