I'd like a collapsible white balance card.
Lastolite is my first point of reference, but I'm not clear on whether 'white reflectors' are suitable, as they errr 'reflect'.
The 30cm size would be handy - so around 4 inch diameter to put in pocket.

They do the tribalance grey cards for white balance, but have no experience/understanding of setting a camera pointed to 3 shades of grey??

Any other makes I should be looking at?

You can white balance on anything from pure white to jet black, all you need is the absence of colour. So the best thing I find is a Kodak grey card as this will sort exposure queries at the same time. Mine's A4, but of course you can cut it into smaller pieces should you want to.

Thanks Tom.
I can understand white/grey both being acceptable as the software will just say 'do rgb values equal each other' and adjust accordingly.
For the tribalance, I'm guessing you have to zoom on to it so one colour fills frame - otherwise the software will have to be a little bit more clever in recognising non-adjacent pixel areas.

Another vote for the warmcards - I got a set and they're great, especially for winter weddings!

The Z1's assign buttons are good for this, as they can be set up to warm or cool the locked in w/bal by small steps.

The warmcards are good, they get my vote. But if all you want to do is to white balance, then Tom's right, choose something neautral and use it. But, beware of using ordinary white paper, it's fine in doors under tungsten lighting, but under daylight or fluorescents it's distinctly blue because it contains the "optical brighteners" that make it look "really white", photocopy and printing paper is really bad for this. If you want a cheap source of paper for white balancing, use fresh newsprint (not the FT), it contains no brighteners, but it does age quickly soyou need to use fresh paper (i.e. not more than a week old).

Get my test cards document, and cards for 625, 525, 720 and 1080. Thanks to Gavin Gration for hosting them.
Camera settings documents are held by Daniel Browning and at the EBU
My book, 'Circles of Confusion' is available here.
Also EBU Tech.3335 tells how to test cameras, and R.118 tells how to use the results.

Thank-you for all the feedbck.
I am not a fan of buying things on $ sites and £8 delivery for UK retailers of £15 reflector seems steep, so I'll see what Jessops have with above comments in mind.
Last time I asked for a white balance card in Jessops I received a vacant response.
Quite surprising since digital stills cameras also employ white balance these days.

Tom - Haven't used the assign buttons for this, but found the A/B settings handy for inside/outside setting up when flitting back and to.

Yes, the A/B w/bal settings are good if you've got the time and inclination to do tests and lock in those readings, then remember which is which. The beauty of using the assign buttons is that you have a v'finder readout of how far you've strayed (+ or -) from the preset daylight setting.

I can see that a display for difference to norm is useful, but unless I'm plugged into a larger monitor I personally place more confidence in the setting for the white balance card and doing any required tweaking in post-production, than using my judgement to +- with reliance on the small display.

Dave, the warmcards are very good in my experience. you get a larger card and a small set for putting around your neck (comes with a strap).

Got mine from Videogear

Thank-you for the link Neil.
My preference is for straight white and tweak in post-production, so don't think I'll go for wanrer cards, but they are within driving distance, so worth a visit/browse.

Am I correct in assuming that no one uses the white card that comes with the Z1E?

Nope, I got a card (plastic) with my Z1E Might have been a freebie from the supplier?

Call me mean if you like BUT I have used for more years than I can remember a white (usually slightly grubby) handkerchief.
I know about the brighteners in washing powder etc. but it is the best portable white in practice.

I pondered this a couple of weeks back, then dismissed it, for reason I can't remember.
Provided it's thick (or folded to be non translucent) it must be the best solution?
and not widely advertised as there is no expensive mark up for retailers..
though may not impress client if he sees you with a 'stressed' variant.:eek:
