Hi, you can take this way to do that:
One way to add effects to your wedding photos via Photoshop is by darkening or lightening the edges of the photo. This is known as the vignette effect. If you’ve ever taken one of those old timey photos before, you know how this looks. It will create a border for your photo and give it an antique feel.
If your pictures are in color, use the white vignette overlay as this will highlight the center of the picture and dim the edges. If your pictures are in black and white, experiment with both. The black border could give the picture more depth while the white will again highlight the center.
You could also feather the edges of your photo by using the Feather feature in Select menu. This will give the edges of your wedding photo a cloudy feel, creating a dream-like quality image. Or, you can use the Feather feature further in on your picture for an even more dramatic look.
Let’s say that the bride and groom are holding each other at the altar. The picture was taken with a wide angle lens, and it includes the person administering the ceremony, the altar, the bridesmaids and the groomsmen. Using the lasso tool, draw a rough line around the bride and groom. Then go to Select -> Feather.
Now, everything outside of that rough line is blurred, but the selected object is clear. This is also great for action shots, especially during the reception and on the dance floor.
Another wedding photo effect is to create a sort of glamour shots effect. This will soften up the photo, and it will make the photo look like a diffusion filter was used. This is great especially if the photo was too bright or if it was a special moment like the first dance.
This effect can be done by going into the Filter menu, and following the below steps:
Go to Blur -> Gaussian Blur.
Play around with the radius until you figure out which one looks best.
Then, click on Edit, and go to Fade Gaussian Blur.
Fade to 50 percent opacity.
Then click on Filter, and go to Sharpen -> Unsharp Mask.
Again, here you will have to play around with the Radius and Threshold until it looks right.
Then, click on Layer, and go to New Adjustment Layer -> Hue/Saturation. This should be between 10 to 20.
If the photo doesn’t look right, you will just have to experiment until it does.
