So it does. But I still prefer attachments. Links break, and then members reading this a year from now won't have a clue about what we're talking about.

It looks like you are indeed masking the image, but its not using the mask to make a cleanly cut-out image. The dropshadow is ignoring the mask.

Are you using a layer mask? Try flattening just that one layer, or using the mask to make a new selection and then delete the background.

It seems to me that layer masks should be compatible with drop shadows. Are you using Photoshop's builtin dropshadow function? But regardless, if you have a layer with a cleanly cut-out subject, you should be able to make good shadows.

Hi Doug,

Yes I am using a layer mask, I am still learning alot about photoshop, and masks are not something I have any expertise in yet. But here is what I did in this example.

1) opened up image #1 (background)
2) opened up image #2 selected the women a best as I could. Did an edit copy.
3)Went back to image #1, created a new layer then edit-pasted the women.
4)I then created a layer mask and cleaned up areas that needed to be removed.

So now my image consists of 2 layers in total, layer 1 being the background, layer 2 being the women and to the right of that it shows the mask

I then highlighted the top layer (women) and selected the "f" down at the bottom of the layer dialog box and then selected drop shadow.

I am confused on one thing you mentioned, is there a way of somehow merging the image you were masking and the mask itself? You mentioned "try flattening just that one layer" I am not sure how that is done. I know I can flatten layer 1 and the background, but maybe you can tell me how to go about flattening just that one layer.
Thanks - Carl

Just right-click on the layer mask icon and select 'apply layer mask'.

There are also other options there that might be useful. It allows you to make a selection based on the layer mask, which could be taken to the original and used to copy a new layer (if you didn't want to lose your mask).

Experiment and use the history pallette to undo until you find the method you prefer.

Well I think the problem is solved! Doug taking your recommendation and applying the layer mask solved the problem I was having with the andromeda shadow filter. It now gives me a good drop shadow.

As mentioned, I was only having the problem on certain occasions with photoshop internal drop shadow. I do think that it is designed to work in conjuntion with masks but for what ever reason this problem occured from time to time. My guess is that if I applied the layer mask I probably would not have the problem.

In either case, thank you to everyone for your suggestions and help - Carl
