Question

How can I rotate an image and scale about origin point when viewing it magnified ?

Hi,

I have two images taken handheld of the same subject from the same viewpoint same focal length same aperture etc seconds apart and have one at 50% layer opacity.

I position this so that it matches the image underneath in part of the picture and drag the origin to that spot but it needs rotating to marry up.

when zoomed in to see I am marrying it up accurately and getting a perfect match the rotate handles are not accessible. One has to zoom out to see the handles sitting beyond the canvas but then accurate matching is no longer possible.

How can one rotate by hand when zoomed in ?

Also it needs a slight rescaling as I do so, so holding alt down and dragging the handle to scale about the seed point/origin is needed but again handles are only accessible when zoomed out and at that mag I am not able to be accurate. Also alt stops the rotate command from working !

This control is fundamental tooling yet seems decades out of date in its handling limits.

Otherwise the ability to select certain points on the second image and then select same points on the target image and say refit photo best fit would be a superb tool.

(  options to allow for local distortion or uniform scaling maybe)

I have in fact loads of such pictures to rotate and scale to marry up.

is there maybe a plug in that provides better image rotation and scaling ? Anything that matches one photo to another ? Selecting source and destination points would be super.

I am CS6 .

    The Nafigator panel might work for you as a workaround. You could zoom out your image so that you can use the bounding box to rotate, and at the same time see the image larger in the Navigator.

    You can use ant of the 9 anchor points the teh free transform optoin bar  set the rotation angle and scale percentages  there as  well.  In the bounding bot display you alsi have the option where toy can grag and position the rotation point.

    Hi, someone has selected correct answer yet is that not for me to decide ?

    This question has NOT been answered until I try the suggestions and see if they allow for the precise rotation and scaling at the same time about the 'anchor' point that I am after.

    Hi Merlin3.  Mods and admins can select a post as the Correct answer, but none are so set as  I type this, so I'm guessing that another moderator has unchecked the Correct answer.  Barbara and JJ gave you good advice. The other poster spent a long time answering, but appears to have not read the actual question.

    I don't know of any way to rotate when using Free Transform, and the outer handles are not visible, other than using the Options Bar as Barbara and JJ showed you.  As well as entering values in that field, you can also 'drag' to the left of the angle value field.  You can also hold down the Shift key while using the up and down cursor keys, to rotate by 0.1°.  So one workflow might be to drag to make an initial 'coarse' adjustment, and use the cursor keys to fine tune.

    I can't think of any reason why you couldn't make an Action, or several Actions triggered by shortcuts, that rotated by say 10°, 5° and 1°.  The weakness with that idea is that you would not be able to adjust the centre rotate handle, but you could chose a workflow to match your current requirement.

    To align the two images, you can select both layers in the Layers panel and choose Align from the Layer menu. That should save time from having to zoom in to align the images.

    As far as rotation, I know this isn't exactly what you want, but when zoomed in, you can use the Options bar to adjust the angle.

    If you click inside the cell for angle you can use the up and down arrows on your keyboard to rotate 1/10th a degree at a time. If you hold down Shift, the arrow keys will rotate 1 degree at a time. If you hold down Shift+Alt, the arrow keys will go in 10 degree increments.
