Global Apply

[gottsch]

Hi All,

I am starting to learn PI. My test dataset is images from the annular solar eclipse that I want to put into an animation. My starting point are about 120 images that I so far have converted from Canon RAW (CR2) into color channel separated TIFs.

I plan to use histogram, curves, unsharp mask, levels to further process. In the training video harry shows that some tools have a 'Global Apply' button. Unfortunately the histogram is not part of that. So what is the way to apply the same histogram operator to about 120 images? I tried open them all but the software crashed with memory problem. I can open subsets of the images and then apply manually, but that's a pain. What's the correct way to apply the same histogram operator to a larger set of frames? Even better would be to have a way to apply a prescribed sequence of operators to the set of images. Even better would be a way to save this entire processing pipeline to disk so that I can replay it at any time later.

I will ask questions on registration of the partial solar eclipse images later.

Your help is appreciated.

Thanks & Clear Skies,
Gert

first figure out your HT one one of the images and drag the triangle to the PI workspace, creating a process icon.

then open an ImageContainer and point it at all your images, and select a destination directory.

then drag the triangle of the ImageContainer process to the workspace, creating a process icon.

then drag the HT process icon onto the IC process icon, and away it goes.

Hi pfile,

That sounds great, but a little terse for a beginner. I.e. what's a 'HT one one' and how do I figure it out? Let's say I want to apply levels, curves and sharpening in the same sequence. How do I do that?

Thanks & Clear Skies,
Gert

"on one"
Try the whole chain of processes with one image, create a process container with all the history of that image, and apply it to an image container that has all the files you want to modify.
