Camera mapping is a clever technique that allows you to take a still image and convert it into 3d geometry for use in an animation. This powerful technique is used extensively by visual effects studios for feature films, commercials and television shows
During the tutorial you will learn:
* What camera mapping is used for
* How to easily project any image onto a 3d object
* How to match the perspective of a photo
* How to overcome a common camera mapping problem
* How to use the very useful ‘sticky’ texture function
Every color pixel in a digital image is created through some combination of the three primary colors: red, green, and blue. Each primary color is often referred to as a “color channel” and can have any range of intensity values specified by its bit depth. The bit depth for each primary color is termed the “bits per channel.” The “bits per pixel” (bpp) refers to the sum of the bits in all three color channels and represents the total colors available at each pixel
In this video i tried to explain the color depth fundamentals of any image.i used some basic examples for explaining all type of bit depth
(8 bit , 16 bit, 32 bit )
Hopefully this tutorial helps you to understand the color depth(8,16,32 bit)
Adobe Photoshop also offers a number of selection tools: Quick Mask, Rectangular marquee, Elliptical marquee, Lasso, Polygonal Lasso, Magnetic Lasso, Magic Wand.After these tools there are some advance selection tools which we use to make crucial selection on an image.Masking or Selection of an image is the most important part for compositing.Through this tutorial i want to share some basic concepts behind selection or masking.Hopefully we’ll get to know how we can use a better selection process for our compositing.
In the Advanced tab of the Composition Settings dialog box Composition – Composition Settings, choose Preserve Resolution When Nested or Preserve Frame Rate When Nested Or In Render Queue for a composition to retain its own resolution or frame rate, and not inherit those settings from the containing composition. For example, if you deliberately used a low frame rate in a composition to create a jerky, hand-animated result, you should preserve the frame rate for that composition when it is nested. Similarly, the results of Rotoscoping may look wrong when converted to a different frame rate or resolution. Use this setting instead of the Posterize Time effect, which is less efficient.
Many Photoshop users learn to use the Levels dialog and then never progress to learning how to use the Curves. Let me give you several reasons why learning to use the Curves will make you more of an expert with Adobe Photoshop.
In digital photography editing, both the Levels and the Curves are used for one of the single most important editing tasks: image tone control. Whenever you have a photograph that has less than perfect contrast, i.e. the contrast is either too low or, conversely, too high, you need to use some form of tone control. Both the Levels and the Curves allow you to alter the black and white end points of the tonal range in the image. Adjusting the end points allows you to change the global or overall contrast of a photograph; the method and affect is the same whichever of the two commands you choose to use.
Both commands also allow you to change the appearance of the intermediate–or grey–tones in-between the black and white end points. However, the important difference between the two commands is that a Levels adjustment proportionally changes all of the tones in the tonal range; whereas the Curves allow you to choose which portion of the tone scale you wish to adjust. The Levels is a linear adjustment but the Curves are a geometric adjustment (in fact, this difference is in the names: levels and linear, curves and geometric). This is a massive difference, and using Curves rather than Levels will elevate your editing skill to a professional level.
