![]() In an answer to another question, I've listed some other techniques to achieve good background separation, most of which are usable with a point-and-shoot. use a technique called " Brenizer method".need to have a point and shoot with large sensor (such as Sigma DP2, Fuji X100 - you wouldn't be asking if you had one of those).In short, the answer is yes, it can be done, but. I had a short subject distance and ensured the background was both far away and not too busy looking. Of course, if you want to be able to have better bokeh in more situations, you'll need a larger sensor for what is called increased DoF control, or do an extreme version of this. That said, even with a P&S, you can get reasonable bokeh with composition, IMHO. Once you have a larger sensor, then getting good bokeh depends on the lens but also composition: selecting the a good background and ensuring that it is a the right distance away. ![]() So while the lens matters, the sensor size matters more. The small sensor is only taking a small part of what a larger sensor would take (see this). Less of the background will be shown, limited more to what is directly behind the object and usually further away. Note that increasing the focal length can allow you to stand further away for the same object framing, which will compress the perspective. Basically, when compared to a larger sensor, a smaller sensor will need to be closer to the object or have a longer focal length for the object to be the same size in the picture. The rest are functions of the sensor size. The f-number is a property of the lens, essentially how large the iris or opening is. Depth of field depends on several things: f-number, distance to subject, focal length, and the circle of confusion (determines what can be perceived as in focus or out of focus). In addition, the the shallower the depth of field, the quicker things become out of focus when moving away. Something is more out of focus the further away it is from the plane of focus. Most details that are only a bit out of focus don't look too pleasing. One pre-requisite to pleasing bokeh is to have sufficiently out of focus areas. I just gave it a shot with my camera, and it does work.īokeh is subjective, and all cameras can create bokeh. So your two points of control are focal length and subject distance. ![]() So to blur the background using a P&S, you’ll get your best results if you zoom in all the way, focus on something close (you don’t want to focus out to infinity), and have a background that is much further away. As I said in the tips, a short focal length will produce an image with nearly everything in focus. They create an effective focal length much higher due to the small sensor size. My P&S has a focal length range from 6mm to 18mm - which is very small. The problem with creating a shallow depth of field comes from the fact that the sensor is so small, and as a result the lens is close to the sensor - thus creating very small focal lengths. It also helps if the camera has zoom, as most P&S cameras do. If the camera has manual controls for aperture, that definitely helps. Yes, but how much will depend on the camera. There's a good answer from Brian Auer, which I'll reproduce here, as it pretty much covers the problem you're trying to solve: ![]()
