i don't know much about video, but i've heard of a 180degree rule, but it had nothing to do with shutter speed.

See https://en.wikipedia.org/wiki/Shutter_speed#Cinematographic_shutter_formula, it comes from the mechanical rotary shutter traditional video cameras have used. I suppose it's not really called the 180-degree rule, it's just that's what stuck with me in my head from the traditional 24fps @1/48s shutter speed.

I'm a video noob. And I'm curious... What's wrong with shooting at 60fps?

I understand how ND filters work with aperture, but if slo-mo is what you want, why would you shoot at 30fps with an ND filter, rather than 60fps without one?

Nothing wrong with shooting at 60fps, in fact it's often used so that in post-production you cut the output framerate in half to get 30fps output so you double the time it takes, which give slow-motion.

Beyond that, the general rule in video is to get a 180-degree shutter which gives a nice, smooth look you shoot at 1/(shutter speed * 2). So for 30fps you shoot with a shutter of 1/60, and with 60fps you shoot at 1/120, or as close to that as you can get (so 1/125 on most DSLRs). So the only way to control exposure is with ISO or aperture, or to use ND filters to cut the amount of light. Since the OP wanted a very shallow DoF he needed to use some ND filters to cut the light to allow his aperture to be wider since he undoubtedly had his ISO set very low (100-200). Since he had no ND filters, he had to raise the shutter speed significantly. This can give video a more stilted look, since every frame is much 'sharper' and there won't be any motion blur like you can sometimes get with the slower shutter speeds.

Quite nice, and a very good job keeping the focus where you wanted it at f/2. What supports/focus puller/etc did you use?

what makes you think the canon broke the card?

counterfeit sandisk cards (approximately one third are fake says sandisk) show this behavior quite often.

The card was bought from an "authorised store"  and was pretty fast. I do not think it was a counterfeit one.

And I think that camera broke the card because did the same think when tried with another card.

Perhaps time to contact Canon Support? If you have another camera you can take a video with, maybe take a video and show exactly what you are doing and the way in which are doing it.

Sometimes I run out of disk space. Even having a ton of hard drives, shooting RAW doesn't always make sense. If I'm going to print something, then always RAW. Otherwise, M JPG has worked well in many situations (candids, landscape).

I think M RAW is actually a pretty good compromise, and you're getting noise reduced via interpolation.

Sometimes, I make so many photographs and can get so sidetracked by manual RAW conversion that shooting JPG speeds up my ability to catalog and review everything.

Actually, you can get that noise reduction via interpolation from the full raw, just export as a smaller JPG.

Definitely takes a lot more space, and takes longer to sort through at times because of waiting for LR4 to prepare the preview images on import, even the standard previews. But, for me, that's why I built a 8TB RAIDZ NAS where I keep everything and backup to CrashPlan from that.

The entry level Manfrottos are very good for the money. They're quite sturdy and well built, though a bit heavy (around $120). Top it off with a Benro B1 off of ebay for around $95 and you will have solid support that will last for a little over $200...

That looks like a pretty good combo for the price.

I agree it somewhat depends on your needs and skills at getting the right exposure. However, there are some circumstances where it really does make a big difference. Such as the shoot I'm doing tonight, which is an inside dance/burlesque performance which will undoubtedly have some poor to really bad lighting. So RAW lets me push the exposure a bit and fix the white balance which is undoubtedly screwed up because multiple lights with different gels on them, and use what I believe is superior LR4 noise reduction as opposed to camera NR. I'll try out the Nik Dfine2 that I go through the Google Nik Collection deal.

So, long way of saying, I pretty much always shoot full-sized RAW with long exposure NR (which does darkslide exposure to subtract noise), and otherwise low or no in camera NR. And then after I sort through what I'm keeping, I delete the rest generally to save on storage space.



There was a period of time when I made myself shoot JPEG only because I thought to myself an excellent photographer must be able to get composition, exposure, color balance, and everything else perfect on the spot. The I was introduced to what LR4 could do and I became a convert to RAW shooting.

The reason I asked about size is because large RAW is just too big for storage. I don't know if small is high enough for printing wedding photo sized canvas, which I think is the largest print size I would ever need.

