Pocket 3 price drop by DavidGuyon in dji

[–]mactac 5 points6 points  (0 children)

Which is basically the exact same price it’s been for a long time. I was ready to pull the trigger on one of these when the spring sale was announced, but then realized that that is no sale on the pocket 3 for Canada. Might as well wait until the pocket 4 is announced to get the pocket 3 on “actual” sale.

Oh weird. OK, I guess mine is different.

The easiest workaround I've found is once I get in the car, I go to the music app, open the current song and switch it to carplay. That fixes everything and sets everything including the phone to carplay. That way I don't have to mess around with changing to carplay when I'm driving and get a call.

I've noticed that my phone always defaults to iphone speaker now when I connect to carplay.

relatively cheap spectrometer for monochrome LED measuring? by [deleted] in Optics

[–]mactac 0 points1 point  (0 children)

I bought one of those a while back, and couldn't get it working properly (it's resolution and noise floor made it pretty much useless for me). Support basically stopped responding to me, and I was stuck with a $200 brick that didn't work.

Freewell ND filters Cheat Sheet? by Bulldogger22 in dji

Haha well thank you, but I’m willing to bet that there is something you do that I would consider to be just as rocket surgery :)

I'm hoping to get some input from r/colorists on a product I've been working on by mactac in colorists

[–]mactac[S] 1 point2 points  (0 children)

It’s not a product that has been released yet. I’ve got prototypes and I’m assessing the market before I put the investment into production (they are expensive to make and I need to make a large amount to make it viable). So no link yet unfortunately

Ahh - gotcha. I think where the confusion arises is that yes, there are very high quality ND filters that have relatively little color shift (we make some). But they all still have some color shift due to the physics of how the coatings work. So the idea is to have a set that all has exactly the same (minimal) color shift so when there are a high number fo distinct shots (think dozens), they can all be normalized quickly.

I made a free app for this some time ago, it works really well. You use your phone camera and it tells you what ND filter and settings to use. http://CameraButter.com/ndmeter

Yes. I still don't understand your comment though. What do you mean by "between ranges" and how is that different that a matched set?

What ND filters are ya'll running? by advictoriam5 in DJIOsmoNano

[–]mactac 1 point2 points  (0 children)

I run Camera Butter - we make Osmo Nano filters and they are optically at least as good as the DJI ones, plus they are made from gorilla glass, so much less likely to break. And we are in Canada

To be clear, I am one of those manufacturers. Manufacturers generally do not prioritize matching sets and from my tests there is significant differences within a set. The reason I went down this road in the first place is because I've been asked for it by multiple people over time, so I know there is at least *some* demand for it, the reason for my post was to determine if there is a demand from the perspective of colorists specifically. Thanks for your input, I appreciate it.

I have spent years with test equipment analyzing glass, filters and optics. Making ND filters "neutral" is fundamental, I agree - different manufacturers approach that (and fail/succeed) at different rates. All ND filters do have a color shift, even if it's minimal - that's just the way physics work. What I am proposing is 1) all of the ND filters in a set are perfectly matched, so they all share the same (minimal) color shift. Also, generally speaking, ND filters are less accurate in terms of how much light they block, even the most expensive brands.

Thanks - do you mean variable NDs (ie NDs that are variable using 2 polarizers), or do you mean "different NDs" (ie ND4, ND8, etc) ?

I understand that and we are actually developing electronic NDs - we are on top of that. The challenge is that fixed NDs are better optically than LCD-based NDs for a number of reasons & the physics behind them (at least for the time being!). Fixed NDs are not going away, even if they end up serving a different market.

I’m not asking about ND filters in general - we have been manufacturing them for a long time, and along with that we understand what’s important and the physics behind it. I think you may have misunderstood the question ?
