Expoamigo White Balance Filter Review

[azul123]

I tested by setting manual white balance twice - once with the blue line outside of the circle, and the other, inside. There was no effect with the blue line outside of the circle. In the second case (blue line inside the circle), the pictures were distinctly warmer. Actually, they were much warmer than desired. Instead, a small spot of blue produced just enough warmth.

Thanks for the info on this, I have not played with this WB gadget yet... still unopened, was thinking of trying it soon. May I know the small spot that you placed would that be dead centre on the Expoamigo?

No need to be dead centre. You can place the dot anywhere on the Expoamigo. When using it just be sure that the dot is anywhere inside the partial metering circle in your viewfinder.

Just like what I wanted to say, thanks man.
It's not the position that matters, but it's the proportion of blue area for sampling that matter.

Update on the Expoamingo Filter,

It cannot be used on my Sigma F2.8 24-70 EX lens. It's just unable to get a Custom WB. BTW i'm using a D70.
One thing i notice , On my kit lens i can see the Beads shape and i can get a Custom White Balance , but on the Sigma i can't see the shape though it is a big blur.

Hi, please try if the following works,
change to iso 400 and use maximum or minimum aparture to adjust the white balance.

this might sound stupid... but when placeed against the lens, should the flat surface be facing the lens or the rough surface? And must it be directly against the lens or we can hold it further away?

Not stupid at all, in fact, a lot asked the same question, normally we use the flat surface against the lens but some Canon users told me the bead side facing the lens works great too. So depends on your camera make. And it's placed against the lens not further away.

About the marker used to draw on the expoamigo, is it permanent marker kind? or white board kind? any brand and model to recommend?

It's permanent kind, I am using Zebra blue marker with two tips, one broad one thin.

just got my expoamigo. Here is my user report.

I get far better results by pointing at the light source. Anyway, common sense should tell you that for WB filter to work it should be pointed at the light source as and reflected light from the subject would have "colored" the light. Unless you idea is to force your subject to be closer to grey color then you calibrate towards the subject.

Anyway, I noticed a blue tinge to the expoamigo cal shots. The expoamigo gets you 90% there but still not good enough I feel. But it is very cheap so not too bad. if I buy expodisc and get the same results, that will suck.

Personally I feel that drawing a blue dot to compensate is a VERY bad idea. That just makes your calibration unrepeatable as without a screw thread, the position of the blue dot is different every calibration....

my newbie 2 cents. Did anyone try the WB filter SLCC, zerocs is selling? or done a comparison between the three filters available in singapore? expoamigo, zerocs, expodisc?

Another issue with the expoamigo is that you cannot screw on so one hand must hold filter and it is tough to trigger my one touch WB.

haha, i'm interested to know too. Have been thinking of a WB filter.
