60D over exposed in sunlight - how do I control?
« on: June 08, 2013, 07:56:08 PM »
I have a Canon 60D + 50mm F1.8 lens

It's on shutter speed of 50, FPS of 24 and aperture of 1.8 (what I want) - I have on manual exposure
I tested yesterday. All fine

I shoot today. Damn!!
Over exposed!!
There wasn't a control for the exposure - or at least I couldn't find it

I put on auto exposure - all fine now and beautiful video
BUT I wanted the blurred background look
The aperture was pushed up to a higher value and no longer changeable

What am I doing wrong?
(This was actually my first attempt to do video outside!!)

Thanks


Omar

Turn down the light intensity. Do you have a dimmer?

how do i turn down?
what control?

i couldn't dim the sun - it's powers where too great for me. (joke)
i take it u r talking about something else
let me know what it is

still a relative complete newbie - so ur advice is greatly appreciated

thanks

"Dim the sun" = use a neutral density filter.  If you're already at 100 ISO and like your other settings, that's your easiest option that I know of.  Moving to (or creating) shade, or shooting when there is less sun are other options, but it sounds like that's not what you're looking for.

+1, use ND if it's too bright. Use spot metering on your subject to make sure that your subject is properly exposed.   This is very important since exposure isn't 100% correct most of the time for high contrast scenes.  Also use reflector when you can to lighten those shadows.

If you are going to shoot at f/1.8... you have to know that is going to let in a ton of light through the aperture and into the sensor. 

Last year when I shot football with my 60D, I was shooting at f/2.8 (which is about 2.3x less light than at f/1.8) I was getting shutter speeds of about 1/6000 and some at 1/8000 of a second. 

So I don't know if yesterday was cloudy and today was sunny, but that what you are looking at.

Since you are in the early phases of having the camera, I'd suggest shooting in aperture priority, setting the exposure compensation in the middle and allow the camera to choose the shutter speed.  If it was sunny, I'd probably set the iso to 100.... Then half press your shutter and look and see what your shutter speed is.  It should be at least 1/(focal length), so if you shooting at 100mm, then you should at least have 1/100 of a second.

Oh... and if it is still too bright, and you are at 1/8000 of a second with iso 100, then get a neutral density filter.  It won't change the colors but it will limit the amount of light that goes through the sensor. 

They really come in handy during the day when you want to take long exposures of rushing water and it is crazy sunny... but for a shot like that, I'd close the aperture.

Hi Omar, get yourself one of these, there are a few Brands around it doesn't need to be this Brand, B+W make them as do others, I use this one on my 24-70 to control light/movement.

Lee Filters also make something similar but in a Rectangular design that fits into a Filter Holder, but for Video the Circular ND Filter will work better, I think, I'm not much into Video.

Wow, look at that price, haha. But yeah, ND is the only way you'll be able to get wider open on the aperture. I do understand that the shutter speed needs to be at 1/50th sec for 24p ;) You probably won't get the aperture to 1.8 though outside in broad daylight. I'd use it on a different time of day where the sun is at an angle for better control.

Or get a regular (non-variable) ND filter and use ISO and shutter speed to adjust.

Just this morning I was shooting video outside with the 60D. Generally speaking, 1/50 is the shutter speed you need to stick with which only leaves ISO and aperture that can be adjusted. Since even at ISO 100 your f/stop is going to be really high that means the only way to get down as low as you want is with ND filters. In a nutshell they are like putting sunglasses on a lens.

So the settings I used were:

1/50 shutter
ISO 160 (I only use multiples of 160, or "native ISOs", but that is a different topic)
ND .9 filter
f/5.6

Like I said, to get down to f/1.8 in broad daylight without drastically increasing the shutter speed is going to take a crap ton of ND.

+1 stacking filters can get a bit pricy and might lose a bit of image quality too. If you really want good background blur I'd highly suggest a longer focal length.... There's plenty out there for cheap but for better IQ and background blur for a budget there's the 200mm f/2.8L or 70-200 F/4L with an ND filter might get the look you want and they're some of the lowest priced L lenses.

Do you have a source for this? I've seen people arguing for and against "native ISOs" aka "multiples of 160". It would seem really weird that ISO noise would be consistent across different sensors. I can believe that this might be true for some cameras... but for ALL digital cameras?   :o

With the 5DII people were advising to shoot at multiple of 160 for the best in noise performance, as 125 is digitally gained from 100 while 160 is brought down from 200 in-camera. So (theoretically) multiples of 160 are cleaner for when higher ISO is needed. I assume the 60D will be similar, as the sensor isn't any better in performance.

Exactly. So 160 is over-exposed by 1/3, and then SW tunes it down by 1/3. One way to reduce noise, but I prefer shooting with the real native ISOs (multiple of 100), and then decide myself how to tune the exposure for the shot.
