Background Remover Basics for Paint Shop Pro

Article by Michele McDonough (79,057 pts ) , published Sep 16, 2009

In Part 2 of this series, we look at how to use the new background remover that comes packaged with Corel Paint Shop Pro Photo X2 Ultimate to isolate basic solid objects in a digital photograph.

How Hard is it to Remove the Background in a Photo?

The difficulty in removing the background in any digital photograph depends on a lot of factors, but one of the biggest obstacles is the shape and structure of the object that you want to keep. If you’re working with an object that has a lot of “fuzzy” edges, like a long-haired cat, or one that has a lot of interior “holes”, such as a window or shrub, then the process of removing the background can get a whole lot harder.

The easiest type of object to isolate in a photograph and remove the background from is one that is solid and has well-defined boundaries. We’ll use an example of this type for our first guide on how to use the new background remover tool in Corel Paint Shop Pro Photo X2 Ultimate.

Removing the Background from a Solid Object

Original Orange PhotoBegin by opening the photo that you are going to be working with in Corel Paint Shop Pro Photo X2 Ultimate. If you plan on making any other adjustments to the photo, such as cropping or resizing, it’s a good idea to perform those tasks first. It’s also a good idea to save your photo after every change is made, and use a different file name for each saved image so if you make a mistake, you don’t have to start all over from the very beginning.

When opening a digital photograph in Paint Shop Pro, its layer type will default to Background. Before you can use the background remover plugin to edit the photo, you must first convert it to a full raster layer. To do this, choose Promote Background Layer from the Layers menu on the main toolbar.

Promote Background Layer

Now we’re ready to use the background remover plugin to edit the photo. From the Effects menu, select Plugins and then choose Background Remover 3 from the Image Skill submenu.

Access Background Remover Plugin

This will open a new window in which you can edit your photo using the background remover. Below is a screenshot of this.

Open Background remover Plugin

Use the Mark Object tool to trace a path just inside the boundaries of the object that you want to keep in your photo. The markings from this tool will show up in green on your photo as shown in the screenshot below.

Mark Object Tool

Next use the Mark Colors for Erasing tool to trace a path just outside of the boundaries of the object. This path will be shown in red on your photo. These paths don’t have to be perfect, and it may take a little practice before you’re fully comfortable with drawing them, especially if you’re using a mouse that isn’t very precise.

Mark Colors for Erasing Tool

Now, select the Magic Wand tool and click anywhere in the background of the photograph. This will erase the background according to the marks you have made with the Mark Object and Mark Colors for Erasing tools.

Magic Wand

You will probably need to make adjustments to the Strength, Contract, and Feathering controls in order to get the best extraction for your object. The great thing about the new background remover in Paint Shop Pro is that you can play around with these controls and see what effect they will have on your photo before you actually apply the changes.

When you’re done making all of your modifications, click the Ok button, and you will be returned to the main Paint Shop Pro application with your edited photograph.

Background Changes
Hi Clark,

Thanks for the update and the link to your work! It sounds like you've found a way to handle your workflow issue.

I did write up a little more about how to change backgrounds in PSP for these types of photos - if you're interested in taking a look, the link to that new article is

http://www.brighthub.com/multimedia/photography/articles/52929.aspx

If you find some other tips, I'd love it if you'd share them with us!

Thanks again,
Michele

Chroma Key & Video Studio
Michele,
I just used Video Studio to do a Mask & Chroma Key on my photos. I used the Youtube video at http://www.youtube.com/watch?v=JLVz-f6WxQ8 to figure out how and then when I got frustrated trying to save the image that I had created I just used PSP to capture the on screen image and then saved it as a jpg file and I am done. This Mask & Chroma Key option should be in PSP since they are both Corel products. It is soooo much easier than all the hassle with the layers and incompletely erased backgrounds I was getting in PSP. I am not sure of the image quality of the final product but for my 5x7 prints onsite it will do.
I put the photos online at http://austinphoto.zenfolio.com/chromakey
in case you want to see the result.

RE: Clark
Hi Clark,

That works, too! You should be able to remove the solid background without the background remover (just using the regular magic wand tool), but your edges may not blend as well. But it definitely sounds like you're on the right path - there are a lot of different ways to remove the background, some easier than others depending on how complex the background is.

