Spot removal problem

Beemer
When I use the Spot removal tool the spot reduces in intensity but does not disappear. I do not see anything in user help that explains how to set for 100% removal.

    Have you go the tool set to Spot, or Dust?

    Are you removing an isolated spot, or one close to other objects?

    I find the spot removal tool works quite well for isolated spots e.g. in the sky.

    However, if there are other objects nearby, it often produces a grey smear. In those cases I then try a clone layer which can often produce a good result.

    ... and the other thing you can experiment with is the diameter of the spot removal tool in relation to the size of the spot.

    For the avoidance of confusing terminology.

    "Spots" in the Sky are most typically dust (as in dust on a digital sensor) and usually best treated using the dust version of the spot removal tool.

    The "Spot" version of the tool is primarily intended for blended correction as in skin blemish removal and takes more of a "healing" approach which is not always idea for dust spot work.

    For removal of other objects in the sky such as a bird or a plane (used an an example but potentially for any large area of consistent exposure, colour and texture - sand for example) the Spot tool in Spot mode might work sometimes but a healing layer is likely to be a better option. Or perhaps a clone layer in some circumstances.

    With a layer you have the added control of "Opacity" to consider and you are not restricted to a circle.

    All options have some control over the size of the area assessed and fixed although the dedicated "Spot" tool uses some specific smart analysis realted to dust and (skin) spot blemishes whereas the layer tools just do what you tell them to do with healing adding its smartness to your instructions as best it can.

    Right, now back to the problem reported ....

    Grant,

    In my OP the offending spot was a pigeon in the sky with folded wings. It looked strange so I thought I'd use the spot removal just as I normally would when using Lightroom. I had only the original, i.e no other layers.

    As long as the object is a bit smaller than the max size of the removal tool it just should go away. The only situation I've faced of the removal tool not getting an object removed was a very dark (contrasty) spot almost as big as the max size (considering that dust is visible but generally pretty faint / low contrast). But now we have the option to do the correction via adjustment layer / clone which should work also in cases where the removal tool fails.

    I also had a problem using this tool. The same scenario as the original post, a bird in the sky cannot be removed with the spot or dust healing tool. It is intuitive to try to use this and eventually I did solve the problem with the local adjustment tool clone which produced excellent results. I think the point here is that if the dust removal tool was used, then a bird should disappear not just become less contrasty. Also, it would be good to be able to drag the spot healing tool too. This is not criticism, just feedback.

    Chiming in, I too have had that (with all recent versions of C1P). Small speck in the sky (bird, insect), not completely removable with the spot removal tool, no matter what size or mode. Adjustment layer works, but incurs unnecessary work.

    I have problems with Dust mode removing dust spots over pale shades like whie painted ceilings - in some cases it cause whitewashed rings, significantly brighter than object.

    Also Spot mode has problems with bigger-than-maximum brush-size objects.
    In some case huge dust particles (unfortunately i have to change lens in very dirty conditions and can catch even fur particle on camera sensor) can be removed with a few overlapping brushes.


    And very annoying is completely incomprehensible lack of Hotkey switch between Dust and Spot modes.

    Hi NN174596UL:

    in part you may be right that the max. size of the Dust/Spot Removal needs an adjustment. If I'm not totally mistaken it's 100px - and it has been this size for years now. This was fine with lower pixel count sensors but the same sized dust speckle which covered, let's say 50px back in 6MP sensor times covers now on a pretty common 24MP sensor 100px already.

    When the removal tool needs to be set bigger than the speckle then the 100px size indeed may be limiting and/or won't provide the desired full and clean removal. So this may deserve some attention from P1.

    However, as pointed out already in a previous reply there's the option to address a necessary more complex cleaning by the clone/heal tool via Adjustment Layer.
