Don't be confused, the article is not very good advice and what he is suggesting doesn't actually work.

But gentle ETTR does work, an up to one stop over exposure I find to work well, especially when shooting darker subjects with more emphasis on darker tones, much more than that and it becomes difficult to retain the colours and tonality of the original scene.

Of course you always have to watch for clipping, once your pixels register white they have no detail, but if you meter for a scene and make an EV adjustment for the subject, giving it an extra stop, so long as you don't clip too much, often works well for your darker tones.

After I read this article from op, I tried set exposure compensation to above +1 and did check histogram for clipping, its a plus work. (previously I just set to +2/3 at most) - to preserve image quality (less noise) to maximum at high ISO.

Then I get a bit used to +1 and 1/3 compensation. Then on the last shoot, I found my photo clipped.
Tsk Tsk Tsk!!!

I crop retaining 2:3 aspect ratio, because 4R photos and photobook dimension is 2:3 also.
Last time I like 16:9, but nowadays 2:3 seems normal and convenient to my eyes, idk why.

thanks. I guess I need to stop fooling myself that 50L is better, but but I like to use an L Glass.
I have previously own good 85mm 1.8 but sold it coz of the need of more versatile lens.

It feels hard to re buy lens you once sold already.

I don't want make same mistake buy selling 50L for a 6D and 85mm 1.4.

Tsk Tsk. I guess I just need to work hard to get that another fullframe.

You can also check graslon diffuser. - they say the bigger, the softer, so I chose this.

Just curious.
I wanted best 85mm set up at aperture F2.

I have 70D and 50L.

Would image quality be better if I got 6D and 85mm 1.8 instead?

image quality refer to wow effect - sharpness, color, contrast, etc.

It is simply a matter of what your usage is.

The 70D had autofocus for video, while the 5D MK II has better low light response, and will give better IQ and wider angles given the same lens.

If you find that you are using telephoto lenses a lot, the 5D will appear to be much wider, so you will need a longer telephoto lens to get the same view.

Autofocus is not a issue for me, I've taken many action photos with my 5D MK II with great results.

I looked at new 70D's several times, and I wanted to like it, but it just turned me off each time.

70D af not working with 50L. As far as I  am concerned.
Im stuck with live view.

Buy a better camera body (like the 5d3/1dx af system) and couple it with the newest lenses that have enhanced precison vs. older L versions, that's for example the 24-70L2.  Top-notch af precision is expensive (Canon makes sure of that), another reason you need a good af system is that you have to prevent focus & recompose errors by af'ing right on the spot.

Thanks for the comment regarding how to improve precision.
I used my 50L with 70D usually. Still can not AF properly. But when I use 50L on 6D, it nails focus.
Tbh, 6D does a good job doing AF. even outer points, when I feel lens af locks on, means it really is on focus on the 6D. Never miss anytime. Unless user error.

But on the 70D, I keep praticing shooting my wife, but they miss every time.
I put af on her eyes, still does not make it. I put af on her smile, it won't focus.
But it locks on object.

Maybe because there's shadow in her face, or no contrast enough, or may hand shakes, contributes to not focusing.. But what ever it is. My 6D af everytime, even face is under shadow.

Still fustrated, need to practice and test more. Both 70D and 50L already was service by canon.

Next test, I will use AF assist light from speedlite, and see results.

Oh my, afma seems to be the most mis-understood issue on the planet (next to women, that is). Afma simply adds or substracts a bit of focus from the point the camera intended to focus on. It makes af more reliable as in "accurate", but not more "precise":

Hi Marsu42,

If afma makes af more accurate, how can we improve precision? is it inherent with the lens and can not be fix?
is there a measure the describes lens precision range?

I got a 50mm 1.2L, so I was wondering how precise it is, and if it is according to standard for 50mm 1.2L.


Post Processing / Re: Choose a Monitor?

I don't understand the concept of dedicated video card.

lets say my laptop got dedicated video card, does this feature only work for my built in monitor? or this feature will also be extended to the external monitor?
if yes, will I stress the video card, if the higher the resolution of my external monitor connected in my hdmi port?

what if I add video port thru usb? will I be using the video card of laptop?

architecture wise, how is the block diagram connection of video card -> built in screen -> external monitor with reference to Video Signal?

I've been asking this at the back of my head ever since.

Hope someone can shed a light.

Hmmm, still no features like:
- touch screen
- Wi-Fi
- fast AF in live view
- pop-up flash

I guess Canon believes only people who pay less than $1,000 for a camera deserve those. (Or those who leave them and go Sony.) The more you pay, the less you get. Makes sense, right? :)

And please don't come with the usual BS "only amateurs need those features" crap. The touch screen on the new 5500D can be used to pick focus points with your thumb when not even in live view. In ten years, every pro camera will have those features. A pro camera should be just as easy to use as a smartphone camera. As long as that's not the case, volumes will keep falling like they have since the first iPhone came out. and CaNikon deserve it.

only amateurs NEED those features. :)

Thanks for the share. I'll surely buy this e-book.

Get yourself a Colorchecker from X-rite (my original reply), this will help you set up a color profile in horrible light and, wait for it... it has grey chips and white balance chips. You can do it all from there.

Look, lots of these so called pros here on this site are pros in their own mind... and would rather go on and on about this or that. They're easy to spot, they can't show any work for "privacy" issues and they're more interested in listing all of their precious gear. Take anything said as gospel with a grain of salt the size of Gibraltar. At the end of the day, it's you sitting in front of the computer looking at your own work. You choose what you like, you're the photographer. Work flow is important and if something can make your life easier (ie using a Colorchecker), do it and move on. All I know is when I have a few hundred photos to get to the client the next day, setting up a color profile gets you very close to what need. You will then have to make a judgment call and decide where you want the WB when dealing with mixed lighting... there is no simple one size fit all answer.

Your right, colorchecker it is.
after all what is better than having the same object in your photos and also in your hand while you are editing.
Thanks. I will go this direction.

The first thing you have to realise, WB is subjective. If you do a 'true' WB at an event and then process all your images to that value then you often find all the character from the event disappears, effectively neutral white has no ambiance so dialing in a perceived WB value (the subjective part) will better replicate the feel of the event. Obviously the type and style of event will dictate how much ambiance you want to leave in.

Exactly my thought, in many cases, perfect white balance is nice, but in many cases, I prefer to balance colors to suit the way I saw them.  I photographed a event last week where the director used a lot of colored lighting.  White balance makes no sense.

Thanks for your example.
How did you set (attained) your white balance for this?
I bought expodisc expecting that alas my problem solved, in the end expodisc only help a bit.
my vision still has the last say. They never mentioned that in the expodisc review.

I understand that my question was answered a lot of times.
in the end, while editing I will use my vision to judge;
I'll start with using click white balance tool. then proceed using the white balance slider
to adjust and judge how really the ambiance look base from my memory.

Any suggestion on nailing the skin tone? - color passport checker?

If I use speedlite. I always shoot manual mode with flash set to ettl.
Professionally wise, I chose manual, I manually set aperture, shutter speed and ISO, depending on the meter reading on the viewfinder.

Reason behind is, you take control. Usually when I shoot auto mode, there's often tendency the resulting image for some reason gets underexpose or over expose, during this time, its time consuming to think what went wrong.

so I better use M mode. with flash exposure compensation.

My suggestion is, use a diffuser, use M mode and ettl. set ettl to +2/3 meter exposure between -1 to 0. focus and press the shutter.

I use the Colorchecker Passport for all event work with mixed lighting... make a DNG dual profile and use it for every shot in the same area.

I will consider your workflow, care to elaborate what does make a DNG dual profile means?
