Lightroom/Camera Raw: Radial filters in presets should be given position relative to crop

Currently, when applying a radial filter to several images at once, either through auto sync or through a preset, the radial filter is applied to all images based on the absolute pixel position in the uncropped image.

This behaviour is unintuitive when radial filters are used for effects such as darkening or blurring the borders of an image.

I would like to argue that the intuitive thing for radial filters would be to position relative to the cropped image borders, and not position in absolute pixels but in relative terms.

For instance, if I have a group of photos where some are cropped in size and some are full res and want to apply a radial filter with a blur, I want the effect centered. However, if I center the radial filter in a cropped image, the filter will be off-center in all full resolution images (and vice versa).

If Lightroom saved radial filter position in relative terms (50%, 50% would be centered) the radial filter would always end up centered, regardless of cropping.

Regular graduated filters are usually positioned in relation to image features such as a horizon, so I would argue that the current behaviour (absolute position on the un-cropped image) makes sense. However, radial filters are (probably?) more often positioned in relation to the image borders and would be better off if they were positioned in relative lengths and relative to the crop.

This suggestion would be a good idea if it were a "relative positioning" option.

Radial filters are not only used for image borders. I more often use them to apply localised adjustments to one or more elements in an image. If applied with relative positioning before cropping, then after cropping could move the radial filter's position to the wrong part of the image.

That is true. Didn't think about that.

How about if radial filters (and regular graduated filters for that matter) are applied relative to crop when applied using a preset, but relative to the raw image when applied normally, copied or synced?

My thinking is this. If you want to include a filter in a preset, you probably want it applied relative to the crop or border. For instance, when creating some kind of vignetting effect using the radial filter, or for applying a generic ND-grad to the upper half/third of your image.

However, when applying filters manually, you will want them absolutely positioned relative to the image pixels. As you say, you don't want them moving around when you crop.

Copying and syncing is somewhere in-between, but if they provide absolute positioning then there would be quick batch-operation alternatives for both types of filter positioning. Presets for relative positioning and copying/syncing for absolute positioning.

And a small addition: Any filter that is applied using a preset and then manually moved/adjusted should lose its relative "status" and become an absolutely positioned filter.

Not that I'm negating what you want—but while waiting for them to perhaps act on it, for your border vignette, would using Post Crop Vignetting work better for you with a preset? It works on images I've cropped in CR to various sizes, creating the same vignette in all of them.

I usually do use Post Crop Vignette for regular vignettes. In this case I was trying to apply a blurry vignette with sharpness -100 to a batch of photos.

Right. No help if you're doing anything  beyond darkening/lightening the edges.  Good luck with your request.
