As can be seen in the video, the color calibration is performed when image data are linear, which is very useful help of a transfer function display ( ScreenTransferFunction ). ;
Currently there is a tool which automatically cut the same, but with a few clicks. PixInsight Core is available in 1.5 from a few days ago with the name of ColorCalibration .
ColorCalibration The idea is based on using as reference two types of sub images (or previews). First, the white reference and second reference sky.
The reference targets can be for example the total light emitted by a galaxy, since we can safely say that most of all light sources emitting in the continuum (mainly stars). And then a sky background reference (background), here always assumed to be neutral.
In the picture outlined in the video blog is more difficult to find a white reference, because it is an object of a different nature. Ie not emit the photographed object in the continuous spectrum, but it does so in more specific wavelengths (emission lines). For this reason, the user interacts with the global statistics of the sky background, instead of using a white reference when calibrating the overall color of the image.
General Criteria: 1) Delivery of work on time 2) has control over published information and / or exposed 3) brings new and relevant information in the papers 4) Communicate ideas and information clearly 5) Attend classes with the material (files, documents, images) to move forward in the workshop
Laboratory Evaluation Criterion blog (individual): 1) publishes papers, concepts, terminology relevant entries 2) Post tutorials using digital paper from script.com 3) Post tutorials using code from Youtube ember 4) Publish the final work on the blog
Criteria Evaluation of audiovisual narrative and photoshop: 1) Respect the established format (720x480) a minimum of 40 seconds and a maximum of 3 minutes 2) video Transisón 3) audio Transisón 4) Place 3 photos photoshopped together with time sequence 4) titles at the beginning and end
720x480 Format 1) Free Transform 2) Color Correction 3) Brightness / Contrast 4) Grayscale 5) Lighting
individual's account must have a dramatic structure
When we ded language we refer to a series of signs properly encoded can address a specific field and communication. The image on a model that replaces reality by iconic elements (line, point, color) also presents a high degree of activity. Therefore media are half mechanical, technical, electronic record, play sound or visual messages that are used separately or together to represent and facilitate the acquisition, reproduce or modify certain behaviors In this way a foreground interpreted as the point of view of an observer, based on the expressiveness and emotion of the character. The darkening of the screen, represents the passage of time, the possibility of observing two parallel actions that occur in different scenarios.
MEASURES OF MESSAGE UNITS AUDIOVISUAL
3 units have been established audiovisual speech: 1 .- Sequence
2 - Scene 3 .- The plane
The sequence is the unit of audio visual story in which arises, develops and completes a dramatic situation. Can develop in one scenario, including one or more scenes, or can consist of various scenarios. It can also develop from beginning to end, or mixed with other sequences.
The scene: It develops itself has no effect full ramat
Plane: The smallest of significance of visual narrative, from which build scenes and sequences.
The shot is a term used to describe the capture of images by the camera. The shots are selected and combined through editing.
PLANE film properties include
3 factors: 1 .- Aspects
2 .- Full photographic plane 3 .- Location of the plane
The contrast between colors, including white and black type deeterminan ded image appearance. The audiovisual usually modify certain effects, to attract the interest of the expert
CONTRAST OF COLORS AND LIGHT
The crust refers to the difference between the most clear and the darkest plane. In film, the Contracting high ded ded area is bright white, black and rare dark gray. By contrast puededn cause espextador look toward brighter. Using a harsh light on the texture value, refuses to detail and the images are more flat, get soft light volume and definition. The use of space creates delicate high tones and bass playing mysterious images.
DEPTH OF FIELD AND FOCUS
called depth of field to the range of distance between the camera and the object within which objects can be photographed in sharp focus. short-focus lenses have a greater depth of field of focus that long.
THE FRAME
We define the plane, the fact of choosing a camera position makes a difference in the framing of the image and how Persiva the fact filmed. Can affect the image: -Size and shape "The angle and height " The way that the frame can move with relation to the staging
