Hey anyone there ?

Hey <Bertl> , can you just review my proposal . I did few changes and wanted to get it reviewed

08:51
Bertl
looks good, but you probably want one of folks working on OpenCine to check it
08:52
Roopal08
Yeah. If anyone could go through it before deadline . Then it would be great
08:59
Bertl
you are in a half hour timezone ... how much fun is that?
09:09
Roopal08
Doesn't affect much. :)

se6astian
so regarding olpf its close to 50/50...
16:08
se6astian
that doesnt really give us a clear guidance :)
16:14
intracube
I guess 46% of people don't want to film brick walls or mesh fences ;)
16:15
intracube
se6astian: have you identified a source for the plain UV/IR filter?
16:17
comradekingu
Likely "how important is being able to remove LP filter to you" will also give interesting results
16:18

16:21

I guess the shifting backfocus issue would be resolved if you could get a combined OLPF+UV/IR of a common thickness
16:22
intracube
then it could be hot-swapped on location with a plain UV/IR filter
16:22
intracube
assuming they have the same refractive index?
16:25
intracube
the poll was still useful
16:41
Bertl
off for a nap ... bbl

(6:21:31 PM) intracube: I guess the shifting backfocus issue would be resolved if you could get a combined OLPF+UV/IR of a common thickness <- correct, if the density of the glass is the same
17:48
se6astian
density -> refractive index
17:48
intracube
yep

OLPF/UV manufacturers: http://www.made-in-china.com/manufacturers/olpf.html
18:07
intracube
some products there look promising

there is also http://www.optics-online.com/lpf.asp
18:18
se6astian
quality and price would need to be evaluated
18:25

intracube
it could also affect the sensor calibration
18:41
intracube
http://www.optics-online.com/OOL/pics/IRCcurve40.gif
18:43
intracube
the reflective IR filters (IRC31/41) have a sharper cut-off
18:43
intracube
absorptive looks like it would skew the colours
18:51
intracube
$50 seems very cheap
18:52
se6astian
I would also assume it affects colors
18:52
se6astian
50$ for which diameter
18:53
se6astian
gotta go
18:53
se6astian
pick and place day ends :)
18:53
intracube
:)
18:54
intracube
10x9mm
18:54
se6astian
thats very expensive
18:54
intracube
probably for cctv or similar
18:54
intracube
gets confused between several brower tabs
18:54
se6astian
the 72mm diameter uv/ir cut off filter we currently use is high end and around 60â¬
18:55
intracube
this is for OLPF + IR though
18:55
se6astian
cut that into 10x9 pieces and calculate the price :)
18:55
se6astian
ah
18:55
intracube
http://www.optics-online.com/lpf.asp
18:55
se6astian
then the price is ok
18:55
intracube
also highly likely there will be different grades
18:55
se6astian
300⬠for apsc size is normal
18:55
se6astian
which is around 6x this 10x9
18:55
intracube
everything from standard def cctv up to 4K cinema grade
18:57
se6astian
the olpf needs to match the pixel size
18:57
se6astian
anytway
18:57
se6astian
gotta go
