Serial Number Hand 9 Tutorial' title='Serial Number Hand 9 Tutorial' />DSLR Bokeh Tutorial robertsdonovan. It seems that many Flickrites out there are struggling to get good bokeh shots. The good news is that shooting bokeh is one of the easiest photographic techniques to learn. Unfortunately, it is also one of the hardest to master. Here I will attempt to get you started with the basics. Youll have to do the mastery part on your own Bokeh pronounced boke aay or boke uh I prefer the latter is the out of focus or blurry areas of a photograph. Wikipedia has a much more detailed description of the definition of bokeh thats worth a read. On Flickr I find most people use the term to specifically describe out of focus highlights in a photo. For the purposes of this how to well focus pun intended on out of focus highlight bokeh. The photo above made the Front Page of Flickrs Explore last week. I wish I could say that this was a difficult and challenging shot that called upon all of my skills as a photographer. The truth is this was one of the easiest shots I took that night. These small aperture long exposure shots were a lot more difficult to get right The secret to shooting bokeh lies in its definition out of focus highlights. You need three things to shoot bokeh pin point highlights, a large aperture and a short focal distance. When I say pin point highlights I mean small light sources. Trying to shoot a large area of light like a window or fluorescent light does not typically produce the type of bokeh balls that we are looking for here. Small lights like Christmas twinkle lights are an obvious source, but any light source that is far enough away will become infinitely small and can produce bokeh. I find street and car lights in the distance at night make wonderful bokeh. Pentax A 5. 0mm f1. SMCNext, we need a large aperture. For the novice, the aperture is the opening in the lens that controls the amount of light that makes it through the lens and shutter to the filmsensor. The smaller the f number or f stop the larger the opening. This is usually expressed as f5. Read more about aperture here. Typically the larger the aperture the larger the bokeh. Fast lenses below f2. Pentax A 5. 0mm f1. SMC are ideal for shooting bokeh and is the lens I use for most of my bokeh shots on Fickr. Harry Potter And The Half Blood Prince Full Movie Mp4.

Serial Number Hand 9 Tutorial' title='Serial Number Hand 9 Tutorial' />That is not to say that one can not get great bokeh using lenses with a smaller maximum aperture like the typical kit lenses sold with most entry level DSLRs. The trick is to make sure you are using the largest aperture possible smallest f number. To do this I recommend switching your camera into Aperture Priority mode typically labeled A or Av on the program mode dial and dialing in the smallest f number possible. With most kit lenses this will be f3. Here is another Explore bokeh photo of mine shot with my kit lens at f3. The other reason that you want the largest possible aperture your lens is capable of is to ensure that your bokeh is round and not faceted. You see, most lenses use 5 7 straight aperture blades to create the variable opening in the lens. Bokeh takes on the shape and size of the lens opening so smaller apertures will produce smaller, faceted and generally less pleasing bokeh. There are exceptions to this rule as most high end lenses use curved aperture blades that keep the aperture opening round at all f stops. However, if youre shooting with a 1,5. Canon L series lens I trust you already know how to shoot bokeh Aperture openings on a 6 bladed lens mouse over for setting Bokeh shots at different aperture settings with this lens mouse over for setting The last component to getting good bokeh shots is the focus distance used. I have found that the shorter the focus distance to the foreground subject, the better the background bokeh I will get. The idea is to get as much distance between the subject and the bokeh producing highlights. Also, the closer you are focused to the camera the shorter the depth of field DOF will be. This ensures those lights way off in the background will be nice and blurred out. The focal length of the lens is also a consideration. Depth of field is basically a function of focal length, distance to subject and aperture. At a given aperture and distance longer focal lengths result in shorter DOF. A short DOF is what we need to effectively blur the background highlights to produce bokeh. Getting close to the foreground subject and zooming to the longest setting on your lens will likely put you where you need to be to capture killer bokeh. Here we have an example of close focus on the foreground subject coupled with a wide open aperture and longer focal length to create bokeh from small lights in the background When I took this shot I was at the minimum focus distance for my 5. The white gold colored here twinkle lights were on another Christmas tree approximately 8 1. I focused on. The other smaller colored bokeh highlights were from other lights on the same tree that I focused on. TUTORIAL Now that Ive rambled on ad nauseam about all the intricate details of capturing bokeh, lets get on to the part where you actually go do it For DSLR users point n shooters will have to wait for another tutorial Set your camera to Aperture Priority mode A or Av on the program dial. Select the smallest possible aperture f number for your lens should be f4. Switch your camera to manual focus and manually adjust the focus to the closest setting. Zoom your lens to somewhere around 5. Find some nice points of light at a distance of 1. Christmas tree is the perfect subject this time of year. Fire away If you get a shutter speed thats too slow ie less than 13. ISO up to 4. 00 or more. If you do the Christmas tree thing what you should get is something like this Depending on how dark the background is darker usually better you might have to dial in some exposure compensation to get your bokeh to really pop. This image looks like it came out fine without any, but I often have to dial in 23 to 1 EV for my 5. Pentax K1. 0D. Next, try putting a subject of some sort in front of the camera at the minimum focus distance or there about with the bokeh highlights in the background. Itll take a little playing around with subject matter and lighting both foreground and background but in no time you should be shooting bokeh like a pro For more examples, be sure to check out my bokehliscious set on Flickr.
