focusing on flower blur on backround

hi guys ive seen in some videos where the image for example a flower is focused on then blurred and the backround becomes focused i was wondering if the pmw ex1 does this and how
 
It's as simple as Peronne said. Put it in manual focus, use as shallow of depth of field as you can, best effect while zoomed in from a distance... manually turn the focus ring to where your foreground flower is sharp and then turn the focus ring to where the background becomes in focus.
 
You need to use a large aperature (wide open or f1.9, f2.8) to decrease the size of your focus area (depth of field) to best get this effect on the EX-1.

Google "depth of field" to learn about how this complex idea works. It is at the heart of all camera operation.
 
Welcome to the forums.

The effect is caused by the interaction of the size of the sensor, the size of the aperture and the length of the lens. Its more pronounced with a bigger sensor, wider aperture and longer (tele) lens or zoom. Hence the above advice.

The EX1 is a little better at it than most prosumer and consumer cams because it has a larger 1/2" sensor, rather than a 1/4" or 1/3" sensor. Just open the aperture and zoom in. At the same time its a very high resolution camera in its price category.

People also use 35mm lens adapters or DSLR cameras to get the effect, but they lose resolution when they do that.

The aesthetic quality of the blur is also called bokeh, which comes from the Japanese word for blur. :)

Have fun and surf around the boards.
 
Not another rack focus shot. LOL just kidding Mark.

Hey who did your VO on the Global Warming clip? Great voice quality.

Yes, these rack focus shots are getting ridiculous, aren't they? I just wanted to show off my daughter's parrot. :)

I do all my own VO's. I've been doing radio work for nearly forty years. One of the challenges is to learn how to speak in a totally accent-neutral manner, otherwise it's hard to get into many markets. I still host a weekly radio show, which airs on a Connecticut FM station, Adventures in Anime Music. You should hear me do my Tony Marvin impression! (He sounds like Tony the Tiger on the cereal commercials of the 1960s "They're Grrrrrrrrrreat!"). Here's me doing my impression of Santa, at the end of this Merry Christmas Penguins clip.

I'm planning to adopt or buy an African Grey Parrot (probably Congo variety) and teach it to speak. Then I can record some phrases with the parrot and splice it together to make a sort of Lawrel & Hardy type banter. Not too many times do you hear a parrot co-hosting a radio program. :)
 
Sounds like fun with the parrot. You could give James Earl Jones a run for the money.


I also did the VO for the Unsound Audio: What's Wrong with the Sony HVR-V1U video clip on Youtube.. the one that got me kicked off of CreativeCow 3 years ago. :)


Yeah, the parrot is a lot of fun. We share a bagel every night during my coffee break and he likes to watch movies while sitting on my knee. His head turns as he follows the action on-screen. He'll sit through a 2 hour feature and watch every second of it. I always play the director's commentary afterwards, hoping he'll pick up the language by hearing/seeing different people talk. I plan to start using him as a creative subject for some videos. While he's not quite as entertaining as Yo-Yo the African Grey who does telephone sounds and conversations and goes "weeeeeeeee!!" like he's having a parrot orgasm, my daughter's cockatiel does have his unique and often amusing antics, which I'll try to catch on video.
 
I think 5 people have told you how to do it and how it works.

[The best way to learn a camera is to play with it a lot after you read the manual. My first good camera I set aside every lunch hour for two months to try every combination of every switch. It helped tremendously.]

a) Open the aperture wide. Turn off the all auto button (left side of camera towards rear.) Put iris in manual (left side of camera towards middle.). Turn the first ring until the picture is very bright. Use the ND filter switch (left side of camera towards front) to tone it down if the image is too bright.

b) Step back from your subject, way back, and zoom in.

It helps too if there is some distance between what you want in focus and what you want out of focus.
 
The distance between the objects you want to pull focus between, ideally, should be greater than the distance from the lens to the closer of the two objects. For instance, an object 5' away and another object 20' away. Effect diminishes if both objects are 20 and 30 feet away.
