M9 higher ISO in practise

Interesting. It seems likely then that the new EU regulations will improve high ISO photos :)

 

That's why they did it, really. :cool:

After the yellow cast, meet the green :D cast (meaning environmental cast).

@ milchreiter : to me, apart the very promising usability up to 1600, best news

are these smooth transitions apparently (on screen) void of digital artefacts.

These don't feel digital at all, despite the general yellowish cast.

 

P.S. : By Jove and Holy Golly, Why did I read this post ? "No, I won't buy an M9, I'll be reasonable". "I'll work

harder with my M8 capabilities and wait the M9.2, cross my heart and hope to…"

(Telephone rings. Pr. Hel-Stampes grabs the unit.)

Yes ? Speaking. Oh, Mr. Ffordes ? A very nice price for the M9 ? You don't say… How much it was, please ?

:p

I've been asked to photograph at an event and have been warned that the hotel lighting is a mixture of tungsten and low energy fluorescent. Some rooms have one or the other and some a mixture. Before I travel I've been very quickly trying out M9 profiles built using the Colorchecker Passport. One good thing is you can build "dual illuminant" profiles that cater for illumination from mixed sources eg. tungsten/fluorescent. So far the results using a Gretag Macbeth color chart as a test subject have been very encouraging :). I'll be taking the Passport with me so I can generate profiles specific to a room's lighting.

I felt it mean of me not to give you some of the profiles. Unfortunately in several sections of the Colorchecker license agreement general distribution of profiles is forbidden.

 

What I have discovered is that domestic tungsten and compact spiral fluorescent illumination is considered to be sufficiently similar by the software that a dual illuminant profile isn't necessary. The software refuses to generate one for those conditions. Obviously you can generate a standard profile with the target illuminated by a mixture of tungsten and fluorescent. Those I've generated for compact fluorescent illumination seem to eliminate the "green" problem. Images developed using such a profile can be white balanced to look like daylight or a warm version without a hint of green/magenta. I'm very busy packing for the trip but if I have time I'll post an example.

The profile is ment to compensate for different color temperatures (K). The dual profile is best working, if you choose two color temperatures, which are quite different from eachother.

Within a certain color temperature profile, setting the whitebalance can be used to eliminate a color cast.

And I do regularly take a flash with me to ensure great light, though you can't just point a flash at someone and blast away :)

 

Agree. A flash can be an absolute life saver when the available light is unfavourable. I wouldn't turn up on a job without a flash (and backup flash) anymore than I'd turn up without my trousers.

I like to be discrete. On the other hand, the posted photos even required to be made without a flash. Flash would have meant: no photos at all.

The point about flash is that it is a choice. It can be both the right and the wrong choice. That is what being a photographer involves, making choices. Most of us here prefer not to use flash, at least with our Leicas, but there are times when it is the best choice, albeit not always good anyway.

 

Regarding high ISO practice, it seems to me that while camera performance generally is getting better at it, expectation is outstripping actuality. I think back just a few years when we were shooting 800ISO film and thinking the results were great. I wonder what we would think of the same performance today.

I think you are right and it is logical as well.

 

Some decades ago the first TV was a revolution. Today we all consider the quality very bad and now even non HD material is considered to be bad quality.

 

You can only judge, if you have the possibility to choose and compare.

In 10-20 years (I just guess), the sensitivity of sensors will presumably be much better and pictures will be looking better at ever increasing ISO values.

 

I'm looking forward to it very much, because I like natural ambiant light AND sharpness AND clarity without noise, because it reflects the "real" atmosphere.

And I like shooting inside a cafe, pub, house, church, museum etc.

 

On the other hand, brutal sharpness is not always rewarded and wanted as in the case of portraits with the 90 Apo Summicron, I guess.
