zooming

basflt

thats the term for it
some people dont like it , i do
been a while since i last tried
here a recent one

I actually like it. It doesn't make me dizzy, but follows the rays of the light. Good work

basflt

thanks Mary , appreciated

Doesn't looked zoomed at all save for the suns rays coming through the branches.
The result you have here is super nice
Is what we are seeing here an effect done in camera and then PP enhanced for final appeal?

thanks for compliment

i recon you dont know about the technique ?

its simple

you need a zoomlens & tripod

shutter at 1 or 2 seconds in manual mode
zoom in
while clicking zoom out

thats it
rest is indeed PP

result vary with the speed you rotate zoomring

That 2nd shot is equally nice. Looks pretty sweet.
Appreciate your laying out how its done. I asked the question cause I would have expected to see more zoom stretch to the details of the darker tree such as the branches and small leafs. Those portions don't appear visibly stretched much as does the all the brighter light areas everywhere else. One can easily see the rotation duration time of the manual zoom while the shutter was open. Its just curious to me that the dark portions don't appear "zoomed" while the light areas easily show it. I've gone back and looked at the few zooms that I've done to see if the same thing happened and the answer out of mine was both yes and no. Might have to throw some study time at that to satisfy what I'm missing about
what to expect with light and dark while zooming. Also it is very possible to zoom without a tripod. Just thought I'd throw that out there. Some tricky but doable.

i see what you mean
it surprises me too

my guess , for what its worth
its because these areas are dark > not exposed to sensor
only light is recognized by the sensor
also time of exposure seem to matter

looking forward to your "study"results , if you found time for it

Nice shot! You used the effect to enhance the rays of sun... brilliant!

Here's the deal with the zooming effects: remember, sensors operate like film. Light is burned onto the sensor when the shutter is open. So in the first image, it looks like you zoomed quickly, and then stopped zooming for the rest of the exposure. Once you stopped zooming, the focused light had longer to burn onto the sensor. It's more defined. The light that fell onto the sensor while zooming, is (halfway) transparent, because it had so little time to reach the sensor before the light was altered by the zooming.

The longer you leave the zoom ring in one spot, the more opaque the subject will be. Try zooming for the full exposure, not stopping at all. It will be a lot more blurred, similar to #2.

Also, remember it's light that's falling onto the sensor. That dark tree is, well, not light, if you will. Light areas will burn onto the sensor more readily, because, well, they are light. The tree doesn't contain as much light, so it will take longer to burn onto the sensor.

thanks very much
both for compliment & explanation

biggest problem i encounter =
facing towards the sun ;
with aperture at its narrowest and ISO 100 , i cant get shutter-speed slow enough

ThatCanonGuy

Yeah, I have that problem too. Even at ISO 50, I usually can't get it to last even 1 second. Sometimes I use a wired remote release, and start zooming before I open the shutter.

basflt

3seconds - f2,8 - ISO100

ThatCanonGuy

That one is cool - neat processing

basflt

thanks ,
but not processed
pic is as shot
nothing changed or whatever

ThatCanonGuy

Well, neat light then
