thanks to all the big brains
 
i am very happy also, and am using this preset pretty much all the time.
i'm very glad there is so much knowledge available here, and shared so graciously.
If left to my own devices, i'd still think that 'frame rate' meant the amount of innocent people in jail...

I just finished shooting a project with the following pre-sets and now starting to tweak a bit. I was attempting to match the DVX and then made some adjustments of my own. I've noticed my red are slightly pink and I am not picking up the blacks (more often than not they just dont register). I shoot a lot of documentary footage in low light and would like to adjust for that.

does anyone have suggestions?

Blue cast at TC
 
I want to refresh this topic. I'm new owner of XH A1s. I also notice blue cast at TrueColour preset. Here are my shots with fabric preset and TC.

What to do with it?

Artur,

Did you manually white balance before shooting?

I set manually, automatically and pre-defined. I shoot in daylight and tungsten. Always the same: blue cast. I can post other shots if needed.
Sorry, if my english is poor.

Artur,

Your english is fine....do not worry.(Nawalaneic was my mother's last name, but I know very little polish)

Did you also notice the blue when you manually white-balance? After white balance..white should be white. You have a picture with white curtains that look blue. If you properly white balanced, the curtains should be white. Yes?

I use truecolor preset and do not see the blue.....maybe I should look harder at my work.

Hi,
Thanks for reply. Images above are auto WB. Curtains and window are white. Here are some shots took this evening at tungsten light. Manually white balanced.

Last name your mother was probably Nawalaniec. It's typical polish name :-)

Edit: I noticed that using Auto level function in my PhotoImpactXL produce almost white balancing images. It means nothing of course.

Artur,

I will test and upload pics. I will manully white balance.

Artur,

Thank you for correcting my spelling. I believe Nawalaniec means "Baker's son"

Here is a comparison of "no preset"(LEFT) and "truecolor"(RIGHT). The white board is a painter's canves that I used to manully white balance. I will let you look and see if the blue is there. (NOTE: I had to increase the db setting on truecolor....low lighting in the room....it made the pic a bit lighter)

My white balance procedure:
1. Select a custom preset; and VERIFY custom preset is "ON".
2. Zoom in on white board. (I do not focus)
3. Press white balance button until it stops blinking.

If you don't see the blue in my pics, you might want to check the trucolor set up to make sure all values are correct in the setup.

Hope this helps, Artur.

Regards,
Michael

Hello Michael,

Thanks for help. I'm at work in office now and will test it at home later.

My procedure:
1. manually white balance on white page without any preset
2. turn preset on
3. shot
Do I something wrong? Does any preset influent on white balance? I thought every preset manages an image AFTER white balancing.

I see slight blue cast on your Truecolor's shot. Take it to your graphic aplication and test it by eyedropper. I will do it too.
My shots has been taken without gain.
And last but not least: Nawalaniec doesn't mean "baker's son" :-) It's difficult to explain what it means. This word probably origins from verb "nawalać" which has many meanings.
Sorry, I think polish and write english - I hope you won't cry of angry or laugh :-)
BTW: my last name "Śmiech" means "laughter".

Michael Hutson March 25th, 2009 06:18 AM

Artur,
Change your procedure.

1.TURN ON PRESET
2.WHITE BALANCE ....I think that is your problem.
3.SHOOT

Thanks, Michael!
It's 3 p.m. I finished work and go home to test it. I do as you wrote.

It's 6 p.m. I'm at home and did your procedure. It's all the same. I will try to modificate this preset. Did you noticed that black parts are black and only white tend to blue? Upload images, put them into Photoshop (or similar) and use eyedropper.

One thing to be aware of is that auto-WB and manual temperature dial-in can produce very different results. WB definitely adjusts more than the single color temp.

On that note, I get a blue cast when using WB with truecolor, but not when manually dialing in the temperature.
