Why blender to a photographer?

Are there photo studio emulators? My friend once asked such a question, studying the prices for the rental of illuminators and recalling the first experiments with table lamps and Whatman sheets. Good studio lighting is expensive, it requires a darkened room and special backgrounds. In the virtual world, experiments with light are not limited by anything, and the result can be repeated in reality with a ready-made circuit. We found some applications. Paid and even online . But his hands itched to do something of their own. Allocated a couple of days off for a beneficial work and modeled a virtual studio with lighting presets and a “model” of Suzanne - a mascot of the free 3D blender editor.





First you need the editor itself. He is free. Choose on the siteyour system, version, bit depth and install. After the first launch, you will open an empty scene with a cube, a camera and a light bulb. The first thing you will encounter is the unusual behavior of the program: objects cannot be selected with a left click, instead some sort of striped circle moves. This is a historical feature of the PCM object allocation program. You can immediately switch to the more familiar selection with the left button. Press Ctrl Alt U , the Input tab , look for the Select with switch on the left and change it to left . Save the settings with the button below.
Ok, now you can select the cube and move it behind the arrows of the axes.

Very briefly about the transformations. In a blender, most actions are tied to shortcuts. At first it scares, and after adaptation, you are surprised at the speed and convenience of this way of working. If you want to do three-dimensional in a blender, then write shortcuts from the earliest stages of training. Useful. The principle of manipulation of selected objects: a single press of the buttons G (grab), R (rotate), S (scale) activates the movement, rotation and scaling. A single click and then moving the mouse is enough to hold the mouse button is not necessary. Left-clicking is equivalent to enter . Click when you move or rotate the object sufficiently, the manipulation will apply to the object. If you press G thenZ (or X , Y ) then the movement along one axis will turn on. If you accidentally enter one of the modes, press Esc .


Now open the file with the studio. And we’ll see such a rage: Probably your look will be slightly different in colors, but a fashionable skin is included in the package, the link is below. The large field in the upper half of the screen is the node editor. It displays the material settings of the selected object. The blender does not have the usual material editor as in the “max”, the material is edited in the object contest. Select objects and the window will show the nodes of their materials. The 3D window of the lower left view is a view of the scene from above. The adjacent window is a perspective view. The small window in the upper right is the view from the camera. The options on the right are the render settings and properties of the object. You will learn the meaning of them as you learn, the task of this article is to give a purely overview of the editor’s ability to beginners who first opened a blender.

The scene prepared several lighting schemes.

Caramel light from two opposite in tone softboxes. Previously, there was a chip very popular among three-dimensional artists, now it’s not really.


Analog ring flash.


Light imitating the shade from the blinds.


Sunset sun.


Lighting in a dark photo room.


Switching between schemes for setting light is implemented through layers. Layers become visible if you select them in the selector under each projection window. Please note that the monkey layer is in the upper left slot, and the lighting layers are in the right side. To select two layers, hold Shift . You can try mixing the lighting layers. Experiment :)

I forgot to say the most important thing. Rendering is started by pressing the F12 button , after the scene is miscalculated, you can save the result as a picture, place the cursor on the result and press F3 .

For ease of use, there is a memo .

What goals would you like to achieve?

- A sandbox in which light sources and indirect reflections are simulated quite correctly.
- Visually show how the magnitude of the flare and the sharpness of the shadows depend on the size of the light source, how reflections, shadows behave.
- Attract attention to the blender editor. If at least one person gets carried away, I will be very happy.

If the topic turns out to be in demand, I plan to make more realistic light sources, convenient manipulators (so as not to climb into the material settings), a model of a living person, a more nimble and physically accurate rendering engine with real lamp characteristics.
