Glad to see that you are working on 3 point lighting. However, given your limited space that would mean having three stands to get this sort of lighting in position, then there is your camera, so altogether quite a lot of apparatus. To be honest, I don’t feel that your table lamps will be all that practical for a complete lighting set-up. I assume you have a tripod or other support for your camera? I do quite a lot of filming of myself and I work alone so I can talk from experience. I use quite a powerful
single lamp but bounce the light off the ceiling/wall (basically behind or to one side of the camera) which gives a nice much softer overall lighting. Not exactly ‘creative’ lighting but adequate for most jobs. This might mean spending some money but there are several domestic standard lamps with powerful lamps already made to bounce the light upwards. However, workman’s site lamps, complete with tripod, are much cheaper. I realise that from a lady’s point of view, they are not super attractive but are practical rather than decorative – and cheaper. You will see from the price that I’m in UK but wherever you are in the world, similar items will be available. There are advantages in using artificial light rather than daylight. The light from lamps will be constant, whereas daylight will vary in quantity and quality depending upon time of day and the weather. As you intending to video yourself, another point crops up. I have no idea what camera you are intending to use, but if it is a model with a flip out screen that can be reversed to view yourself, this is rather small to compose and view when you are some distance away. Ideally some form of external monitor such as a TV with a bigger screen that you can connect to your camera to view the larger image and check many details. Care to tell me the camera you plan to use? You say that you have a wall that is ‘unattractive’ then why not try as
Farley Productions suggested, cover this wall with posters or similar that are
appropriate to what you are going to be talking about. As you are discovering, there is more to taking a simple video indoors – especially of yourself - than meets the eye. Attached is a photo that I hope will explain what I’m talking about. There are two images of workman’s sites lamps taken from the web that illustrate the sort of thing. Top left is a rough & ready shot of my room with a set-up using a typical amateur video camera. Note the small screen. The camera is attached to a small TV where you can see my image taking the still. The lamp (not the same as I’m talking about) is directed to the ceiling/wall behind the camera. It doesn’t matter what is there as you can see a Hi-Fi speaker and slightly patterned wallpaper
