I'd rather spend my time reviewing settings for studio lighting to make a nice image of a single object, especially when you have to manage glare on chrome ob-jects! Recognizing this loss of time, I threw myself into the design of this studio pak shot. A pak shot is a high quality photo of a product on a solid background in most cases, used to present said product in a product catalog.
This is a real illustration for a pak shot (+ software box studio settings). This is exactly what I wanted to create in Blender ...
Pak Shot Studio for Blender is a virtual solution that simulates the effects of shooting an object: light scattering, reflections of the flash on the reflective material, adjustment of the focal blur ...
Although the process of image production hasbeen greatly simplified, it is necessary to have some knowledge in 3D and the Blender environment to better understand Pak Shot Studio. Knowledge about studio photography is a plus.
You will find in this file: 3 lamp types with each one having at least one Target to aid targeting, adjustment for distance and energy and adjust color of the light in the 3D view.
A "Flash" like a "Software Box" which includes an adjustable light box (square or round).
It's good for software illumination without specular effect and maximum diffusion shade.
It alos creates a square or a round reflection on ob-ject.
A "Flash" studio with adjustment outreach di-rectly in the 3D view.
It's a good way for lighting effects mixed with spec-ular shading and rough shading.
A neon "Flash" studio
For software lighting and specular both, perfect for a garage effect on a car body.
It creates a neon tube reflection and a relatively stronglinear specular reflection on object .A customizable shooting table.
A Camera with a target, an Auto-focus (coupled to Target or manual) and a zoom ring.
A node for development (rendering) that allows the management of focal blur based on the settings of the camera. It alos adds a slight defect to the lens to accentuate realistic rendering.
First, let's see how I structured my file.
We have to take a unit for 3D / perspective = 1 unit of local measurement.
We will use metric system, so a unit is 1 meter.
In a case where the scale of your object is different from the studio, scale the import object in the studio.
Set the shadow samples of "flash", do not abuse this setting (make it too high) because of rendering time! A sample from 4 to 8 is a good average.
Consider the sample settings of the Ambient Occlusion, especially recommendations for the "flash". Values from 4 to 8 are good averages.
Let's start by opening the file. First, chek that the settings are all enabled for replication ([i] User Preferences>
Methods Edit> Duplicate With Object) to avoid problems when duplicating a standard "flash" (Shift + D).
The Studio consists of three areas of worque and information on where we are. To select a workspace simply activate the menú with the prefix [SR:].
1. Composing the Scene
Let's enter the scene, choosing the scene menú and select scene 1. This space is used for positioning objects and settings and flash in the studio.
Activate the layers 1, 16 and 18, show suzanne, table and flash software box.
What makes up the layers in the Studio?
1. Suzanne Material Tester
2. Sphere Material Tester
3. Glass Material Tester
11. Hyperfocal Bak-ing Sphere. For use in the workspace: 3 hyperfocal Bake
16. Shooting Table:
frame = Table / Ob-ject Table
Objects = Frame
Camera / Camera
CAM / Z Subject meter
18. Flash Software Box:
frame = Software Box /
Object Software Box /
Lamp Software Box
19. Direct Flash:
Visible Objects =
Flash Frame Direct /
Direct Flash Object
/ Lamp Direct Flash
20. Neon Flash: Vis-ible Objects =
Frame Neon Flash / Flash Object + Map Dupli Spec Neon
/ Neon Flash Lamp (no spec) / Neon Flash Lamp Spec (no diffuse)
How to duplicate a group flash?
Method 1: Simple Duplication
The flash will duplicate independent settings of the du-plicated flash.
Select any object that makes up the "flash" to dupli-cate.
Make Shift + G> In Same Group or Object In Same Group.
Make SHIFT + D: All the information from the
"flash" is duplicated.
Note: I strongly recommend starting the selection process from the frame.
Method 2: Multiple Copying
A single "flash" (parent) controls a set of "flash"
(children) of the same type.
Create any object on any layer, an Empty is the sim-plest.
In the panel: Window Buttons> Object (F7)> Anim
Settings and activate DupliGroup.
In [GR:], type GR "The Name Of The Flash. example:
GR: GR Software Box
The DupliGroup appears behind the object that duplicates it.
Create a plane that you subdivide (be reasonable in the subdivisión, avoid large values).
Parents who used to be DupliGroup this plane.
Keep only the plane selection.
In the panel: Windows Buttons> Ob-ject (F7)> Anim Settings and activate or dupliverts DupliFaces.
Your flash original is duplicated for as many vértices or faces that make up the plane. The settings of these clones will be totally dependent on "flash" original.
2 Light Room : Configuration space of the initial rendering and rendering composite.
3 Hyperfocal Bake : Make a record 360 ° x 360 ° of your scene and save the resulting image into a background image HDRI.
This process will be a little long depending on the size of the rendering.
I hope you will enjoy using this studio. I still have to adapt it to Yafaray and Luxrender and make a versión for Blender 2.5x (too many bugs for the moment - even with the Alpha 2).
