We always follow feedbacks, and about our film emulation, we delayed the Kodak pack in order to be able to make everyone happy...

Now our next film emulation packs (and perhaps in the next months the updates for the older ones) will include for any single film emulation:

LINEAR (linear info from the sensor with film emulation applied)
FLAT (base exp curve, no contrast)
STD (full exp curve and contrast)

so, for this picture on Adobe std

Thanks for listening to my feedback, that's really an improvement for your film packs.

@Ulysseita@ - I've been following this thread with great interests. If I interpret how the profile calibration works, it means it'll extract the sensor raw data and convert them into a standard calibration.

In case of the M9 I find e.g. it often shift neutral grey colors (say a section in my bedroom that I know very well) with some cyan cast, even with Adobe standard, and my other much newer camera never or rarely do that. I was under impression that it was how the sensor rendered right from the get go so if the cast wasn't there in the

Appreciate the samples, easier to understand looking at samples than words. As always an amazing effort there!

busy days on this June...

We talked so much about the emulations and color signatures for skin tones and portraiture in general, but not so much on landscapes...

Well.. below there are many samples of the same picture, captured using one hand on Ricoh Gr... during a flight with my drone on this super colorful sunrise.

Just a profile swap, no grain or noise added, standard curve.

On the Ricoh GR 3 - do you use the AE highlight-weighted metering setting?

Even setting the exposure compensation on +0.7 my images get real dark - and more so in the REPRO profile...

Am I too concerned with the camera histogram being slanted to the left (even at +0.7 exp comp), and should I just go ahead and slam that Lightroom exposure slider to the right in the GR III's REPRO profile?

I can't remember the metering, my camera was a GR, the one with 15mpx; never had problems of underexposure and always ready to work ( honestly I would say the perfect camera exist, his name is Ricoh GR.. )

We are close to the release of our Kodak Film pack.

After Ektachrome, Ektar will be included.

our new way to manage film emulations is :

LINEAR (linear info from the sensor with film emulation applied)
FLAT (base exp curve, no contrast)
STD (full exp curve and contrast)

I've just purchased the New Kodak film profiles and really appreciate that it comes in "Flat", "Standard" and "Linear" contrast curves! I hope this will be done for the other film profiles as well.

Here is a sequence showing Adobe Standard profile, Kodak Ektachrome (flat), Ekta 100 (flat) and Portra 400 (std):

Big difference between Adobe STD and the others.

Cute kid... AND he looks thrilled

Bought the basic pack for my A1, and did a few edits today. It was quite a revelation! I don't think I'll even bother trying Lightroom's built-in profiles in the future.
Some of the emulation profiles are also very tempting - I just need to decide which one to get.

Yesterday I had some time to test one of my new lenses on this weird summertime, so cloudy and hot.
Ideally a sandbox for our new Ektar!

The pictures were all shot by M9 and Tele Elmarit 90 and Zeiss zm25 but the exif are all setted on zm25 (cron28).

Very cool photos, the M9 still has some stellar image quality.

Some of these have lovely results!
It is deflating though that photos simply taken with a $5000 camera and $2000 lens alone still isn't good enough. Kind of ridiculous how costly it all has become.

indeed, I can't explain why, I still LOVE it even we live in a world with FF with 61mpx and MF of 150mpx...

Thanks!

We keep raising the standard of what good enough is. 10 years ago, images taken with the current gear was good enough...not so today.
