One thing to keep in mind if you want to try with the i1pro2, it has to be on its plate when you select it, and you have to press the button right away to do a white calibration. Otherwise, the software will tell you it can't find the meter.That's not ideal, it should first detect the meter, and then ask for a white calibration.Also, with the i1pro2 about two feet from the screen and reading 65nits, it was not possible to get the meter within the box. I'll try with my HDR calibration, I might get better results with the iris fully open.
It's a shame they've not improved the meter setup for the i1pro2 when moving to V11. It was all a bit "afterthought" in its implementation in V10.It seems V11 behaves in the same ways with the i1pro2 as V10. By far the most annoying behaviour for me is that you have to re-connect and re-calibrate the meter every time you go into the calibration mode, so if you've just done one calibration you have to get it back down off the tripod, put in back on the plate, and then back on the tripod again. If you're dextrous you can just about hold the meter onto the calibration tile with the tile rotated a few degrees without taking it off the tripod.I think the positioning box for the i1pro2 readings from screen is completely bogus and serves no purpose. Measuring off screen without the diffuser you can't change the position of the meter within the box on screen - as you bring the meter closer to the screen it measures a smaller area of the screen, cancelling each other out. Any change in the position witnessed within JVC autocal will just be due to the meter reading either a different area of the screen with more or less variation across it, or measuring the screen at a slightly different angle. The only way to significantly affect the on screen "position" of the meter when facing the screen is just increase the light output somehow, which is kind of pointless as you're wanting to calibrate at a given iris setting and into a particular "slot" in the projector.@Dominic Chan had a cute way of getting higher off screen readings by measuring using the i1pro(2)(?) off a white surface that was closer to the projector. That way the projector is set up "correctly", you're just moving the screen closer to concentrate the light. You'd really want that surface to be a screen sample if possible; though Dominic was using it mostly to overcome his lack of a diffuser for gamma measurements so I think he was just using any white surface.Having said that, for just the colour autocal I'm not totally sure why it would make much difference. Even at 65 nits peak white you should get quite reasonable quality colour measures even for blue, so it might point more towards the maths in either autocal or the projector not being great, or the projector not being linear enough for the simple algorithms the colour autocal uses to work well.
Regarding the need to recalibrate the i1pro before every calibration (I agree it's cumbersome as it is implemented), I use the following trick (undocumented as my list is already too long, but I'll add it if you find it useful): I keep the i1pro on its tripod in position, I start Teamviewer on my iPad so as not to have to move my calibration laptop, and with one hand I hold the calibration tile against the i1pro2, with the other I select the i1pro2 on the autocal (on the iPad) and quickly press the measuring button. That way, at least I don't have to move the i1pro off its tripod and lose all the profiles etc. I use Teamviewer as well to monitor progress and control the software distantly. As long as a meter action isn't needed, that allows me to get more sunlight and watch less patterns
That's what I meant by if you're dextrous; it sounds like you use the same approach I do when I've used the I1pro2 in that way. It's a bit of a handful (at least for me with my micro-hands lol) to to grip the tile onto the meter (plus for this setup my meter is often up in the air fairly high up), and I'm always just a little bit sceptical that it is a particularly good approach (though I do it myself) because the i1pro2 does to wavelength calibration off the tile using the green LED, there is both a chance of the tile not being completely flat, and also some scope for light from the PJ to leak around as the calibration happens.If the JVC autocal utility worked a bit more sensibly - just doing one calibration on the meter on demand - it wouldn't be so tempting to take these short cuts, it's the case of a bad workflow promoting slightly risky behaviour. When I'm trying to do stuff properly in other SW I usually shove the meter and tile under a black piece of cloth for the calibration measure, or at least press the hide button on the PJ to make the room darker.
@Bobof: I've added the i1pro2 improvements request at the end of the second section in the feedback to JVC/suggested improvements list. Please let me know if that suits you.Once we've gathered enough feedback from everyone, I plan to ask Mike to forward this list to JVC.
...When I switched the PJ back on, the iris made a weird noise (hopefully a one-off) and I now have the new f/w and Autocal installed (see screenshots).
Manni,For color calibration, is it more accurate the i1pro2 than the spyder 5?
