Before all things we must first calibrate its chain of work:
- Define the software that you will use to manage digital data.
- Set clear that we will use. (They do not all have the same absorption capacity, nor the same transparency to UV).
- Choose the printer and the settings thereof.
- Define the process for which we are going to stall.
and Photoshop Elements version, it will establish a working color space before starting to work an image. You can find online color profile Dan Burkholder. To adjust this you must:
- Launch Photoshop
- go to "Edit" menu choose
- "color"
- PC or do "ctrl + Shift + k"
The choice of parameter will be used to get a good reading of the gray scale will be used to create the correction curves. This is not the only setting that makes this possible. So you can work using other workspace, but it is important to always keep the same workspace to achieve the digital negative if the color changes and Contrast will not have the same effect and will not know to manage the same way by the printer.
Gimp does not have this control so it eliminates the risk of errors.
The first step of calibration is to determine the minimum exposure with a given transparent. why must we'll use a sheet of sensitized paper and cover with half a sheet of transparent. Then you take a piece of opaque cardboard that will allow us to make test strips.
then exposed the sheet each time discovering a new, blank presentation area. Finally, we develops, or body image is clarified by the process and we look for the exhibition area which allows us to obtain a maximum black as transparent. We will then set the exposure time base for this process with this slide.
