EOS Bodies - For Video / Video Editing Work Flow?
« on: September 29, 2014, 01:16:31 AM »
I am beginner on taking video / film making / videography (i dont know if these terms can be use interchangeably).

After recording a video using my 6D. The SD card shows .mov file.

  1. What is usually the next step? should I convert it to other format prior to video editing?
  2. What are the usual video editing that needs to be done? cutting/rejecting portions of the video?
  3. What is the usual final format (for still, its jpeg).

Thanks.

im new in taking video using dslr.

i got a 6D.
How about auto exposure. from darker scene to brighter scene or vice versa.
Does 6D or other dslr got this feature?

I never heard anyone mentions about this.

Thanks.

Damn i think i got it.

Imagine we got a sensor, divided into square, maybe 25x25 squares if you will (just for illustration).

Metering refers to the light (in terms of brightness captured by the sensor) AFTER going thru shutter speed, aperture, and ISO.

After the scene is being metered, now you got an image that consist of 25x25 squares, with different brightness on each square, (pitch dark to overexpose white)

When pre-flash is fired, we get another image.

Subtracting this two image, the camera can now define which is the subject and which is the background (Ambient)

flash power is fired such that exposure of subject is as many stops (depend on FEC) as compare to Ambient Exposure.

This raises few more questions. Anyway, I nice place to start.

This is what I've got. and a good place to start.
Before flash is fired:
    . camera meters the scene
    . pre-flash is release
    . with these two exposure information
    . real flash is release in accordance to the set FEC

Question next.
    . what does camera meters the scene really means - what important information is really take from here
    . same goes with pre flash..

just brain storming. (i still got no time to do the testing) maybe next week.

**please dont give comment like suggest reading a book or website. If you know something, please share it.

I cringe when I read stuff like this.

You would rather get opinions from anonymous posters on an Internet Forum, then read articles/books from identified established photography educators?

To each his own, but I just don't get it.

Good luck with it.  I hope you find what you are looking for. 

But there are some really good educational books/articles out there.

I understand your point, but you didn't get mine. I have read books, but tbh, most of the books says very long thing and so many example, introductions, and as a whole only trying to point to the same one concept. You need to read between lines and between words to grasp that one concept. 

Also those guys who suggest to read books, might already read that book, why not just tell me what they know. It isn't hard is it? and it will take me stressful to parse and look the answer to my question on a book that says so many things - in the end never says a concept.

And my question is simple, I just need some input before go make testing myself. Afterall you need build your theory first before doing the testing.

Also, everyone with a speedlight must encounter this question in their time using the speedlight.

I just covered my 2nd event in my life. This was a big learning opportunity. And my first time to use a zoom lens on such a scale. I use my 6D and rented EF 24-70 F2.8L II.

On my first event, I learned that I must not be afraid to set higher ISO to prioritize shutter speed. And slowing down is better.

I made a checklist before pressing the shutter. (Camera in Manual mode and Speedlite in ETTL 0 to +2/3)

    1. Is subject stationary or moving or approaching
            a) if stationary - use back button, shutter speed = > fl
            b) if moving - use back button, shutter speed = 160
            c) if approaching - use shutter button and switch to AI, and shutter speed = 160, use center point AF
    2. Set the composition (choosing focal length) and selecting focus point
    3. Check shutter speed > fl
    4. Setting Apperture
            a) Subject is near - Av > 5.6
            b) Subject is medium far - Av > 4
            c)  Subject is far - Av < 2.8
    5. Set IS0 such that metering is between -1 .. 0
    6. Focus and take the shot

i got 90ex.. so i say, why not might as well use it on my second body. So I encountered this problem/limitation.
Oh yeah ur right, it sends a preflash.. but still no matter what setting I use, on ETTL, I observe that flash is stronger still, where as I want it to just put out a bit.

OK, in that scenario what is supposed to happen is the flash would play no part in the exposure, you should, in theory, end up with a one stop under exposed wall.

However in my experience given that scenario, that is not what you do end up with, but in fairness that isn't what E-TTL is set up to do either, the assumption is that you have the flash on to light something so it tries its hardest to do just that! In my experience you end up with a slightly under exposed wall, but not one stop under, and the flash is clearly visible.

There are many situations where E-TTL will struggle, and not having a subject in the frame is one of them. Try your scenario with a more realistic set up, put something in the frame closer to give the flash metering something to work with.

Thank you very much for you input.

I will play a bit more with my speedlite tonight.
After that being said, I will note what you said, and see if I can understand my flash better. and get the most of it.

