Making of "Ephemeral dreams"

To create this work, I mixed a 3D rendered labyrinth with some photos. The final photo is composed by these three kinds of images, created in this order:

Hands: I used a Canon 17-40L lens at 17mm, f/20 to get a lot of dof and flash on the right with a small softbox.

 Sand falling:

I needed to get some photos of sand falling and merge them together to create the parts where the labyrinth was melting. My photoshop skills are very limited so I had to get a good perspective and shoot at 17mm too in order to facilitate the edition. I did some tries using a shutter speed of 1/30, also f/20 and natural light to get a kind of “silk effect”, but when I joined the captures with the 3D labyrinth, the result looked like plastic. I repeated the sand captures using flash to get the opposite appearance (freeze the motion), and I stuck with that setup for the rest of the photos I needed (just 3 or 4).

Labyrinth: Modeled with 3D Max 2014 with iray. First I created in Photoshop a 2D image in black and white with the labyrinth I wanted, until I got this:

I added some layers and used the gradient tool to darken the corners so that the labyrinth appeared that was melting when applying later the “displace” modifier in 3D Max (depending on the shade of gray, the height of each wall will differ).

Then in 3D Max, applying the modifier “displace” I used the displace map created to get the 3D appearance. With the modifiers melt, noise, wave and bend I added some imperfections, and also edited the mesh of the labyrinth to melt much drastically the middle part and the sides. Result:

laberint_high_low_mid_fused

Each part was processed with Lightroom to add some dramatism by using clarity and blacks, and changing the temperature of the captures, and also desaturating to have a similar appearance in all of them and facilitate the Photoshop part.

Light Painting Wireframing tool

The idea:

Create a tool that projects a laser net to combine with the Light Painting photography technique, so that when projecting this net over a scene, it “seems” to be a wireframing view of a 3D modeled scene.

Solution:

Using only one laser pointer, create a set of horizontal and vertical lines that combined with the photo long exposure will result in a laser net. The laser pointer is moved by two RC servos controlled with a PWM signal generated by a 16F876A PIC microcontroller.
Once the circuit is done, the program can be configured to change laser speed, offset between lines and net size.

For the video I used a 7.4V LiPo battery, the voltage is regulated by a 7805, and the laser pointer uses one of the PIC 5V outputs with a 25 Ohms resistor.

State of Your art: What makes an artist improve?

Paths to consciousnessHow many times can you overcome the same challenge feeling the satisfaction you had the first time? Some people only need one or two times, others can keep repeating the same thing for a long time and still enjoying it. This number will depend on our degree of demand and perfectionism, which in practice is the time that takes us to need a more complicated challenge, and see what we’re capable of. That’s why I think artists or professionals learn and get results at different rhythms.

From my experience, the learning curve is based on what I’ve just mentioned and two more factors that I’ll explain now, but in a different perspective than the typical “learn, practice, learn, practice”. What I find more interesting is what do we think about the results we’re getting. Are they good, bad? Are we proud of them? Which aspect would have a better result?

The first and more important factor is what I call State of Your art. If you were asked to position your work in a “quality ranking” among everything you know about that subject, where do you think it would be? You’ll probably think there’s a lot of people already better than you at that, and still more if you’re just beginning, but knowing the State of Your art will allow you to have an imprecise but also global reference, and wou’ll not be disappointed when you find out somebody else had the same idea as you and executed it in a much better way, or with a slight difference that you wouldn’t have thought of. Knowing the State of Your art won’t give you so much satisfaction when creating something new, but neither you’ll be disappointed if you discover that your idea was already done, because you already knew that this could happen.

How do you know your position in the ranking? Suppose there’s still a lot to see, that there’s somebody better than you, and that you still have a lot to learn. Thinking this way won’t give you an exact position, but I believe it’s an appropiate attitude to have. I find interesting and useful to read and talk with other professionals, to see how they work and also to learn and inspire myself, but I also think it’s important to develop a personal style that, while being influenced by some others’ works, are the product of our vision as an artists and professionals.

The second factor which I find necessary to improve is self-criticism. Just before creating something, many times comes the initial euphoria of “This is amazing!”. It’s fine to feel this way at first, but then it’s necessary to place your new work in the ranking of what you know and settle down.

I think the previous factors allow us not only create better art, but also better products and services, as long as exists a continuity and passion in what is being done, without thinking about getting huge results, just to improve, do someting meaningful and setting personal goals, the rest will follow.
