Perpective control only changes active layer?"

Hi

I'm trying to use the Perspective tool as I've done several times but this
time, I'm trying to use it on 3 layers. The problem is the tool is only
changing the active layer but not all 3 as I want. I've even tried linking
the layers but nothing seems to work.
Rotating, resizing or cropping works on all layers, so why not the
Perspective tool? I've even tried using the Repeat command but this doesn't
work either.
Your help here will be gratefully received!

Regards

Change active layer then repeat Ctrl + y will work with the perspective
correction tool.But Not the deform/ pick tool
Cropping works on an image. The others can work on all layers or just the
active layer

Why? If anyone remembers the rationale behind the design, they
certainly will not say here. Perhaps the designers thought of
Perspective Transform as similar to the Raster Deform tool.

In any event, we cannot change the design of PSP 9, so we learn how
to use its features to do what we want. I'd correct one layer, then
use the Last Applied preset on each of the other layers. This works
here as long as "Crop Image" is not checked until the final
application. You might have to promote the background layer to get
consistent corrections.

Except for the Move tool working on linked layers, no tool works
on multiple layers at once. The Crop tool works on the image
canvas, not individual layers. It's effect can't be restricted
to a layer or set of layers. Rotate and Resize are not tools.
Their effect is either applied to the active layer or to all
layers and cannot be applied to a selected set of layers.

Linking only affects moving layers. This applies to the Move
tool only and will not be recognized when, for instance, the
Deform tool is used to move layers.

See above. You aren't asking for Perspective Correction to
work on all layers anyway. As far as I can tell, you are asking
for it to work on three layers which you designate beforehand
in some unspecified way. At least that's how I read what you
wrote.

Run the Perspective Correction tool on the active layer. Change
the active layer. Retrieve the Last Applied preset for the tool
and run the tool again. Repeat for the remaining layers.

Alternatively run the Perspective Correction tool. Save this
step from the History Palette as a Quickscript (right-click and
choose Save To Quickscript). Change the active layer. Run the
saved script. Repeat as many times as needed.

I wonder if you would satisfy my curiosity. Why are you trying
to perspective correct three layers identically? I don't recall
seeing more than one (or maybe two) attempts by anyone to do that
so I'm curious about the specifics of what you are doing. Can you
please elaborate?

Certainly. I read more in Help then realised that Perspective & Deform
worked on the active layer & that linking seemed to work with the Move
function only. The penny then dropped that I could use the Last Applied
function & activate one layer at a time which I've now done.

I've been playing around with PSP's pretty unique Clarify function for a
couple of years now. I more often than not apply it fairly subtly but learnt
it was great for bringing out detail without effecting the global dynamic
range of an image. It is also very useful in extracting detail in
underexposed photos. It can be overdone & cause vertical or horizontal
banding, contouring & give an unnatural frosty effect to foliage. Used
repeatedly, it also desaturates. When I jointed Flickr last October, I
discovered HDR which can have similar effect to Clarify in that both can
increase the local dynamic range, albeit in very different ways.

I took 3 exposures of the Forbury Hotel, Reading in the UK & processed them
in Photomatix to produce a colour then B+W versions. I then took the
original -2 stop frame & applied the Clarify command to it - I wanted to
compare the 2 techniques. I had done this separately but decided to redo all
3 versions this evening. I can experiment with merging the various versions
later if boredom doesn't get me 1st :)

Be a bit careful. Heavy doses of Clarify can lead to some clipping
of whites and blacks. If you are concerned about this you can use
Histogram Adjustment (or Levels) to set Output Min to 10 and Output
Max to 245 before running Clarify. Afterwards you can tweak the
Low and High Clip Limits (the Black Point and the White Point) if
necessary.

Halos and grid-like patterns result from excessive application of
the effect.

There is a Clarify_RGB script written by Bart Hickman which runs
Clarify on the individual R, G and B channels and recombines them.
This emphasizes saturation. As an alternative to Clarify you can
use Unsharp Mask with a large Radius (e.g. 50) to produce a
somewhat similar effect. By checking or unchecking Luminance Only
you can disfavor or favor high saturation.

Some of the same issues, especially with regard to halos and
unnatural brightness variations, can arise with HDR. Here is
and example of the halo problems in HDR:

These are some examples of the problem with brightness:

Ahh, now it all makes sense. Thanks for the explanation. I should
have thought of that.

There is also a "Rusty's Dynamic Range" script which does local
contrast manipulation and tends to boost saturation. It avoids
clipping because the effect is applied using the Overlay blend
mode, which can't darken blacks or lighten whites.