The main reason behind my question is: I wanted to full used my 90ex. even for just a bit of fill.
On Six burst shot:
    On ETTL, Flash fire alternately.
    On M mode (flash), 1/32, flash fire on every shot.

So last night, I was trying to get the balance right, use ETTL
and at the same time, flash must fire on every shot.
But even i set camera exposure to +1 and FEC to -3.
Flash fires strongly resulting to not fire on the next shot..

Do you guys mean that,

What ever the FEC setting is, when flash is ON, it will always makes the subject "well expose" at least?

Background:

Even if FEC is set to -3, flash will still give light such that 'subject' (refers to background if nothing in between) will be "well expose" (means standard exposure = 0)

No.

With flash on, the camera will try to make two exposure readings, one for the ambient and one for the subject. The ambient will be taken care of in Av and Tv automatically, you take care of it in M, the flash will try to determine the subject and with FEC 0 will assume the subject is 18% grey and send enough power to do that. FEC +3 will make the subject three stops over exposed, FEC -3 will make the subject three stops under exposed, but you have to determine how far off 18% grey your subject is, a bride with a white dress is going to need FEC +1 to +1.5 for instance.

If the camera can't separate a subject from the background it will try to expose the background as you have the FEC set, again FEC -3 will be three stops under exposed etc assuming the flash has enough power.

ok, lets constraints our topic to, camera on M mode, and flash on ETTL. and No subject, means we shoot a white wall for instance or a book shelves.

I agree to what you say BUT why for instance.
I set Shutter Speed, Aperture, ISO such that camera meters to -1.
Then I set FEC to -2.

Why is the resulting image is well expose. (as i remembered last night while playing with the flash).

I should make this test again tonight to confirm it.

Its been very long, I have been playing with flash. But never get serious and until now, I just guess and set FEC to between 0..+1 .

But how does really FEC work with regards to camera exposure.

This is how I thought it work, flash output power release will depend such that it attain the exposure set on FEC.
For example: FEC is set to +1, in camera manual mode, i set camera exposure to 0. thus the amount of flash output will release power enough to make exposure to to +1. (in ETTL mode of course)

Inline with this concept, it follows that when i set FEC to -1,
since camera exposure is 0, the flash should not even fire at all..
but the real result from testing is not like this. flash still outputs and make the scene brighter than 0 exposure..
Thus making my initial concept wrong.

Comment please.. Any expert care to elaborate the concept.. I want to grasp just the concept.

Thanks.

I used both dropbox and DVD-R. DVD-R for them incase, i need to delete their files in dropbox.

Since 2 years ago, I've been paying dropbox 9 usd for 100 Gig. Now, they gave free upgrade to everyone to 1TB.

Cool What!

Photography Technique / Can Recommend Ready made website
« on: September 16, 2014, 04:33:05 AM »
So now I am using zenfolio to advertise my work online. Zenfolio is basically a ready made customizable website for photographers.

Before I commit, does anyone can suggest a better alternative I can take a look before committing on Zenfolio?

Thank you.

If I were shooting an event for the first time. I would focus on the event more, anticipate and prepare for the shot. And be quick. I need my photographer instinct to be intact.

These advise goes for me also, coz tomorrow will be my first paid event. Only for 2 hours 10-12:00 local time, im not sure about the location but I assume its semi-outdoor and bright.

The problem is.. I GOT NO Zoom LENS.
These are what I got: 6D, 700D, 85mm 1.8 and 35mm f2 IS. 430ex ii with Graslon Dome Diffuser.
I was going to rent 24-70 F4L but it was not available. I was stupid to rent 16-35 F2.8 instead.

I tried using 16-35 on both 6D and 700D. There's no wow effect on the 6D. with 700D worst, I find it not sharp, AFMA error maybe.

So I decided for sure, to use my own trusted perfect matched 6D + 35mm and 700D with 85mm. Which always output nice photos.

As I've said. I need my photographer instinct to be intact. There's nothing more secure feeling than knowing and trusting on your gear. That's why I chose my prime for this event (16-35 will be useless, unless i cant step 5 steps back), in return I need to focus and anticipate more.

Does anyone can list down "remarks and conclusion or rules in layman's term", targeted for people who got two bodies FF and APS-C to be able to get better quality photo?

To rephrase it, if one got two bodies but only one lens without the photographer moving closer to subject. which body should I use to conserve image quality?

If ISO to be use is less than 800. should I use 6D and crop it or I better use my 700D?
On the other hand, if ISO to be use is >1600. should I use 6D and crop it or I better use my 700D?

This thread is so picture quality geek into sub pixel level, i dont even know if my question is appropriate.

Thanks in advance.