For adding the extracted object to a new background, it's a lot easier to paste the object as a selection layer into the background - then you can move it around and reposition. I think it would be easier to describe with some screenshots though, so I am working on putting those together now.

I know some of this has sounded convoluted, but I'm hoping some screenshots will clear the process up!

Thanks,
Michele

Chroma Key Delete Green background
Michele,
I guess I did it right. I just hit Layers / Promote Background Layer. I did not know how to Promote to a Full Layer. I then opened up Background Remover by going to Effects / Plugins / Imageskill / Background Remover. Once the photo was in there I just used the Magic Wand and left clicked on the mouse with the tolerance level at 26 and repeated the process on all the green areas, which kept moving around on me but finally got them to be mostly all gone. I then clicked OK and it brought the final photo into PSP where I saved it as a Gif image. Now I just need to figure out how to combine a background image with this image on top and position it and then I can save the resulting image as a jpg, I guess. Am I on the right path?
Thanks so much. I hope somebody else is getting something out of this as well.

RE: Chromakey and Color Changer
Clark,

You may want to try this for the quickest way to get rid of the background since it is completely solid:

1. Promote the background layer to a full layer.

2. Use the Magic Wand tool and click anywhere on the background - this should select the entire green area.

3. Hit the Delete key.

You should then see the transparent grid behind the image, indicating the background is invisible. You may have to adjust the tolerance level of the Magic Wand tool a bit, somewhere between 20-25.

This action would be the same as changing a color to transparent.

Hope this helps!

ChromaKey and Color Changer
Michele,
The process we have been discussing seems to be quite cumbersome to me but I am probably not grasping the exact procedure you have described. I also tried the Color Changer Option in PSP without Background Remover and that is very effective in changing the Greenscreen to White for example and does it very percisely. Is there anyway to change the Greenscreen to a Transparent Color for example? That would be very quick and painless.
Thanks

RE: Chromakey & Greenscreen
Hi Clark,

Actually, you don't have to worry about that gray and white grid - even though it is showing in PSP as a grid, that is just to signify that the background is invisible so that you don't confuse it with a white background. If you are seeing that gray and white grid, that's exactly what you want to make sure that the background is completely gone with nothing replacing it.

Chromakey and Greenscreen
Michele,
See, I got it right.
Yes, I am wanting to add a digital background image to the photo I take of the couple in front of a greenscreen. I want to be able to complete the removal of the background or make it invisible - can you tell me how you make the background invisible? There seems to be very few options in Background Remover. I see the Preference menu and I see it says transparency but when I try and use the Layers / Prompt Background option and then pick white for both of the colors on the Grid I am not getting consistant results - Only part of the Greenscreen background is turned white. Are you still talking about using Background Remover or is there another option to change the greenscreen background to transparent?
Thanks again.

RE: background...
Jamie,

There are several ways you can add a new background - instead of removing the original one, you can actually select it and replace it with a new one from a swatch or pattern. If you just want to replace a color, you can use the color changing tool - there's a tutorial on that at this link:

http://www.brighthub.com/multimedia/photography/articles/22864.aspx

Also, you can use layers to add all different sorts of backgrounds - including other photos. Here's a link to several tutorials on layers:

http://www.brighthub.com/multimedia/photography/articles/17051.aspx

I personally prefer working with layers because that gives a lot more flexibility, but it can take a little practice to get comfortable working with them!

Re: Chromakey & Greenscreen
Hi Clark,

Thanks! (And that one "L" in my name often gives me a lot of trouble. :))

I'm afraid I don't know too much about Videostudio X2, but you can make backgrounds transparent in PSP - the trick is saving them in the right format to support the transparency. JPEG doesn't support transparency so you have to save either as a PSP (or PSPIMAGE) or a GIF to prevent that "invisible" area from changing to a default white color.

I just tried a quick background removal of the photo you linked to and got better results marking the subject than just using the magic wand, although both were giving good quality and could be greatly improved with a little extra time spent. So it could be possible to come up with the right settings on the tools before the Gala and save them (or even create a script to run the process) so that you could get them printed quickly at the event.

After you remove the background are you inserting another in its place before printing?

Thanks!
Michele
