3D modeling techniques is most popular with beginners in which the artist begins with a low-resolution primitive and modifies the shape such as a box, sphere, and cylinder by extruding, scaling, or rotating faces and edges which are used to design the basic shape of the final model. This process uses a number of repetitive levels to get the final product, which can lead to a more efficient and controlled modeling process. Let’s take a look at a few of the most common used 3D modeling techniques.
4 Common Used 3D Modelling Techniques You Should Know
1. Digital Sculpting
The technology industry has integrated with various 3D modeling processes, that they call disruptive technologies. The artists use this advanced 3D modeling software programs to develop the models. Digital sculpting is a type of disruptive technology and has leveraged the 3D modeling process to a great extent. The modellers do not need to carry out the painstaking constraints of edge flow and topography. This allows them to design the 3D models, in a way similar to the sculpting digital clay process.
With digital sculpting, creature sculpting and character sculpting has reached to distinct levels. The modelers can carry out the process faster and with great efficiency. The artists work with meshes containing high resolution with millions of polygons.
2. Subdivision / Box Modeling
Box modeling is the most common polygonal 3D modeling techniques and that is used in combination with edge modeling techniques.
This is a polygonal modeling type where the artists make use of geometric shapes like cylinder, cube or sphere and then shapes it until the intended appearance is obtained. Box modelers carry out the process in different stages. First, they started with a low-resolution mesh after that they refine the model shape than they sub-divides the mesh, ensuring the hard edges are smoothened out and add the required detail in it. They repeat this process of refining and subdividing until polygonal detail is present in the mesh, which can convey the desired concept.
3. Image-Based Modeling
In this modeling, 3D objects are derived algorithmically from a set of 2D images that are static. This type of modeling is used where the modeler faces budgetary or time restrictions and is not able to develop realized entirely 3D images. This is one of the most common types of 3D modeling in the film production industry. Over the years, image-based modeling is frequently used in the entertainment industry.
4. Contour / Edge Modeling
This is another type of polygonal modeling technique, although it is different from box modeling. In the process, the modelers develop the model piece by piece, instead of refining a primitive shape. This is accomplished by placing the loops of polygons along the edges and filling the gaps that lie between them. This process is applied, as it is hard to complete certain mashes through box modelling. For instance, the human face cannot be achieved only through box modeling. You can collaborate with one of the reputed modeling organizations to get these models designed. The experts carry out 3D modeling process with skill and develop the desired models.

In big blockbuster films, we all know that the fantastical background looks underwhelming on set. With the use of green screen, filmmakers are creating worlds with an unbelievable sense of authenticity. Green screen is common and practical now with the rise of digital filmmaking.
Green Screen is a visual effects technique where two images or video are layered together. The green screen lets you drop in whatever background images you want behind the actors or foreground. It’s used in film production to relatively place the desired background behind the subject/actor. When a background isn’t available and impossible to create like a fictional, historical, futuristic, alien or even just hard-to-access location green screen comes to the rescue.
After the Shot, the Compositors take over:
The new background is composited (2 images or video streams are layered mutually) into the shot.
The chroma key singles out the decided color (green screen) and digitally removes it by rendering it transparent. Lets the other image to show through.
When used with more sophisticated 3D animation techniques, this process can add a new element (fire, rain, smoke, etc.) to complex moving shots.

Why is Green Screen used?
You can make use of any background color technically. A vibrant, almost neon green is the standard choice because it is a distinctly different color on the subject from anything (e.g. the clothes, hair, eyes, accessories).
The critical rule is no matching colors. The background has to be a different color from the main subject. Otherwise, if the actor is wearing a bright green tie in front of a green screen, then he will end up with a transparent layer down his chest where the tie is.
How to Set Up Green Screen in Shot
1. No Reflective Surfaces
Avoid any green and reflective surface from the shot. Don’t allow the actor to wear or hold anything green color or else the particular portion will become transparent once chroma-keyed. Any shiny objects will pick up the green from the screen and also be rendered transparent.
2. Allow Depth
For an entire shot of your actor, you will need to back up the camera to allow the full figure shot and a good separation between the green screen and the subject (At least 6 feet to avoid).
Depending on the lens, you will typically want 25-30 feet depth shot that don’t shoot off the edges of the background for a full-length.
3. Light and Softly
Light the green screen as smoothly as possible to give a smooth gradient and texture. The more even the lighting, the more comfortable and better it will be to manipulate the material.
Keep the green screen clean and smooth to maintain a consistent color range. If the screen is fabric, make sure there aren’t any lines. If coated, keep extra paint on hand to touch up any scratches.
4. Light Separately
The green background should be little separately from the subject to avoid:
The subject casting shadows and a green screen hue bouncing off the subject which creates problems when removing the background.
This is why you will need at least six feet of separation between subject and background.
5. Keep Camera Position Still
When green screen shots – Keep your camera in a static form. Lock the camera, so the subject doesn’t look like it’s bouncing or vibrating against the background when the camera moves slightly.
Your subject will look like it’s shrinking in relation to the background.
Use motion trackers and motion control for more sophisticated 3D shots, but it’s a lot more work for the VFX artists.
Use Chroma Key Software
Research and consider software based on the shots needed, the editing system and user experience. Your options for Chroma Key software will depend on the type of shot.

