Re: Fun with the Sony A7 and A7r series
Apologies for not coming back sooner, I had a lot to sort out yesterday with my parents.
Oh my, what a lot of assumptions, all very interesting and I do welcome feedback and comments as where would we be without them! So thank you one and all.
(Particularly thought yours was funny Doug... “Barry, are you overexposing your buns again? ROTFL” Nice one, how I chuckled my friend :ROTFL
First of all this was never meant to be a serious image, it was just a bit of ongoing friendly fun teasing banter between Michiel and myself + anybody else that wanted to join in, his straw rolls and my bread roll.
Thank you Leigh, nice to know that somebody elses monitor agrees with mine. :thumbs:
First up comes a comment from jlm...”overexposed about a stop”. No explanation or supporting evidence just a fairly bluntly put message.
Then I came up with Roll Mk2 as I did feel it could have been better processed in the highlights to bring out the detail further
- But still using the same “EXPOSED” DNG file, this was also met with more of the same non supporting evidence from jlm
....”definitely shows more detail in the hot spot of the bun, but i could use even more. not so much a monitor calibration as blown highlights. (I use a well calibrated Eizo CG 241, by the way)”.
Well now it seems that I have not only over exposed by about a stop, I have also blown out the highlights as well! Oh and I must be wrong because I’m not using a Eizo CG 241!
This frankly just isn’t true at all! As I have never shared with you the original files for you to play with - I do not have an Eizo monitor but I can still read and work a histogram.
For those that can even be bothered (and frankly why should you! :sleep006::sleep006::sleep006
, please see my Flickr photostream, for histogram supporting evidence of NON blown highlights. :thumbs:

Input ARW/DNG file (i.e. As Shot – ACR default setting – Untouched straight from the camera) which I worked from + The Output file Roll Mk2 with grey/white frame removed together with the white text so as not to confuse the histogram reading.
jlm...Talking of blown highlights, I will just add that I think your criticism comes a little bit hard for me to swallow
oke: when you yourself upload an A7R image to GetDPI like this,
Dsc0095web - GetDPI Image Gallery
It will be interesting to see if you leave it there for others to see or simply remove/replace it...I think the saying goes something like this “People who live in glass houses shouldn't throw stones”. Although mine wasn’t burnt out and yours is most definitely.
G43...”One stop lover and the white plate drowns in noise”....The discussion was about the exposure, not the noise, I do hope that was a typo “One stop lover” otherwise I do find that a little offensive. The noise in this particular instance has absolutely nothing to do with a badly exposed image in the first place because it wasn’t! It’s solely to do with the post processing that I applied deliberately later on by blending a B&W image Nik SE2 (Preset 024 Full contrast and structure to be precise – A highly grainy preset indeed) with the original coloured image and then re-saturating with vibrance to get a particular effect that I was after.
I agree entirely with “Exposure for the highlights. Spot metering, small spot. Then let the darks fall where they fall.” That is what I do but your assumption that the noise came from the bad exposure in the first place was simply wrong in this particular instance, it’s entirely due to the Nik SE2 preset.
BTW - UK Supermarket rolls are notorious for being well browned off on the top, yet quite anaemic on the sides and underneath as anybody will tell you here in the UK.
Werner I much prefer the B&W image again...Cheers Barry
PS. I’m off to Devon in a little while, so I won’t be replying until later on.
