Photos with clean, white backgrounds are very popular with
- Stock offices
- Graphic designers
- Magazines and websites
The production of pure white backgrounds is necessary. A background that is not completely white looks terrible on a white page.
In this article I will guide you through a post-processing method that I use to isolate topics and give a white background.
Choose your photos carefully
Some photos are much harder to work with than others when you want a white background.
Any subject that is blurry or furry will be problematic. Like any blurred subject. Whether it is focus or motion blur, you will have trouble getting a good clean transition with the background.
Smooth, clean edges are the easiest to work with. So if you want to sell wigs at Amazon, it's hard for you. It is better to ensure that you have a pure white background that does not require post-processing with such topics.
Choose your subject and photograph it against a clear, contrasting background. If the background is too busy, isolating on white becomes more difficult.
Keep your subject at a sufficient distance from the background. Use an aperture setting that ensures that all your subjects stay sharp, but the background is out of focus.
If your subject happens to be moving, make sure you choose a sufficiently fast shutter speed to stop the movement. Making sure your subject is clear makes post-processing much easier.
Open your file in Photoshop. Make sure that this is the JPEG file with the highest resolution that it can be. Working with low-resolution images is more challenging, but larger files slow down your computer.
You have to find a balance here. If you start working through these post-processing steps and find that your computer is not processing it, reduce your photo size and start over.
Select the Select and mask tool. You can find this in the Select Menu at the top of your window. Change the View mode to an option that allows you to easily view your changes. I prefer it Overlay mode.
With the Fast selection tool, draw around the inside of your subject. Do this slowly so that Photoshop has the time to display your action.
Pay a lot of attention to the areas that you select. You do not want to have selected a part of the background. If parts of the background are selected, paint them with the Refine Edge brush.
Zoom in so that you can see better what you are working on.
When you're done and satisfied, your subject is masked, it's time to run again to the main window in Photoshop.
choose New layer with layer mask from the Output Options and click OK.
Step # 5
Add a white background by clicking Refill or adjustment layer icon at the bottom of the Layers panel. choose Solid color and put it on pure white.
Step # 6
Check the edges of your topic. Can you see one of the old background?
If you can, select the mask on your main layer in the Layers panel. Select the Brush tool and make the color Black.
Paint carefully over the areas where you can still see the old background. You may need to reduce the brush coverage and adjust the feather to achieve the best results.
If you have not done this before, it can be a challenge. But don't worry, if you delete parts of your subject, switch the brush color to white and repaint it. They will reappear.
There are various other methods and tools for erasing unwanted backgrounds. This is the best way I have found for images that are not too complicated.
Step # 7
Cut away any extra white space and save your new photo with your subject isolated on white.
This is a way to achieve a white background. As with most post-processing procedures, there is more than one set of steps that will produce an acceptable result.
Practice and experiment to find the workflow that suits you best.
