Manual sketching broadly falls under two categories:
1. Pencil sketching
2. Rotor Ink sketching
3. Coloring methods
Pencil sketching
This type of sketching is made using pencils of differing lead thickness. I would recommend novices start out with this type of sketching as mistakes can be erased.
Pros:
- Easy to edit
- Show shading variations with less effort
- Useful for creating outline (concept) sketches and creating drafts
- Widely available
Cons:
- Easy to smudge pictures
- Fades over time
- Harder to preserve
- Clarity of the drawing heavily dependent on the type of paper used
Rotor Ink Sketching
This type of sketching is done using special pens called rotor ink pens. The main feature of the pen is the differing thicknesses of the nibs available for the pen. I would recommend that you get some practice sketching with pencils before investing in the rotor ink pen.
Pros:
- Excellent sketch clarity
- Easy to preserve
- Different ink colors available
- Delicate detailing possible without smudging
Cons:
- Expensive to buy equipment
- Fragile nibs
- Not available everywhere
- Nibs need lot of maintenance - The ink dries and clogs up the tip of the nib. This can be extremely difficult to clean. So make sure you use the nibs frequently - or clean the nibs after use immediately.
- Difficult to edit
Coloring methods
There are different types of coloring methods. Some of the methods I have used include dry crayons, charcoal sticks, color pencils, crayons, pastels, watercolors and oils, and, sketch pens.
These are generally used to create detailing and shading effects to drawings created using pencils or rotor ink. This is an extremely useful for color coding sketches such as landscaping, highlighting sections and differentiating types of walls etc.
