Panoramic Deep Zoom – Question of the Day

I’ve had lots of folks asking me about how some sites (such as Hard Rock) were able to stitch photos together to effectively make a panorama, which can then be deep zoomed. Think about it – say you have a 4 MegaPixel camera, you can only take a 4 megapixel shot, which, when deep zoomed will not look as good as if you had (for example) a 400 megapixel camera.

But what if you could take lots of close-up shots of your object and stitch them together, effectively making a picture with many more megapixels (there’s the alliteration again!) than with a single shot?

Well, there’s a feature of DeepZoom Composer that you may not already be aware of that allows you to do just this.

So, as a simple experiment, I used a very cheap, low-res camera to take 5 shots of a painting that is hanging in my house that I bought in a market in Beijing. The pictures are here:

As you can probably tell, I’m not much of a photographer, and didn’t have anything by way of decent lighting or anything like that. I just went snap snap snap and took this using only the ambient light in the house and a cheap digital camera.

So, next I fired up DeepZoom Composer and created a new project. I added these 5 pictures to my workspace and selected the Compose tab. I dragged the 5 pictures onto the space and DZC stacked them. If I right click on the stack, I get an option to ‘Create Panoramic Photo’

Select this, and DZC will start doing its magic of reading and stitching the photos. I’m using a Vista Box with a WEI of 3.5 and it took about 30 seconds to create the panorama, save it to disk and re-import it to DZC.

Once done it will present a tool that allows you to crop the image. As you can see from my pictures, the camera wasn’t held very straight (deliberately, I might add) and you can see varying borders on the painting.

Once I’m done, I can save the Cropped Image (guess which button?) and add it to my composition. Once you’ve done this, you can remove the source images from the design surface and output the deep zoom project.

You can see the finished solution here, and this is literally 5 minutes work. Can you imagine what a real photographer could do with this if they spent a little time on it?? :)
