Third Party Manufacturers / Re: Nikon 750D real world review
« on: October 20, 2014, 06:40:49 AM »
Dpreview does some of that comparison, they have it for multiple ISO's and both RAW and jpeg comparison. The latter is what made me realize that Canon's high ISO advantage in the 5d3 vs 5d2 was merely Digic Magic, since the RAWs of both models were quite close.

The issue is, DPreview takes its sweet time to post 'full' reviews, so you one needs to be patient.

EOS Bodies / Re: Poll: Would you buy a high MP Canon EOS 5DIV?

I'd prefer more sensitive center AF points... would a -5EV point be possible?

Hi Jon: Thanks for tackling this polarizing topic. Canon makes a great system, and it will be obviously greater still of they used exmors in some regards...

But sensors apart.... as a novice not being able to be as articulate as you guys, I have always felt, that where Canon got beat on DR, was not the sensor, rather the footprint and subsequent processing of the raw file. Whatever algorithms Canon uses to build the RAW file and construct shadow (i.e. half missing) data; needs a re-haul.

This is quite obvious in banding... this is a digital artifact, not an analog output issue form the sensor...

What say you?

Thanks for the correction. Still pretty good for a non-dedicated Camera.

Third Party Manufacturers / Features on the iphone 6+
« on: September 11, 2014, 12:26:05 AM »
Nice to see cross pollination of technologies by different manufacturers:

The iphone 6+ has:

BSI sensor
Optical Stabilization
Phase detect AF on sensor
1080p 120 and 240fps !

Helps the consumer with choices, and pressures all manufacturers to up their game (just as Samsung is lighting a fire behind Apple :-) )

EOS Bodies - For Stills / Re: Features seen in the past and absent today
« on: September 07, 2014, 02:46:40 AM »
I wonder why canon packed older cameras with some very useful features that are totally absent in modern cameras. Here I refer to the Canon EOS 1D released in 2001 vs modern professional canon cameras.

I refer strictly to:

1/16,000 shutter speed
X-sync speed 1/500

I would think its to do with it being APS, smaller, lighter shutter, less distance to travel etc. Not on modern pro APS now due to cost / usage considerations I would think.
The 1D was an APS-H body with an electronic shutter.

Quick bit of research; also used CCD rather than CMOS which allowed the use of an electronic shutter. So as CMOS replaced CDD those features were lost.

What advantages do CMOS have over CCD (I know cost). but why would a fractional cost be an issue for a $5000+ body?

Technical Support / Re: Another my Stupid question = Sensor Sizes
« on: August 24, 2014, 06:43:51 AM »
Guys: Great responses, but I have a simple question and will take Nikon as an example:

Will the D800 have same noise performance of downsampled file to  12mp as the D700?

EOS Bodies / Re: 5D3 No Longer in Production
« on: August 17, 2014, 04:14:32 AM »
Looking at Canon's refresh cycle, I find it hard for them to ship a 5d4 prior to 2016.

Having said that, if they have truly developed a groundbreaking sensor that redefines performance at this price point the way the 5d2 did, then they could surely announce one sooner, because they would not have (just taking an example here) a 7dii sensor with 14 stops of DR (  :P ) selling alongside a supposed higher end FF body with a lessor sensor.

Lets see how the 7D2 measures up and decide if we want to ditch our 5d3's just yet.

Thank you all, especially Jon and McG.

Nice shot Mrs.... only that on my monitor, the flower shows as a deep burnt orange, not red  ;D

What do you think of this?



I chose the "Camera Faithful" profile under Camera Calibration. The settings can be seen in this before/after comparison:



Certainly improved over the unprocessed RAW, but still not fully detailed. I can much around the whites and blacks only and get it to where I want it, my issue is, why do I have to much around with it anyway. Is there an in body setting or LR profile I can use?

I think McGyver has some good ideas too.... the blues and yellows might be the issue and in trying to fix those, the raw converter over saturates the reds.

I tried the alt+white or black slider trick and while is made the reds better, the rest of the photo became unappealing.

I like my rendition (3rd shot) where I reduced both black and whites... and show the LR settings

Great discussion guys.

Is there an easy way of getting you the RAW (25mb file?)

Tks guys for the responses.

Jon, I did try the per channel red.... but it did not fix the issue, just washed out the red. In real life the flower has more red chroma, and I can match it on screen, but then all details are washed out.... it's not that easy of a fix... moreover I'd like a perm fix rather than spending hours everytime I shoot red.
