bykks studio lighting
With bykks studio you can choose from photographic or circular backdrops, arrange countless light combinations by choosing from 7 different lights: large left, right and center soft boxes, two different ceiling light banks, large lightwall and one ringlight.
bykks studio comes preformatted as a maya 2012 scene file.
In the Channel Box/Layer Editor you will find two backdrop layers to choose from; a simple studio backdrop and a 360 degrees one reaching from floor to ceiling. Enable or disable them by turning on/off the according layers named correspondingly to the backdrop they represent
In the Channel Box/Layer Editor you will find various lights, set up for your immediate use. Enable or disable them by turning on/off the according layers named correspondingly to the lights they represent.
Select the light in the attribute editor and switch to the light settings using the two arrows in the upper right.
The most important setting you will alter from time to time depending on your use of the light will be the ‘Manual Peak Intensity Cd’. Here you can set the light’s intensity by entering a candela value.
I don’t know what works for you, but I’m not really into setting up candelas and rather like to use lux values with which I’m more familiar. In order to find the appropriate value for this field I always follow these simple steps:
measure the distance between your light’s position in the scene and the object you would like to illuminate by using the ‘create/measure tools/distance tool’ from the menu bar.
Now go for example to this site which i find very useful (thank you RapidTables.com!) and enter the desired lux value and the measured distance from your light in the correct fields, click on ‘calculate’ and you will be presented with the appropriate candela number.
enter the candela value in the light settings in maya and you are good to go.
These instructions make sure you will get the desired light intensity spot on so to say. But before you can do the calculation from candela to lux you will have to choose your desired lux intensity. Guidelines for various values in difference conditions can be found for example here (thank you lux-meter.de!) or here (thank you wikipedia!). Generally 700 till 1.500 lux should be a good choice to work with.
Out of the box all lights are set up to deliver around 700 lux. If you choose to use several lights at once please consider changing the shutter speed/iso/aperture (F Number) values of the photographic camera.
Select the light in the attribute editor and switch to the light settings like you did before to change the light’s intensity. Here the color box shows black and right to it you see a small black arrow. Click on the arrow and you will switch to the lights’s cie attributes. Set the desired temperature by entering a value since this is the most accurate way. By default the values are set to produce a slightly warm light at 5.600 Kelvin. Other useful settings are 6.500 K for a neutral and 7.500 K for a cold tone. Try to experiment with theses setting and give the lights different temperatures for amazing results.
Still you can change the lights color by breaking the cie connection and entering manually a color which then will act like you added a gel to the light. This might be useful since the cie temperature settings just cover a small region of colors (from 4000 to 25000 kelvin) – which is okay if you plan to stay in the neutral area.
To use the lights in all it’s glory the cameras need to set up as photographic cameras. With a photographic camera you can -just like with a real slr camera- adjust the settings to compensate for an overly lit scene for example. The adjustments you can make come close to a real camera’s settings but obviously lack the depth of field which will have to be set elsewhere in maya and the noise you’d get with high iso films.
You may want to change the Film Iso, the Camera Shutter and the F Number settings in order to properly depict your scene.
To make good use with the possibilities you’ll get with this lens shader I would suggest to read at least an introduction into photography and the basics which will help setting up the camera. An example can be found here.
To instantly start, the perspective view and the photographic camera are connected to the same settings. So if you adjust the values to work with your light set up both views will produce proper results immediately. If you add new cameras please do not forget to connect them to this lens shader.
bykks studio lighting is available preformatted for maya 2012 and currently in beta phase.
