How do you add or stretch seamless paper background photoshop??

My seamless paper is only 10 feet wide only. There was a party of 15 people in the background. At least 5 people on each side is not in the seamless paper background. How do I add or stretch the paper in the background?? Really need your help guys! TIA!

Not so simple in your case. Stretching the background is easy; just make a selection, ctrl+t to transform it and pull one of the side handles out.

Your first step however, is going to be to cut out the people so you dont stretch them (this is the hardest step).

After you cut out the people and stretch the background you will have to clone in some areas aof seamless around the people as it will be missing.

Thank you Robert. Is there a tutorial video somewhere on youtube showing step by step?

maybe shoot them as two groups?

Tried everything. They wouldn't listen.

It will take a little time and patience but it isn't that difficult....I do it for several sports teams that I photograph on a backdrop that are too large for the backdrop. The first step is to duplicate the background layer. From there, carefully create a mask to cover all of the background that you want to get rid of (this will require careful cutouts of every individual that isn't on the background....a Wacom tablet is really handy for this step). Once you complete that step, you can create a new layer that will go underneath your masked layer and use your current background to start cloning in a new background over the bad areas (you can actually be a little sloppy with this because the mask will cover any mistakes). There will most likely be some type of gradient with the background, so be careful to clone from areas with the proper tones. Once you're finished with that, you can use your burn tool to make it appear more realistic by adding in shadows where they should be.

Another way to do this would be to make a selection around all of the people, then choose "selection>invert" then choose "new layer via copy". Now you will have the background in a new layer. You can select the non seamless background areas and use content aware fill to fill them in. You can also do this where the people where. Then you just move the group onto another layer above the background. (assuming you saved your selection).

Another way to do it would be to create a new layer, fill it with white, and then add a subtle gradient to it. This can be done by creating a curves adjustment layer, then using CTRL+I to invert the mask to black. Then you can use the gradient tool to create a gradient on the mask to replicate the light falloff you had on your background. If the light falloff was a bit complex you can use the lasso tool to create selections in the appropriate shapes (where the light will be), fill with white, and then use a gaussian blur on the mask to replicate the light falloff.

Then it's just a matter of bringing your subjects up onto the new layer. You can do this by creating a selection around them via the selection tool, the pen tool, or you can make a rough selection around them with the lasso tool. Then you can move them onto a new layer above the background and use a mask to refine the selection.

Gosh, I wish you guys have a video for this type of work. LOL. I'm reading but I can't seem to grab the concept. I'm a visual learner guys.

YouTube has tons of tutorials

Got a link? I was searching for a seamless background, but I couldn't find any.

Thanks. I was looking at those video before. I understand the stretching part but I don't understand the cutting and pasting part.

With "facy" Photoshop work, the best approach is from the "ground up". Start with a combination of the Lynda.com tutorials (you pay a month-to-month subscription then go at your own speed) and then there are books, tons of books on Photoshop. They offer a combination of "lessons" and visual aids, and many of them have DVD tutorials attached.

Really, there is no simple "shortcut" to learning Photoshop skills...

Next time, ask yourself how wide it would be if you ran it horizontally?

Lets see the picture. Best scenario is that there is some angle that you can exploit (normally luminance and/or color contrast) in order to simplify the masking.
