Hi all,

I have Sony’s andriod cellphone with 8MP camera. I also own Nikon D5100. While it is fairly easy to photograph shallow DOF with my Nikon, I have not been able to find a way to get this effect with my camera phone. Has anyone tried it out?

Hello Ned,

I would first like to explain you how the depth of field works. The depth of field depends on several factors and aperture settings are one of them. The other factors are the lens’s focal length, distance of subject from background and distance of subject from the camera. You can basically not control the aperture or the lens’s focal length, you can eventually get a shallower depth of field by minimizing the difference between the camera and the subject. When you move the camera closer to the subject, the background will fall out of focus. So you will get sharp focus on the subject and the background will be blurred, just like the background blurs for human eye, when we focus on the subject closer to us.

Hi Ned,

In addition to what Ned says, if it just the effect you are looking to emulate directly on the phone, you could try using an app like ‘after focus’ that allows you to blur parts of the image.

here’s a link to the free app:

Hi Ned,

 

I had a Sony Aino 8Mp camera back in 2009 which has an excellent feature called “Touch Focus”. It helped me to focus on just the desired part of the image & let the rest Out of focus.

You can search over the web whether your sony phone supports Touch focus or not?

Thanks for the helpful tips.

Adam Miller: I tried getting close to the subject. Even though the background blurs, but that blur is minimal. I was wondering if I could smoothly blur the background as it happens when using 200mm zoom at f/5.6.

Aj Sharma: Thanks for sharing this wonderful app. I’ve downloaded it and its fun playing around with it. In fact I am able to get the exact amount of blur I want. But I was thinking if I could control it while shooting itself.

YogiMaini: I’ve Sony Xperia Ray. Even though the specs say that it features Touch focus, I am not able to figure out how it works. But I have noticed one thing in my photos that sometimes accidentally I am able to get blurred background, but I am not able to figure out how it works.

I think for now I will go with After Focus app.

Thanks :)
