Chronos User Discussion / Re: Lens/Camera protection
« on: April 28, 2018, 11:29:58 PM »
I shoot lot through polycarbonate and when it's new it doesn't effect the picture quality but it's quite soft material and scratches easily. So if you have to film lot through same shield it's good idea to make small window and replaceable smaller shield for that so you don't need to change hole big and expensive blast shield when it gets some scratches.

But if you have only bb's flying and maybe bouncing back I would fit just protective filter for the lens. The uv-filters are one option but there is more durable filters that are meant to be used as an shield's. And make sure that the camera doesn't fall from the hits and you should be ok :D My chronos has been hit quite many times with various shrapnel and it works just fine :D

We were filming somethings couple weeks ago with big and expensive phantom camera but the chronos footage turned out also surprisingly good on this 5 meter long stick of dynamite video https://youtu.be/ThLtMhiak-Q

The chronos footage starts on 8:20

I was wondering, What model phantom were you filming with? I recall you saying "the best one" Would that be a v2512?

Cheers,

Yep it was v2512 with fast option and larges memory. Only problem was the finnish weather and short day :D But I got funding for the camera with really short notice and it's just couple days in country when you order that so you get the weather that happens to be on filming day. We actually filmed this week also one day with the thing since one of my friends customer needed 80 000 fps camera so they had to rent that one again and they needed it only for one day and I got the second day really cheap since minium rent period is two days.

This time we did some DIY shaped charges and 70 litre gasoline bomb :D The shaped charges looked quite nice with the phantom but I got also really nice clip with the chronos from gasoline bomb. I am publishing that video tommorow and I can add link here when it's out.

But in generally I think that the v2512 phantom and chronos are good match for youtube videos. You can take clip from small details with really high frame rate with the phantom and then wider shot with chronos with speed aronud 1000-3000fps. I am probably filming next time when it's bit more light or if I get somebody else to pay for the phantom.

I think this is also really nice shot https://youtu.be/HcTRapGoHK8?t=3m43s
It's the same reaction filmed with two chronos cameras, color version and black and white. I had color version recording 500fps to get more light and black and white little bit faster. I think I could do better now since this was my first video with the black and white model and I didn't know how to exactly set it up to get best possible picture.

At least with the Phantom cameras the limit when export difficulties start is 1 000 000 fps

We film usually couple videos per week with the Chronos but I really like this video that we filmed couple days ago

We filled up some "balloons" with non newtonian fluid and shot them with the crossbow. I think I used something like 3000 fps on most of the shots.

I think I test with 3d-printed spacers under the lens that I have.

Then I have thought about testing with some stupid long lenses also. My dad has an old mirror telephoto lens for some film camera so using it with some adapter and small sensor of chronos would probably get stupid amount of zoom :D I think it's something like bit over 1000 mm for normal sized film. I will make video about the thing when I get the adapter for that purpose.

Chronos User Discussion / Macro lens suggestions
« on: June 15, 2017, 01:29:30 AM »
I have the general purpose 12.5-75mm lens for my Chronos and it's great for most of things that I film but I think I could use macro lens for some projects also. I think it would be good to have as short minimum focusing length since I am working sometimes quite small rooms so filming far away with lens that just zooms in with the small sensor isn't good option.
