What Is Light

Over the centuries, our view of light has changed dramatically. The first real theories about light came from the ancient Greeks. Many of these theories sought to describe light as a ray -- a straight line moving from one point to another. Pythagoras, best known for the theorem of the right-angled triangle, proposed that vision resulted from light rays emerging from a person's eye and striking an object Light is part of the electromagnetic spectrum, which ranges from radio waves to gamma rays. Electromagnetic radiation waves, as their names suggest are fluctuations of electric and magnetic fields, which can transport energy from one location to another. Visible light is not inherently different from the other parts of the electromagnetic spectrum with the exception that the human eye can detect visible waves. Electromagnetic radiation can also be described in terms of a stream of photons which are mass less particles each travelling with wavelike properties at the speed of light. A photon is the smallest quantity (quantum) of energy which can be transported and it was the realization that light travelled in discrete quanta that was the origins of Quantum Theory. It’s a kind of energy called “electromagnetic (EM) radiation” (but this kind of radiation is not harmful, except for occasional sunburn). There are other kinds of EM radiation too (radio waves, microwaves, x-rays, etc.), but light is the part we can see, the part makes the rainbow.

Selection Tools in Photoshop

Lasso Tool
The Lasso Tool is 100% freeform. Simply grab it and start drawing with your mouse or track pad to make a selection. Obviously, the result is going to be rudimentary at best and even tends to be quite sloppy.

Polygonal Lasso Tool
The Polygonal Lasso Tool allows you to click from point to point to gradually build a selection. Selections made with this tool are purely comprised of straight edges. If you don’t mind some tedious clicking, you can pull off a primitive curve, but for the most part you’ll definitely want to stick to hard edges.

Magnetic Lasso Tool
The Magnetic Lasso Tool is a lot like a cross between the Polygonal Lasso Tool and the Magic Wand Tool. It allows you to build your selection incrementally, but in a fairly automatic fashion. Simply move your mouse along an edge and the MLT will give its best guess for outlining that edge. You can let the tool build your points automatically or manually click if there’s a specific point that you think needs to be dropped. 

MAAC Preet Vihar Alumni Meet: 2014-15

Maac Preet Vihar celebrates 11^th year of Success. This early year has brought a lot for all of us. Maac Preet vihar has won best placement award in across pan India. This means we have provided maximum jobs to our students and placed them well in one of the leading studios of Animation industry. We are proud to call for our students that “Students of yesterday, Professional’s of today. We are very excited to call an Alumni Meet in our respective centre which was lead by our Senior Instructor’s and Centre Administrators.

The Alumni meet was focused to develop the confidence in existing students and help them also to raise the flag ship of our institute to even a further level. We call off our Alumni’s who were once students and used to get teaching from the same place, who are now working in eminent companies.

Our motive is also to felicitate their hard works and to make new bees to acknowledge the hard work and studies they made once to fetch the desired jobs. We believe that getting the desired jobs after the successful completion of the course is a real excitement. The Alumni’s were called to share their industry experience and provide cutting edge and best solutions and career perspective to our existing students. This way we ensure apart from regular teaching we do put our stress on activities of knowledge sessions and seminars to help students in establishing careers.

Maac Preet Vihar is always in highlights when it comes to participation in extracurricular activities and seminars and workshops where we also call industry leaders and senior production artist to provide hands on and career related training to the students.

The Alumni meet is a successful event of our centre and we wish to continue for long and long to provide continuous updates and knowledge emergence program to maintain our league to remain the top level 3D and VFX industry educators.

3D Wall Art

3D wall art painting have been around since the sixteenth century. The magic of 3D is created by painting a 2d picture and viewing it from a specific angle to capture the right perspective. MAAC Preet Vihar is going to feature some of their latest and most awe-inspiring pictures.

What Is a Mask in Photoshop?

The term “mask” isn’t immediately understandable to someone outside the realm of graphic design. At its simplest definition a mask is a way to apply something to a very specific portion of an image.There is two primary types of masks: clipping masks and layer masks. These two tools are closely related in concept, but very different in application.

Layer Masks: A layer mask is something that you apply to a given layer to control the transparency of that layer. Where layer opacity controls the transparency of the entire layer at once, a mask gives you more precise controls over very specific areas. If you want the entire layer to be at 30%, you would lower the opacity, if you want just the left side of a layer to be at 30%, you would use a mask. On this invisible canvas, you can paint white, black or any level of gray in-between. The color that you paint tells Photoshop how opaque to make the pixels at that point. White means 100% opacity and black means 0% opacity. There are ways to see it that we’ll check out later but just know that as a general rule, applying a mask to a layer won’t cause any immediate visual differences unless you have an active selection at the time.

Clipping Masks: Clipping masks are very similar to layer masks only they use one layer to determine the transparency of another. In this scenario, you stack two layers on top of each other with the bottom being the determining factor of the transparency of the top. Instead of using black and white values though, clipping masks simply borrow transparency from the layers used to make them, namely the bottom layer. If the bottom layer has some areas that are opaque and some areas that are transparent, a clipping mask will apply these values to the top layer.

Personality Development Classes

It has been noticed that even after getting good education people find themselves lacking somewhere when it comes to their own personality. They feel difficulties in facing public. Now days every organization wants to have multi talented man power, so we need to develop ourselves at all the level. Most of us, in some time of the life, have to speak before a group of people. Some people take this public speaking as an opportunity whereas others are likely to be anxious just with the thought of addressing a room full of audience. They would leave no stone unturned to escape from the situation. This is quite true that people who are scared of public speaking lack confidence but they can surely build it up. Like others, they can also speak well, capture the audience and set themselves apart. Personality development training helps you to overcome all these difficulties and speak with confidence before huge audience.

Light

Light is a very complex phenomenon (A phenomenon greek: from the Greek word ‘phenomenon’, from the verb ‘phanein’, to show, shine, appear, to be manifest (or manifest itself), plural Phenomena, is any observable occurrence. Phenomena are often, but not always, understood as ‘appearances’ or experiences’.), But in many situations its behavior can be understood with a simple model based on rays and wave fronts. A ray is a thin beam of light that travels in a straight line. A wave front is the line (not necessarily straight) or surface connecting all the light that left a source at the same time. For a source like the Sun, rays radiate out in all directions; the wave fronts are spheres centered on the Sun. If the source is a long way away, the wave fronts can be treated as parallel lines.

Light as said has seven colors.

Violet
Indigo
Blue
Green
Yellow
Orange
Red

Violet has the least wavelength. Red has the highest wavelength.
