10.1 The color temperature and the color deflection
If the object is heated, light is generated. Continuous heating increases the temperature of the object. At first the light generated from the object is red. The color is changed to orange, yellow and blue at last by increasing temperature. It this means the temperature of the object determines the color of the light. Then we call the color with the temperature of the object. This is called the "Color temperature".
For example, it is called 1500K, which the color from the object that temperature is 1500K. K(Kelvin) is a unit of temperature.
0K = -273.15C = -459.67F, K = C + 273.15 = (F + 459.67) / 1.8
These objects are called Black body radiator or Planckian radiator.
The temperature of the surface of the sun is about 6000K. This means the sunlight is 6000K as color temperature. But the color temperature of the sunlight that we can observe on the earth is about 5000-5500K because the blue ray is reduced during the air.
For another example, the light from the tungsten is about 2000-3000K.
However, the fluorescent light and mercury light are different type of light sources, which have different luminescence principle. For these light source, we also use the color temperature of the nearest black body radiator. Then there is a deflection from the real color of the black body radiator. This deflection is called "Color deflection" in this software.
A Black body radiation curve is only a curve in the color space. We need two dimensions to plot the point in the color space. One dimension is the "Color temperature" and another is the "Color deflection".
EXIF contains the information of the camera, setting for taking pictures, property of the image.
We can record some information, for example, shutter speed, F value, date and time, thumbnail image, colorspace and etc. to the output image file with the EXIF information.
SILKYPIX® Developer Studio is conformed to EXIF version 2.21.
One is the "Development parameter file" that the file-extension is a "spd". This file includes the development parameters, marks, rotation and etc. The others are called "Incidental files" in this software, which include marks, rotation and etc. for the JPEG/TIFF images. These file-extensions are "spj" or "spt".
These above files are created automatically and they are used to resume previous environment for the each scenes.
You can disable to create them by using the "Function setting" dialog. Refer to "9.3.5 Enable to save the development parameter and rotation information".
When the auto saving function is disabled, your modification is not saved automatically. In another word, your modification for each scene is kept until closing them by opening a new file or folder, "Close" command or exiting this software.
When you disable it to save the incidental file, the thumbnail files cannot be made too.
They are created automatically at the beginning of this software and deleted at the end of this software.
You can specify the folder to create these temporary files by using the "Function setting" dialog.
For example, the following folder is used; (XXXX: your user ID)
Windows 2000/XP: "Documents and Settings/XXXX/Local Settings/Application Data/ISL/SILKYPIX Developer Studio 2.0"
Mac OS X: "/Users/XXXX/Library/Preferences/SILKYPIX"
When you have some trouble on your system, our customer service may request you to operate some troubleshooting action.
Do not use the menu command [Help (H)] - [Trouble shooting] without our guidance, or unexpected action may happen.
As a default setting, SILKYPIX® Developer Studio creates the thumbnail files on the same folder as the image files.
DO NOT USE THIS COMMAND WITHOUT OUR GUIDANCE.
When you execute the command, this software will exit.
DO NOT USE THIS COMMAND WITHOUT OUR GUIDANCE.
You can convert the RAW data to a DNG data by using the tool provided by Adobe Systems Incorporated. Refer to the home page of Adobe Systems Incorporated for the more details.
10.5.1 Outline of DNG
The "RAW" type includes the RAW data itself that is recorded on the image sensor. And SILKYPIX® Developer Studio provides full performance for it.
"Linear RAW" type includes the partially developed image data that is already processed de-mosaic process. SILKYPIX® Developer Studio provides limited performance for it but can develop the image data that is not supported as original RAW data.
If you cannot develop the DNG, please retry with the "Linear RAW" type DNG.
(1) Any type of DNG from correspondence camera of SILKYPIX®
For "Linear RAW" type DNG, you cannot use some parameters for de-mosaic process, for example, NR, Development precision.
In this case, use the color reproduction method specified in the DNG.
In this case, you cannot use some parameters for de-mosaic process, for example, NR, Development precision, and it is used that color reproduce method specified in DNG.
