Tilt-Shift Effect a.k.a. Miniature Faking Effect

I always loved miniature models of cities or objects, both in real world as well as in a computer. The process of making them is an art of perfection, like the effort one has to put in to grow a bonsai tree.
I was really amazed to see this picture while I was browsing through flickr pages. I was thinking, “This guy must have put in a lot of effort to make this model” when I saw the footnotes. It said “post processed the tilt shift effect in photoshop” which meant, I can create this effect using photoshop. I didn’t believe it at first. But, after around 5-10 minutes of Google-ing and around 20 minutes of photoshop-ing, I had my first tilt-shift image ready. I used a random snap at first but later tried it on a real photo. Here is a small tutorial on how to do it in photoshop. You can find many tutorials in net and the main steps are same. I have added some tips from my personal experience.
According to Wikipedia, “Miniature faking is a process in which a photograph of a life-size location or object is made to look like a photograph of a miniature scale model. Blurring parts of the photo simulates the shallow depth of field normally encountered in close-up photography, making the scene seem much smaller than it actually is; the blurring can be done either optically when the photograph is taken, or by digital post-processing. Many faked-miniature photographs are taken from a high angle to simulate the effect of looking down on a miniature.”

1. Initial photo. I had to go up to the 6th floor to get enough elevation required for this effect. This is the main requirement for tilt-shift effect. If the photo is taken from a sufficiently high altitude, it’ll give the impression of looking down at the model.

2. After pre-processing. I did some pre-processing to make the image look a bit artificial. The properties I manipulated are Levels, Exposure, Variations, Shadows/Highlights and more importantly Vibrance/Saturation.

3. Enter ‘Quick Mask’ mode either by pressing the quick mask button (highlighted in the image) or by using the shortcut ‘Q’

4. Select the ‘Gradient Tool’ and then select the ‘Reflected Gradient’ as shown.

5. Decide which part to highlight in the image. Then click & drag a straight line (press down the ‘shift’ key) from that point to top or bottom.

6. When click is released, the area will be selected in a gradient red color.

7. Exit ‘Quick Mask’ mode by pressing the quick mask button (or ‘Q’). This will give you a ‘marching ants’ selection in the image. We are going to blur the selected area to simulate shallow depth of field.

8. From the ‘Filter’ tab (as shown), select ‘lens blur’.

9. Now this is where you can get creative. The values I have used for this tutorial are shown here. You can try playing around with the values for different results. But, I’ve got to warn you, it might take some time (depending on your graphics card) for the preview to load, especially if its a big image.

10. When you are satisfied with the image in preview, press ok to exit. Deselect the selected parts using ‘Ctrl+D’ and you are done.

11. The finished ‘tilt-shift’ed image.

These are just the main steps in creating the effect, but there is more to it and I am still learning. The image saturation and the shadows/highlights play an important role in making the image look like a miniature model. But the most important factor in my opinion is the contents of the image. If its a picture of nature, it might not look as ‘perfect’ a miniature model as compared to an image with lots of objects or people. See the difference for yourselves in the photos below.

Designing a logo

I do bits and pieces of painting/drawing once in a while and I love almost everything that had anything to do with computer graphics. Electronic games are my weakness, but that’s mainly from a user point of view. Other interests are graphics programming, designing etc. Creativity has its own advantages. You can create, destroy or modify almost anything you want. More than that, I like playing God. So I jumped right in to the opportunity to design a new logo for our organization and my logo is selected as the new official logo.
Our organization - ARL - was on the process of revamping its website and the employees were given the choice of coming up with a new logo. We were free to come up with anything. No bounds were there. But it had to be agreeable to others in the lab. The main factors I had to keep in mind when designing a logo was that it should be easily printed on paper (in color, gray scale and black & white) as well as clothes (embroidery), stationery items like mugs, pens, plastic etc. Also the colors should stand the test of time and space (stretching, different media etc).
In the beginning, I was not sure whether I could do it. Finding the starting point was my main challenge. I had to formulate and idea and then start off from there. I kept thinking about it for some time and decided that I will start from where my predecessor stopped - the old logo. My plan was to rebuild the old logo first, may be with minor modifications in phase 1 and then add any new ideas as it comes along my way.


Old Logo
I looked at the old logo and asked myself, what are the key elements in there and what can I do to make them look better. After some thought and discussion with my professor, I decided to concentrate mainly on the following.
1. Make a new earth with glossy surface and a good reflection (inspiration: windows vista aero interface)
2. Make the bubbles, bubblier.
3. Decide whether to retain the waves or not. If retaining, try a different look. (The shell & waves are adaptation from the TMSI (Tropical Marine Science Institute) logo, to which ARL is affiliated to.)
4. New fonts for ‘ARL’.
I started with the earth part. The only tool I have used for the whole process is Adobe Photoshop. (Both ver. 7 and CS4). I searched the net for tutorials for a glossy globe and found this one.

And that’s from where I started. The result of my first experiment looked like this.
Ok, now that I have a place to start from, I started playing with other factors like the bubbles, fonts, waves etc. Some of the tutorials I have used are given in the reference section. I downloaded custom brushes, fonts etc. My reconstructed logo, with new bubbles and font, but without the waves looked like this.
Ok, phase 1 is over. Now for the next phase, I wanted ideas, something that everyone will notice from the previous logo, at the same time, retaining the key elements of the old logo. That’s when I noticed the color combo of NUS website. Orange, blue and white. That’s from where I got the idea of using different colors. Ok, orange and blue, one of my favorite combos and at the same time, a theme which goes along with NUS website theme also. I had to start the logo all over again. The result looked much better than the green one (from my point of view).
I also had to create the ripples that originate Singapore. For that I found many methods/tutorials, but none was getting close to what I wanted. Then my professor sent me a link to try and voila! It worked. Also it was he who suggested keeping a simple font.
The result of my earlier experiments looked like this.
Another of my experiment with waves and without ripples resulted the following.
I ignored the idea of waves in the beginning itself as I was not able to do a nice work and it’s a bit difficult job and I was too lazy for that.
The above logos were used to collect feedback. Some of the main feedbacks received were, the ‘ARL’ text is not proportionate to the size of the globe, the gradient color scheme is difficult to do embroidery on t-shirts, the ripples are too small, since the ripples are there in the land, it given an impression of tsunami (We wanted the ripples to represent acoustic waves - showing the relation to our research domain) etc.
I redesigned again and came up with the final logo with bigger ripples explicit to the blue region (water) and a bigger single color ‘ARL’.
Final Logo

And that’s how this logo was born. Different versions of logo were made with different sizes, background (alpha channel), color/gray scale etc.
I never thought I will end up with this logo when I started. But when looking back, I feel great about this project. Special thanks for my professor who helped me from the starting point till I finished this project, with valuable advices and suggestions.
Along with the logo, I have also designed a simple map to reach our facility which you can find in the ‘contact’ page in our website. It was real fun making it.
