best way to cross-fade photos?

I want to put two photos side-by-side with a little bit of overlapped that
is cross-faded
Meaning, the photo on the left gradually trasition into the photo on the
right with no abrupt boundary

What is the best way to do this so that I can easily adjust the amount of
overlap region?

People familiar with adobe premiere would understand this: instead of cross
fading in the time domain as in premiere, I want to cross fade in the X-axis

A brute force way is to create a clipping mask for one of the photo and
gradient fill the mask. However, if I want to change the overlapped size, I
have to re-create a gradient mask, which is kind of slow. Is there a faster
way?

Hi Peter,
There are probably better ways but you might consider trying this:

Create a background layer evenly graduated from black to white. This
could be top to bottom, left to right, diagonal or whatever.
Then above that add a levels layer.
Then above that add one of your images with a 'multiply' blend
mode.
Then above that add your second image with a 'screen' blend mode.

This way the contrast slider in the levels layer can be used to move
your blend back and forth.

HTH,

And the black and white point sliders can be used to adjust the width
of the blend.

Is there not a merge function in CS which does just this??
