EOS Bodies - For Stills / Re: Upgrade to 70d or 760 d ?
« on: February 13, 2015, 04:47:48 AM »

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?
« on: January 31, 2015, 10:13:31 AM »
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.

EOS Bodies / Re: Bingo! New Canon 5Ds has 50.6 MP new rumored specs

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?

Photography Technique / Re: Indoor Wedding help

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?

I started covering event, and recently got problem on color of my photos.
So I calibrate monitor and take into account white balance of scene,
and correcting white balance in post processing as standard first step to address this color issue.

I bought expodisc too.
during dpp editing:
photos taken indoors at fluorescent white light, when i try to click on white object, or try to use the photo from expodisc as my reference white balance. the resulting photo ambient light look worst than when use the auto whitebalance settings. look worst, i mean, ambient light and skin tone more saturated yellow.

So my question is, is white object and grey photo from expodisc really is the best reference for white balance?
or I need to trust my vision (to identify color cast and adjust accordingly)


EOS Bodies / Re: Canon EOS Rebel 750D Spec List [CR1]
« on: January 21, 2015, 09:47:47 PM »
Maybe this camera cater for the entry user market.
Professionals will always think more than twice to use rebel - so pro camera such as 70D above (my opinion) is safe.
entry market is now looking for high tech features like touch screen, NFC etc.
thus, these cameras.
you won't understand unless you look at business perspective.
- my opinion

Software & Accessories / Re: Any value in using DPP along side Lightroom?
« on: January 19, 2015, 10:46:27 PM »
I will try lightroom and see if workflow is faster.
For me time is more precious than the small advantage of dpp (if there is).

I find dpp very slow for editing hundred images at a time.
Also, if dpp does not allow me to copy only specific setting to other images.

example, I only want to copy noise reduction parameter to other images.
but theres no way to do that in dpp, all settings (brightness and sharpness are also copied).
main reason why need to try lightroom.

Any comment?

Software & Accessories / Re: DPP 4.1 - No exif on jpeg upon conversion.
« on: January 19, 2015, 03:17:38 AM »
Thanks. I found the culprit.
    Shooting info Setting: was set to remove all shooting info.

My mistake, but honestly I found canon software menu not so understandably organized.

Wehen I convert from Raw to Exif-Jpeg.
The resulting Jpeg does not have exif.

Am I missing something? or this is a bug?

I've just tried it with DPP and the jpeg does have EXIF info.

If it is so. I wonder what could be the culprit.
The hardest thing I could try is re-install DPP 4.1.5.

I will do and update.

Lenses / Re: New Rebel & EF 11-24 f/4L USM Coming Shortly
« on: January 18, 2015, 09:29:35 PM »
Ok so reading through these threads I did see one person say that this is a perfect lens for him because it will likely be relatively light and really wide and therefore perfect for using when hiking to get amazing landscape photos. 

I assume that 11 is so much better than 14 that it will be better than using the samyang and that the person using the 11-24 is a much better hiker than I and not worried about tripping and breaking a 3K lens.  Who else is this lens for?  It does sound like people have been dissapointed with the 16-35 II.  if this is just a better lens then it might replace that but I always felt that the 2.8 and 24-35 range were important for that lens for event photography. 

I'd love to know what applications this lens is great for...It sounds like a professional landscape lens to me....the wide angle equivalent of the 400 2.8 for sports photographers.  If that is the case and it performs as well I'm sure those folks will be thrilled and the rest of us will just gawk at their amazing photos. 

However, that is a pretty niche group.  The rest of us will settle for 17-40 or 16-35

Architecture - it's what pays my wages ;-)
Landscape I enjoy, but there's not (nearly enough) money in it (well, not doing what I like and where I live in the UK)

I have the 14mm and it's OK for many things where I want wide, but for architectural use I prefer the 17mm, shifted up/down if needed. Also the 8-15, with remapping the image geometry in varying ways.

It takes a fair bit of practice to be able to effectively use very wide angle, but it enables me to get some shots that I couldn't get in other ways. As I mentioned earlier, I'm looking forward to seeing how it expands what I can do - 14mm to 11mm may not sound much to some, but combined with the 17mm and 8-15, I'm just left waiting for a camera to replace my 1Ds 3 ;-)

I recently produced a new web site just for our architectural work and IIRC, over 50% of the images I used the TS-E17 (add in the TS-E24 and EF8-15 and it's probably over 90%)

I'd expect an 11-24 to contribute a fair bit to our bottom line ;-)

PS If anyone's curious, I was recently interviewed by X-Rite specifically about my architectural photography

Thanks for sharing - regarding architectural photography and other stuff. More power.
