reverse engineer this look...

Hey there Guys,

How many of you have seen this body of work:

http://blog.chasejarvi​s.com …-work-celebrity-maps.html

It is by Chase Jarvis (much respect) and i am having a hell of a time figuring how he got the sensor bloom to look like that!?!?

I have tried similair setups, but have failed in creating the horizontal and vertical bands that connect the lights. All i get with my attempts is plain old lens flare look.

It has been suggested that this is something that can only happen in older generation CMOS's, and i have thought that maybe it has something to do with the nature and number of fins in the lens's aperature.

Any thoughts?

If you look closely at the images, you will see three Pro7 flash heads on each light stand. I do not believe that he used any reflectors on the heads just pointed right back at the camera. I didn't look to see if the subject was lit from the front but a V flat will bounce plenty of light back at her.

You need to figure out how to create sensor bloom. You can make it happen in camera phones and cheap digital cameras but I've never seen it happen on a modern DSLR but there's probably a way to force it to happen.

Here's a "normal "shot of a flash at f/16.

Ask him!

Seriously - Chase is VERY good at helping other people out. Don't say you want to replicate his shot or his style, but that you want that bloom effect for something else -- he will respond.

i've seen blooming like that when pointing a 50mw laser at a CCD chip... - wierd vertical stripes too - and it takes a second for the effect to dissapate - so not something to try at home

as for the effect here- would a cheap chinese UV filter have that effect? (diffision of v-bright areas through the substrates?)

or maybe the whole thing is shot through a glass window? (that's having the same effect)

From the comments on Chase's blog --- Chase said:

the bloom is caused by some problems in the phase one back... here's a post about it

Sensor designs differ, CMOS doesn't read out the same way as a CCD and blooming like that is largely dependent on the CCD readout structure.

You might be able to reproduce something like with something blocking part of the light source. Get something that will block light. Cut a circle (not to big) in the center and then cut out a plus sign over the circle. Maybe that will work?

I have seen that kind of blooming on my old Nikon D50, whenever a highly overexposed light source was hitting the sensor directly, BAM bloom. the D70 and D70s exhibited the same behavior
