Noise Sample included when using "Batch Profiler"

Yes, there is an option for that in Options | Profiling. NI ver 7.5 PS plug-in Adobe Photoshop CC with 8.3 ACR I'm attempting to make NI profiles for the Nikon System 1 S1 camera. Using Auto-ISO, I'm able to get a total of 22 different ISO's from 100 to 6400. There are 1/6th stops between ISO 100 a...

Re: NI after RAW development

4) An then finally I was wondering: Why not create profiles based directly on the RAW data and also apply denoise directly to the RAW data ? Wouldn't that be the proper place to do the denoising anyway ? It would be one of possible places. NI is in another because it is much easier to work with sta...

Might be interesting to check and compare, but I suspect that you are correct that AutoFineTune will compensate fine.

There wasn't anything in the EXIF information regarding sharpness that NI could see.

It might be possible to use a tool that can write EXIF info, but that is probably more trouble than it is worth. Fine-tuning seems like it will do fine.

HowTo: adjust NI settings when ETTR done?

Summary: I use ETTR (expose to the right) for many outdoor scenics, and I'm unclear whether I should adjust NI settings to take this into account. Would this be an appropriate situation to use "Presets"? More Info: I've been using NR 6.x since late 2009, and have been impressed. Nice produ...

Separate profiles for HTP on/off (hightlight tone priority)?

I have a Canon DSLR with the option to enable/disable "highlight tone priority" (HTP). I'm somewhat unclear on just what HTP does, but my impression is that it improves dynamic range. I think this involves some hardware processing of how the photosites are interpreted. I think when it is e...

HowTo: use "sharpness" to distinquish profiles?

Summary: I'd like to be able to differentiate between various NI profiles for RAW/DNG images that take "sharpness" into account. I don't see how to do this. More info: In the "Preferences" dialog, the default priorities are: * Match: Input device (to distinquish between different...

Thanks for the reply. Looks like it is close to what I was asking about. After the steps you described, I have what appears to be a completely black layer showing. However, with CS4, my Info Window doesn't show Standard Deviation. It has document size, size, scratch, efficiency, etc. Am I looking at...

Is the procedure described anywhere? There are several reasons I'm interested in being able to quantify noise values. One is to compare different cameras at different ISO. Also to check if ETTR makes that much difference (see thread http://www.neatimage.net/forum/viewtopic.php?p=7700) The other is t...

HowTo: make Noise Profile smaller by removing Noise Sample?

When I make "Device Noise Profiles" (dnp) and look at them with the "Profile Viewer", I notice that they include a "Noise Sample". When I download dnp's from the web, I notice they are significantly smaller, and don't include the "Noise Sample". Is there a way...

Valid to compare camera noise with info from Profile Viewer?

I'm curious to compare the amount of noise between a variety of digital cameras, including a point-n-shoot, crop DSLR, and full-frame DSLR. From within NeatImage, I have looked at the "Profile Viewer", which reports a variety of numbers, including "Overall Profile Noise Level". I...

Regarding the idea about using several values related to exposure compensation taken from various (both standard and non-standard) areas of image metadata, it could work. It would not be very compatible (camera raw settings are proprietory, not standard for all raw converters, and perhaps even not ...

Oooops ... I was mistaken that Auto-Tune can be used with Auto-Profile. I did some further checking. Attached are screen shots. This first is with a blurred image deliberately under-exposed by one stop, and then using ACR 5.5 to increase the exposure by one stop. This could represent "push proc...
