non Pan-Focus image

[salt-sg]

The only dissatisfaction which I have to Super8 is that it have too deep depth of field.
I want to shoot the blurred background with 6-25mm zoom range.
Although I understands that it is difficult one physically,
does someone know the magic which realizes it?

shoot wide open; shoot with the long part of the zoom in this case 25mm). shoot in lower light to let the lens to open up.

Use ND filters to drop f stop in bright light situations. Just make sure they are of high quality. You dont want to compromise color and contrast.

Thank you, rollemfilm & crimsonson.

I guess that we can get only a little blurred background, even if we use f0.95 at least at 25mm.

Do I must use a larger format?

a 25 mm lens opened up to f/1 and focused on 15 feet will give you a dof from 13'6 to 16'11. anything beyond 30 feet or so will be very blurred, the way i believe you want it to be. field of view is about 4x3 feet at that distance, which should be a nice medium shot. good luck.

Thank you, mattias.
It is almost same image as one that I want to shoot.
I will try to shoot it.( and to get 25mmf0.95.)

one more thing: one thing that really helps if you need a blurred background is to use a high contrast one. a typical landscape will just look out of focus, while distant street lights, reflections in water, dark trees and such will look blurred in a more obvious way.

mattias:

I understood that you are talking about total coordination that I must care for.
I agree with it.

By the way, I remembered that at one time I built a very large background panel which blurred beforehand, in order to get a very blurred image which is not physically possible.
It was for TV commercial, and was shot with 35mm-moviecamera and telephotolens.
Such an effort was made even 35mm, to get blurred B.G!!

It was a very interesting case for me.

I found a interesting equipment.

it's too cool but too expensive, and only for DV.
