Blender modeling tutorial

Today we have a guest tutorial author!  My younger brother, who has recently joined me on the journey of teaching ourselves Blender (a free, open-source 3D modeling software), created an excellent, thorough tutorial of how he created a simple, yet highly maneuverable human model.  This model can be easily animated or posed.  Because the tutorial is composed entirely of pictures, with step-by-step instructions on each image, the entire tutorial is rather long for a traditional blog post.  Instead, we assembled it on a separate page, which can be accessed by the tab at the top of this blog, or by clicking the link below:

True beauty and the ethics of Photoshop

I find it fascinating how fake the models are that we see in magazines and ads.  Most models look like ordinary people before the makeup, lighting, and particularly the Photoshop adjustments, transform them into these artificial and flawless... what shall we call them?  Gods and goddesses?  Angels?  Aliens?  Whatever they are, they are not natural and they are not real.  Here are a few examples I pulled from www.hemmy.net:

(The original image is first; the Photoshop image is shown after.)

Is it just me, or do these pictures make you feel sick?  In each of these cases, I think the original model is physically attractive.  None of these photo edits make sense to me, with the exception of the blemish that was removed in the second picture (with a blemish that obvious, I think I'd remove it, too!).

And yet, it is these edited, counterfeit pictures of models that so many people -- girls and women in particular -- subconsciously look up to as standards for attractiveness and beauty.  According to a study in 2004, only 2% of women think they are beautiful (www.dove.co.uk).  This is a shockingly low number, but should it really be surprising, with the repulsive way beauty has been contorted by our media?

"I wish I looked like such-and-such an actress!" a woman may moan.  But I would plead in response:  "Please understand that you probably do!!"

If you haven't seen Dove's video "Evolution", you need to.  This is another excellent glimpse into the phony world of modeling:



Now, don't misunderstand me: I am not necessarily opposed to editing photos.  I've done it myself on a small scale.  I understand; sometimes the lighting of our photos isn't good.  Sometimes models wake up on photo day with big zits on their foreheads (GACK!!).  That isn't what I'm talking about.

What I am talking about is morphing someone into an unnatural, impossible non-human that no person could ever physically rival in real life.  I'm talking about making aliens into our standard for beauty.  I mean, you might as well make this our standard for beauty (I am talking about the left half of the picture, of course):

By the way, I have no idea what this book is about, I'm not endorsing it, and I couldn't tell you if it was extremely inappropriate or terribly written. I'm just borrowing the cover to emphasize my point... 

As computer artists, we have these questions to ask ourselves:  What is most important or valuable, as we make our computer art, or edit our photos?  What is our highest priority in this matter?  What should be our highest priority?  What power do we wield, as computer artists and culture influencers, and what are we personally doing with that power?  Let me be more specific:  Are we doing more harm or more good with that power?  And if we are doing more harm... what should we do differently so we are doing more good?

What do you think?

Bryce/Photoshop tutorial: underwater iceberg

© 2012 Brianna da Silva

This tutorial is an example of combining Bryce and Photoshop to create an image.  (By the way, if you're interested in 3D design and Bryce, the software makers are offering it for free for a limited time!)  The concepts in this tutorial can be applied to the creation of many other Bryce/Photoshop images.

I wanted to make an image something like these pictures (these were just random photos and drawings I pulled off the Internet):



I wanted the classic tip-of-the-iceberg picture, showing the rest of the iceberg underwater.  How would I go about making this, I wondered?  I knew that Bryce did not have a split-screen, half-above/half-underwater capability.  In Bryce, you're either above water, or you're underwater!  So, I decided to use a combination of Bryce and Photoshop (mostly Photoshop) to get the effect I wanted.

Phase 1: Bryce


Step 1: Above water

First, I created the above-water image of the iceberg.  I did this by creating a lattice (learn more about lattices in a former post), which I made really big so the details later would look more realistic.  (General rule of thumb: If the object you're making is big in real life, make it big in Bryce!)

I gave the lattice the iceberg material (go figure!).

Then, I created a water plane, and moved the lattice down so it was roughly halfway "submerged" in the water.

I gave the water the material called deep blue.

I also gave the sky a preset called The Big Deep for lighting purposes.  (Mostly so the water would look dark blue, which didn't really matter anyway.)

Next, I duplicated the lattice a couple times, making smaller icebergs in the distance, just for variety in the picture.

I made these icebergs a little rounder-looking, by first opening the Edit window (found by clicking the E that appears next to an object when it is selected), clicking New under "Editing Tools", and drawing a rough, blobbish shape with the paint tool.

For a more detailed guide on editing terrains and lattices, I recommend this tutorial.  A couple things to keep in mind: In the tools on the left, you can change the size and softness of the brush (I used a big brush with medium softness), and you can adjust the elevation of the brush with the slider.  The higher the red dot, and the lighter the color of your brush, the higher it is; the lower the red dot, and the darker the color of your brush, the lower it is.

Finally, I got my view where I wanted it -- just about level with the water line -- and rendered.  This was the image I got:

Step 2: Underwater


The next step was to create the underwater view.