2. Options Bar: This bar shows several options for specific tools in the tool palette. When the user chooses a tool in the tool palette, the options bar showcases various preference for the particular tool.
3. Tools Palette: This palette is a collection of icons that are used for creating and editing images and page elements.
4. Document Window: It represents the current status of the file in which the user is working. Those windows can be docked and grouped as per the requirement of the designer.
5. Layer Panel: This panel helps the user to stack different things on the artboard on different layers to set them organized and make editing fast and easy.
Advantage & Disadvantage of Adobe Photoshop
Advantage:
Video editing is smooth.
The crop tool is quite useful.
Performance is highly improved.
Disadvantage:
No perpetual license.

Characteristics of Adobe Photoshop
1. Brushes
The upgraded brushes in the software offer the users to create clearer lines and smoother brush strokes. When the users work with the pencil, brush tools or mixers brush they get the benefits of controlling the brushes smoothing. You can enter the value from 0 to 100 for the smoothing of brushes.
2. Adjustment Layers
These layers are another form of non-destructive editing with Adobe Photoshop. With layers, the editing applies not on the actual layer, but it builds a new adjustment layer right above the pixel layer. This feature works in favour of the designer as and the designer can change the blend mode or apply filters, change the opacity or get rid of this layer anytime he feels so.
3. Camera Shake Reduction
This feature works excellent for editors and especially for photographers. When the person is working with some shaken or blurry images, it analyses the graph and restores the image sharpness.
4. Content-Aware Move
This feature works miracles for editors in this software. It lets the user select an object in the same layer image and move it away as per their choice in the same picture. Besides, Photoshop does its work amazingly by filling the gap made by moving the object.
5. Smart Object
These smart objects are non-destructive. The editor can edit and create multiple copies of the object which are interlinked with each other. It is a pixel independent and allows the user to scale it without getting blurry. The user can able to use various filters and edit them whenever required. Moreover, any normal layer can be easily converted to a smart object layer by right clicking on any layer.

The Refine Edge Tool in Adobe Photoshop is a powerful feature that lets you fine-tune selections, a task helpful when dealing with complex edges. This Refine Edge tool is available in the menu bar and the right-click context menu of the Photoshop. There are various controls in the refine edge tools like Adjust Edge and Edge Detection make creating natural selection task a lot easier rather than doing manually. In this Arena Sayajigunj Blog post we are going to teach you how to use Refine Edges Tool in Adobe Photoshop.
5 Step to Use of Refine Edge Tool in Adobe Photoshop
Step 1: Make a Selection
Start with creating a selection of your subject.
Make use of any selection tool which is available.
Here we will make use of quick selection tool.
The selection of the subject doesn’t have to be perfect but not to leave out the large part when making the selection.
Step 2: Open Refine Edge
Hold the Shift key then go to select in the menu bar and click on ‘Select and Mask’
The Refine Edge window will pop up.

Step 3: Select a View Mode
Depending on the colors of the photo you are using select a view mode of refine edge.
In this example the while background is perfect to see the selection and what we are doing.
Make use of different modes to learn which work best for selection you want to make.
Step 4: Adjust the Edges
The selection in this example is ok but far from perfect one. Still, grey areas in the hair and edges are rough. Adjusting the edges will set this.
Start with radius this is the setting you use the most when refining edges in Photoshop.
Increase the slider value to make the edges of the selection softer and natural.
For the most part, the radius defines what the result will look like.
Make use of 4 other sliders in the Refine Edge Window to get and most natural result:
1. Smooth Slider: The Smooth slider smooth out the edges. Keep it low because it takes away from selection. In this example: Here we use this slider to smoothen the edges of the hair.
2. Feather Slider: The Feather slider use to blend the selection more into its eventual background.
3. Contrast Slider: The Contrast slider adds more definition to edge. Using much will create harsh edges.
4. Shift Edge: Move the Shift Edge left or right to shrink or expand the selection.
Step 5: Output the Selection
Check decontaminates colors to remove color fringe before your output. It could be necessary when your subject is against a contrasting color background.
To finalise the selections select one of the output options. Usually, New Layer with Layer Mask is the best option. It allows editing the selection even further without losing the original quality of the photo.
There is no better way to select hair than using the Refine Edge tool in Adobe Photoshop.
Do practice a lot with the subject on different backgrounds. The Background effects how difficult making the selection will be.
Begin with uniform backgrounds and then move on to the colorful ones.
