Well this is it! The experiment is over……at last I’ve finished my bottle.
My goal was to make a photorealistic image of a perfume bottle (that I have at home) just using an open source and freely available 3D program called Blender. Not only should it be photorealistic, it was supposed to look glossy, like the ads you see in magazines.
It was quite a journey…
– First I made the wireframe of the bottle. This means that you have to draw the shape of the bottle. Next I placed the virtual lights and gave the model its material (glass and plastic).
So far so good, but I wanted to add that ‘something extra’. I decided to add a water splash. This is very common in commercial photography, but alas, the water simulation in Blender was nice, but not realistic enough for my taste. Being reluctant to drop the water theme, I had to think of something different. So I placed the bottle in the middle of the ocean. Although it looked nice (at least that was what I thought), I was getting further away of the glossy magazine look. Also a bottle cannot stand upright in the sea, unless it has divine properties so to speak.
It didn’t make any sense, really. To make it worse, I have to take a real photograph of the bottle so that I can compare the two images. There was no way I could replicate the photograph in real life (well I could, but I have to a photograph at full sea, at dawn with studio lights and a platform just below sea level where I can put the bottle on). Therefore I decided to go back to basic and created a virtual studio environment. I used a reflective surface and let the lighting do the trick. That’s it! You can see the result below. What do you think? Is it photorealistic?
I also tried two freely available external render: “yafaray and Luxrender”. On their websites you can see some amazing images. I really I think they are promising render engines that integrate with Blender really well. But it’s not for me (just yet). They are both much slower than the Blender render engine (Cycles) and more difficult to set up. Luxrender was the most problematic. Sometimes it rendered an image but sometimes it didn’t. A bit hit and mis. Probably it is something I am not doing right, but I still have to figure out what that might be. I also found Yafaray too ‘techical’ to set up. I just want to hit the ‘render’ button and see the image appear, instead of setting up Photon maps and AA passes and what not. This is terminology a photographer doesn’t understand. Not really user friendly in my opninion. But hey it’s free and the results (when you got your chops down at least) are really terriffic, so I’m not complaining.
So what’s next? Well nothing really, this is it. I’ll make a real photograph in the future to see how it compares to the fake one, but that’s for another blog.
If you want to give it a go yourself, you can download Blender, Luxrender and Yafaray here:
See you next time…
Hello and welcome to part five of “the making of a commercial still”.
Last time I was really excited because I discovered a feature in Blender called “the fluid simulator”. I had seen a couple of demos and it looked really promising. I envisioned the perfume bottle surrounded by all sorts of water splashes, giving it that really slick look.
So last week I fiddled with the settings and generated dozens of splashes. Big ones, small ones, a lot of drops, few drops etc. I’ve dropped all sorts of objects in virtual water, just to see what kind of effect it had. Actually what you do is, you make a small little animation (about one second) of an object hitting the water. The program calculates each frame, one by one. At the end you can select which frame you are going to use for the image still. This is a really time consuming process. To generate a high resolution splash, you have to let the computer render overnight.
And the results were…..to be really honest…..a little disappointing!
Although it generates all sorts of splashes, it doesn’t look realistic enough, to my taste.
I’ve included two photo’s so you can see for yourselves:
I have set the fluid to act like water (oil is a possibility too), but it doesn’t look like water to me. It has a plastic, or glue-ish kinda feel to it. I don’t know what it is? Not only that, but it generates all sorts of weird artefacts. You can see in the upper picture that the small droplets have these black ’things’ around them. Like there is some bug in the program.
Anyway, I don’t consider this to usable for realistic and commercial use.
So it’s back to the drawing board. First I have to think about how pimp this image in another way.
Next time you will see the results.
This is part one of an experiment I am going to do over the next month(s) or so. I am going to take a commercial slick looking photograph of a perfume bottle, without actually taking a real slick looking photograph! I’m entirely going to use CGI to create the bottle and backdrop.
This will be my first photograph that is 100% CGI.
The aim is to make a convincing photograph, such that it is (hardly) noticeable that it’s fake, using available open source software. My weapon of choice is Blender. This 3D software has changed a lot the last couple of years, with a lot of added features and a large user base. Also it’s for free, and being Dutch I couldn’t resist this opportunity;-)
So how far can I take this project with free software? To answer this question I will not only make a CGI version of the perfume bottle, I will also take a real picture and compare the two. See what the differences are, not only in results but also in ‘feel’ and process etc.
Now this is what I’m going to make a photograph of. L’ eau de toilette called “Narciso Rodriguez for her”:
Somehow ‘Narciso’ and the blackness of it all inspires me, like a Greek tragedy of some sorts. And yes I will try to make a somewhat more exciting picture than the one you are currently seeing.
To make a 3D image you have to go through several process steps:
1. ‘Drawing’ the objects, also known as modeling, or creating a wireframe of the bottle;
2. Lighting the objects in 3D space;
3. Create the materials that the objects are made of;
4. Bringing it all together and make a final ‘photograph’ of the objects in 3D space. This is called ‘rendering’
Next time, I will show you the wireframe of the perfume bottle and the other objects. Haven’t made the image yet it’s very exciting to see what I will come up with and if this will be any good? So stay tuned and you will find out.
By the way if you have any suggestions or nice ideas for the so called commercial shoot, you can post your comments below. And I will try to incorporate them!
Lately I’ve been experimenting with 3D rendering and how to combine this with photography.
I use an open source program for my 3D experiments called ‘Blender’. I have to say this is a really wonderful program. Although I cannot compare it to other professional 3D packages out there, because I haven’t used them, it’s a really powerful tool that can produce photo realistic images.
Photo realism you say? Well yes……if you are really good 3D rendering that is. This raises some philosophical questions, that I will discuss another other time, but for now I’d like to present you with a quiz. Can you determine which of these next five images are real photographs or are 3D renders? Which images are the fake photographs? I will give you the answer next time, but for now:
If you know which images are real, post the answer in a comment below. Next week I’ll give you the answers and the people who made these images.