First, I saved the document as a new project, so I wouldn't loose my first work. Then I deleted the water plane, moved the icebergs up and zoomed out so I could completely see them, and stretched and enlarged them so they would be bigger than their above-water counterparts.

I used this tutorial, found though googling, to change the atmosphere so it had the allusion of being underwater.

This was the result: (Ignoring the cloud and sky; that wouldn't be used in the final image)

Later, I also temporarily removed the icebergs and rendered an image of just the "underwater" scene (I found out, while working in Photoshop, that I would need it):

Phase 2: Photoshop


Now the real work began!  This phase took more time, by far.

Step 1: Basic image


I used the marquee tool in Photoshop to copy the underwater portions of the iceberg, and then paste them on the above-water image.

Using the marquee tool again, I took the plain underwater image (without the icebergs) and put it behind the underwater iceberg layers, to fill in all the gaps.  (Learn more about Photoshop layers here.)

I erased the water around the underwater iceberg layers, stopping right at the edge of the ice.

Step 2: Dark line


I added a dark blue line at the edge of the water, to make the edge look sharper and a little more realistic.  Tip learned: Hold down the shift key while painting, to paint in a straight line!

Step 3: Light rays

My brother suggested I try making light rays in the water, so I gave it a try.

I chose a soft brush, gave it a white color, and painted diagonal streaks in the water.  I gave the light ray layers a very low opacity (8%), and used a soft eraser to taper the streaks to a point. 

Step 4: Darkening water

I made the water get darker as it went further down by painting horizontal streaks, using a soft brush, and making the color just slightly darker with each stroke.  The result was a smooth, subtle transition to a somewhat darker blue.

At last...


Finally, as a sort of small, side adjustment, I darkened the horizon a little by painting a light gray layer with a low opacity.

The picture still wasn't perfect.  The water probably should have been darker, and the iceberg ended up with a strange purplish hue (probably a poor choice of lighting... lighting in Bryce is next on my list of things to learn!).  However, the result was more or less what I imagined.  Regardless, it was a fun example of how a Bryce image can be completely transformed in Photoshop!

Basic Layers in Photoshop

One of the most foundational concepts for Photoshop beginners to understand is the use of layers. In this video tutorial, I give a brief demonstration of how layers work.

FREE! DAZ Studio Pro, Bryce Pro, & Hexagon!

"Borgimi Village", created with Bryce 7. © 2011 Brianna da Silva

Are you interested in getting started with 3D art? Well, I'm excited to share the news that DAZ 3D is offering three of its programs -- DAZ Studio Pro, Bryce Pro, and Hexagon -- for free!


I don't know about you, but at first I found this a little suspicious, and suspected there were some sort of strings attached. But I went ahead and downloaded Bryce Pro and Hexagon, and wallah... it really is just free software, no hooks. (With the exception of a small sort-of-hook, which I explain below.)

This is over $800 worth of software for nada. For a limited time, of course.

So, what are these programs, you may ask? In a nutshell:

DAZ Studio Pro: 3D art and animation 
**Personal notes: Beware, there is a catch with this program. From what I can tell, this program predominantly uses prebuilt DAZ models, which you have to buy. And also, a word of caution: The human models for this program start off nude, and it's rather graphic. I haven't actually used DAZ Studio, so I could be a little mistaken about how it works. For now I'm just toying with Hexagon (see below), in the hope that I can create my own models that are neither graphic nor costly. But... the benefit of DAZ Studio is that it's easy and fast, for those who'd rather buy models than make them on their own!

Bryce Pro: 3D landscape and animation
Personal notes: I strongly recommend this software; it's not very user friendly for those that are new to 3D -- personal experience! -- but once you get the hang of it, it enables you to make some pretty cool art! And that's especially awesome when it's free!

Hexagon: 3D modeling 
Personal notes: As I said above... I'm drawn to Hexagon because it appears that, so far, I can create my own models without using DAZ Studio's graphic/costly ones. I still haven't actually gotten to the stage of making models, though! :-)

If you want some links to get you started with these programs, check out my Learn more page, where I have links to some other tutorials and resources I recommend.

Happy 3D-making! :-)

The 6 stages of learning a new software

It seems that every time I learn a new software, I go through these same stages.  If you're in Stage 2 or 3, maybe this will give you hope. At the very least, maybe this will give you something to smile about.


The 6 stages of learning a new software

  

1. Ecstasy. You buy your new software. You are bursting with hope and expectation of all the awesome things this software will enable you to do.
2. Confusion. You don't know how to use the software.
3. Frustration. You are learning how to use the software. Sometimes you want to blow it up. Your hope has vanished like snow in a fire; you will never be able to use this software; it's impossible; it's stupid.
4. Rejoicing. Slowly, you're starting to understand how to use the software. You become increasingly comfortable and fluent with it. Your friends and family think you're weird, as you rejoice every time you successfully do something with it. (This is, probably, the funnest stage -- and maybe the funniest as well.)
5. The finish line. Gradually, before you know it, you're practically a pro. You are completely comfortable and fluent with the software. It becomes like a third arm, an extension of you -- like driving or walking. There's nothing you can't do... although admittedly, the software is less exciting now.
6. Repeat. One of your friends buys the software, and you can't understand why it's so hard for them.
