Wrong ISO values for Nikon D70 images
Wrong ISO values for Nikon D70 images
NeatImage 4.0 is reporting incorrect ISO values for images from my Nikon D70.
Note that Noise Ninja reports them correctly.

Thank you, got it.
In principle, the problem is with Nikon firmware. It doesn't save the ISO rate in the standard location in the EXIF records.
We will see what can be done.
Meanwhile, please use Auto Profiler - it will build a profile directly from input image, without need to do matching agains ready-made profiles (which requires EXIF data, such as the ISO rate).
Thank you,

Przemek,
I hope too but in principle this is a wrong solution.
There is one source of non-standard images (Nikon) and there are MANY tools that have to work with these images. It is very inefficient to go and ask each producer of every tool to support Nikon. It is easier to and quicker to persuade Nikon to fix the firmware. You just have to go and demand Nikon to follow the standard. Otherwise, we will spend the rest of our lives trying to support all the deficient non-standard devices instead of increasing the added value created by noise reduction, sharpening, color correction, raw conversion, etc, etc.

Again - completely agree with you. Furthermore, they do this correctly on Coolpix P&S, why not on DSLR? I cannot find any explanation, except yours.
I have sent a question to Nikon support and the answer was basically "No"... Hope others will ask as well and one day we will get what it should be from the very beginning.

You are of course correct, it is totally lame of Nikon to put the ISO in the wrong place.
But the reality of the situation is that people (at least me) will use whatever software is easiest. Right now, that is Noise Ninja, because in its batch mode I can see at a glance the ISO values for all of my D70 images. But I still have to manually select the appropriate profile for each image.
I would much rather use the NeatImage method of automatically assigning the correct profile based on EXIF. But of course until you issue a patch to address Nikon's deficiencies, I will have to stick with Noise Ninja.
As a software developer myself, I sympathize with you. But sometimes you just have to implement a stupid hack -- like a special case case for Nikon DSLR ISO's being in the wrong place -- because of the realities of the marketplace.

Same problem with Canon Powershot Pro1
NeatImage 4.0 does not read the ISO speed for Powershot Pro1 images either. I have also noticed that 4.0 loses the Exposure bias reading that was available in 3.1.
This is the reading from 4.0
Device maker: Canon
Device model: Canon PowerShot Pro1
Compression: 2 bits/pixel
Exposure time: 1/30s
This is the reading from 3.1
Device maker: Canon
Device model: Canon PowerShot Pro1
Compression: 2 bits/pixel
Exposure time: 1/30s
Exposure bias: 0.00 eV
If you want a small (44KB) image I can send it to you.
