PP3 parameters?

Learning on the job…
Already using pp3 in dynamic profiles…
But looking for an explanation of the parameters…
Most of them are self explanatory. Also, I already learned that they seem to be loaded in memory (i.e. updates in the pp3 will only be seen after restart)
Example, I cannot find [NoiseReduction] or something alike.

Thx!!!

May I ask what your use-case is? I think most users won’t edit the pp3 file directly, but will use the GUI to change settings and let RT update the pp3 file automatically. Or maybe I misunderstand your question.

Updates are seen on the desktop after RT is closed i.e. before restart, not “after restart” - and can be viewed then with a text editor,for example:

See [Directional Pyramid Denoising]

and [Impulse Denoising]

Have look in any PP3 … other functions contain denoising parameters, e.g. [RAW Bayer]

I don’t often edit PP3 files … it hurts my brain :wink:

I use the dynamic profile rules based on camera type and ISO value.
I started with copying a pp3 as a starter, but it did not always what I wanted, so I looked into the pp3 file and started tweaking (that’s what old Dinosaurs almost 62, do)
I could find many of the things I wanted processing. Noise Reduction seems to work as I want, but I could not find it in the pp3 - hence my curiosity…

But, I’ll have a peak at [Directional Pyramid Denoising] and [Impulse Denoising]

Thx all, never to old to learn???

I tend to save partial settings I’ve set in the GUI via ctrl + click on the disk icon

Finding the syntax is a bit much for me, much easier to save out the bit’s your interested in. Makes it self explanatory.

You pick a selection like this. (image is from rawpedia and might not be current)

I then often edit the saved pp3 to mostly cut out settings I don’t want the pp3 to override.

You can then stack pp3 files through dynamic profiles for different cameras/lenses/iso etc.

What does that mean? please expand.

It just means I have many partial pp3 profiles that build up to my default dynamic (and custom) processing. Some are applied as a base to all images, others only to some cameras/lenses/iso etc. Some also set detaults in tools that are deactivated. So that when I activate them the settings are what I usually need.

By having many small pp3 it’s much easier to build up processing for all files and maintain consistency.

Sorry, I don’t fully understand this response because, as far as I know, RT only allows one PP3 to be open at any one time.

However, I guess that means that the review image retains the prior settings if a new PP3 is “activated” i.e. opened during editing.

An interesting workflow indeed …

Cedric: see this screenshot which desribes what a partial profile is
{1AF3AE96-BEF8-4552-80AE-6B40A0A963EA}
In this shot its pressed. Here you apply a profile and always all values are set. If it is partial profile (and the button is released) like this one
{957731CA-18C4-4695-A358-0DD232DD3E41}
you would just apply the 3 values on top of what already is set.

Now in settings you can say
{BA9CA182-7C05-4FD7-A4E1-A49EDFC6B971}
which means you want a dynamic profile, In the settings for the dynamic profile you choose which combination of small pp3 you would like to combine based on attributes like isa, lens name, camera model, aperture and focal length

You can apply any number of pp3s to an image as @ChasingShadows says.

The settings can override each other or affect different aspects of processing. They can, and should, also be a combination of dynamically applied pp3s and ones you apply for special cases based on technical or aesthetic requirements.

It’s worth manually editing pp3s to make them even more granular than the gui allows. By manual editing, cutting out, you can separate out exposure, highlight correction and base curve for instance despite them being under one checkbox in the UI.

As mentioned it’s also worth applying presets for inactive modules. My crop defaults to 4:5 aspect of the top part of the image because a vast majority of my cropping is to vertical 4:5 to cut out ground. Similarly the perspective tool defaults to camera rather than simple which makes corrections a matter of one click.

Thanks, Karlheinz! I’ve never noticed that the button toggles when you click on it, duh.

Er, does “on top of” mean “replace” e.g. those numbers for ‘Curve3’ would now be as shown if they were different in the previous profile?

@nosle: The settings can override each other or affect different aspects of processing.

I think I get it because, as far as I know, it is not possible to have multiple sets of the same parameter affecting an image at the same time, unlike the GIMP - where you can sharpen a review image four times and it will just keep getting sharper and sharper each time …

Yes, the small number of fields is directly applied, without touching other fields. It is like you went to the tool manually and changed something manually. Of course the change itself do also impact complex tools like Wavelets, simply because some input changes are detected.

The base idea is, you can create small profiles for a specific creative aspect, which you can apply to any image w/o doing all the steps manually.

Thanks again, I’m beginning to get it. Are “fields” individual lines under a heading, e.g. under your heading [Color appearance] above, are there three “fields”: Enabled, CurveMode3 and Curve3?

Yes, I failed to know what that button up top did.

With y’all’s help, I can now envisage opening with a specific default pp3 and then applying successive partial pp3s on top of that.

I live and learn, thanks to this site …

You’re welcome. Life w/o learning would be boring anyway
