quick way to make a Cut out object look more realistic?

[jordanbcreativedesign]

so ive cut out some sunglasses and put them onto a cut out layer of myself, they look ok, but they still look like there pasted ontop of my face, lol , just wondered if there was an easy way to make them look more realistic and not stand out, they dont stand out too much, but i think it can be improved to look more real. i think its the outer edge cut of the Glasses which make it stand out, any quick tips would be much appreciated. cheers.

You need to post your image so we can judge what needs to be done.

Generally there are several issues with such compositions:

• Light and shadows
• perspective
• to hard or soft edges
• leftovers from the original picture
• wrong contrasts
• wrong focus

And I want to add

• different nosiness/graininess of the combined images

There are various ways to cut out objects, the method you choose will depend on the kind of image and your skills. For an object with a hard edge like sunglasses the pen tool might be the best choice.

That's good to know, we will not suggest anything in that direction again.

So the real interesting question is: why does it not look realistic enough?

So what about this:

Hi Jordan.  I'm going to come straight in with shadows.  It's not just that objects usually cast some sort of shadow, and one that matches the environment, but shadows also disguise that clean, high contrast, intersection between the background, and composited elements.

There are three Layer Style drop shadows here. A soft shadow at 90°, and two harder but smaller shadows at 45° and 135° to deal with the nose pads which are much closer to the skin.

Incidentally, it is supper easy to place images in this forum.  Simply copy it to the clipboard, and paste directly to your post with Ctrl v (Cmd v).  A lot of us use Greenshot to get grab the screen shots.  (if you have Windows)

Actually, I am going follow right up with perspective.  The human eye is very good at picking up on there being something not quite right, even when not knowing exactly what it is.  Perspective Warp is helpful, but finding the right perspective source image is worth spending some time on.

In my experience,  you'll have to do a bit of tweaking in terms of contrast,  color, saturation, perspective, even doing things like maybe blurring things a bit or adding a bit of noise to it.  it would help more if I could see what you've done or are trying to do, because there's no one size fits all solution for this.