I heard that LR DNG format is smaller than CR2. I never convert format when I import. And I don't know if I should.

Hmm...well, I'd say it depends on the resolution of your S/M/Full RAW sizes. In general, S probably will give you most smaller print sizes. Take the resolution and divide by 300dpi to get how big a high quality print you can make.

Personally, the other use for full size RAW is if you find you need to crop to get framing/fix horizon/etc the extra resolution can be helpful. Then of course output at the size you need. You're right though, full sized RAW is very big, however my solution is to delete the ones that I decide are crap or aren't good enough to use. And then store them all on my ZFS NAS with CrashPlan backup.

3 sticks, hot glue, bailing wire, and lots and lots of duct tape.

Alternatively, what about something like a gorillapod? You know, the ones that wrap around and hold onto existing uprights like a tree or pole or something? Smallish, portable, and relatively inexpensive compared to good tripods.

If you're actually going to be in the middle of a flat area with nothing to use the gorillapod on, get some of the cheapest tripods that'll hold the camera + lens, and start saving up. I'd recommend $400+ and get a quality tripod, although not top of the line. Trust me, I went from ok second hand, to heavy and sturdy (but heavy!) second hand, to a very nice, new, mid end Benro carbon fiber. It might take some time to save up. Go do more chores, or take some artistic shots of local landmarks and sample prints and setup at your local farmers market and take orders or something.

Third Party Manufacturers / Re: Introducing the MōVI Stabilizer

Looks pretty good...but will these other options A) hold up to 15 pounds with the same stability, and B) also allow for remote operator to pan/tilt with a well integrated system?

Home-built or low cost tools are great, and definitely should be encouraged and often turn out great work, but I hesitate to say they are usable for the majority of film makers, especially not for ones with any serious amount of budget. They will be attracted, in general, to very well made, very well supported, and known and trusted tools. The Movi meets the first one, so far seems like it will meet the second, and with Vincent Laforet endorsing it, it has a very great start on the last point.

agree, DIY solutions lack the level of support I would expect from a solution that costs 15k. but its certainly worth a look for indie film makers on a tight budget because you can get the same results for a fraction of the costs. I wouldn't be suprised if this gimbal was actually inspired by the recent developments by DIY projects such as the one from Alex Mos.

Could be, or maybe the DIY was inspired by commercial designs which include the hover copter that those guys have. But I agree, it's something that an indie film maker on a very limited budget might try, and probably would still get good results even if it's not as refined and doesn't quite have all of the same capabilities or as refined as Movi.

Lenses / Re: EF 300mm 2.8 IS - Anybody seen anything like this?
« on: April 08, 2013, 08:52:34 PM »
I personally haven't had that, but it certainly looks like some of the samples I've seen elsewhere for a mis-aligned lens element.

TDP mentions servo issues with the new Tamron 24-70, seems to be a common issue with 3rd party lenses.  My 35L does very well in servo mode, old though the design is...

Agreed, I have seen some issues on the Tamron 24-70 in AI-Servo on my 5d3. At least under very low lighting. It works, it just doesn't really always work well. Especially if it has to go from near to far or far to near focus at the start, although I suspect that's just a difficult use case on that along with low lighting for any camera/lens to handle.

I have the Benro C-0681 travel tripod, and love it. Folds up pretty small, lightweight, and can hold a pretty decent load. Got it back in December, and haven't had any problems with it at all. Except I'm not getting as much exercise anymore, with it being so light and fairly compact.

i do aerial filming and we recently already got this thechnology for gopro sized cameras, check this ultimate test: https://vimeo.com/60977570#at=0

a version for DSLRs is already being developed and should be out soon. The controller and IMU is developed by Alex Mos: http://www.simplebgc.com/ and costs no more than 110Euros, e.g. at http://flyduino.net/Alex-Mos-Brushless-Gimbal-BLG

I expect that the DSLR gimbal will not be more than $1500  8)


here is another one where two different controllers are tested: https://www.youtube.com/watch?v=c8iwlrilpHQ - seems that these things are not that complicated, just someone had to have the idea ;)

Welcome to the "Apple rules everything" world. There are plenty of people in it. For the rest of us...well...we can complain and say we won't give them our money for it. About all we can do. Or just give in and buy one, which I won't do.
