Tutorial | Defog Your Digital Pictures

Today we are going to talk about – Defogging Your Photos.

Last week we learned how to “How to Lighten & Brighten Photos“. We will be using the same photo from the previous post. So you can see as we go through the full photo editing process. Here is our original photo, along with the photo after Step 1: Lighten and Brightening.
Tutorial | Defog Your Digital Pictures in Photoshop

You might not even notice, but all digital images have a slight ‘haze’ or “fog” over them. Give this tutorial a try and you could be surprised at the amazing difference it will make in the clarity of your picture. Defogging is the process of removing the gray haze in your digital photos, making them a little clearer. This should be one of the first steps in your photo editing process, and it’s surprisingly very easy it is to do. My photo editing is done in CS5, but these similar steps can be taken in Photoshop Elements.

To start, apply the “Unsharp Mask” Filter.
Step One: Apply the “Unsharp Mask” Filter
1. Filter>Sharpen>Unsharp Mask
1. For PSE Users: Enhance (rather than Filter)
tutorial image: step one

Once you have selected the Unsharp Mask filter, a box will open up with some setting choices.

Tutorial image: step two
There are three adjustments that can be made. I personally use: 10 / 50 / 0.
Amount: 10
Radius: 50
Thresold: 0
Common Defog settings are 20 / 60 / 0 and 10/50/0. But I find the 20 / 60 / 0 setting WAY too strong – especially since we will be doing other things to the photograph later (such as color pop and sharpening). You don’t want you photo to look too extreme… which is why I personally use: 10, 50, 0. It crispens the photo just a bit, and gets rid of the fog. But try tinkering with the settings. Always play and tweak your photo until it looks just right to you. You’ll just want to stay within these levels: 10-20, radius: 40-60, threshold 0. My advice would be to use the least amount you need. Toggle back and forth between your defogged and undefogged photo to see your results!!

This technique is very subtle… but the results are amazing!

See how it crisps the lines on the sleeve and the stars on her shirt. The settings I used for my photo were 10-50-0. The difference is subtle, but as I mentioned before I don’t want to make it too harsh.

I hope this has been a help to you!

  • Leaning about defogging years ago made a huge difference in my pics! I do the 20/60/0, but then I use the fade option to go down so it’s not as harsh. Usually I’ll Fade 70%, but depending on the pic, I’ll go anywhere from 60-80%.

    i was a journalist for a couple small newspapers and used the unsharp mask all the time when i was fixing my photos for the newspaper. But, duh! i have no idea why i didn’t transfer that knowledge over to my personal digi-photos! Thanks for the “kick in the pants” superb tutorial/reminder! Excellently and concisely written!

  • Really great idea.Thanks so much for the info and great explanation. Even better I have the same software so can go with your instructions exactly to practice.

  • Awesome tutorial! I am still new to this digital stuff…….I guess it’s been a year, but I’m always learning new things! THANKS!

  • Thanks for the info – definitely a try on my next photo editing.

  • In my *Filter list on PSE9.. It doesnt have sharpen… it goes from Render to Sketch.. Any suggestions?

    • I don’t personally have PSE to check… but I’m checking with my creative team members to see if anyone uses this program. I’ll be back with any answers if I can find out for you! 😉

    • Here is an answer for you using PSE: Try looking under ENHANCE rather than FILTER. You can also use the sharpen tool in the tool tray (it’s the set of icons with blur, sharpen and smudge) if she wants to brush over certain areas.

      But for the UNSHARP MASK, she needs to do the following (instructions obtained from Adobe PSE Forum): In the Edit workspace, select an image, layer, or area. Choose Enhance > Unsharp Mask. Select the Preview option.
      Set any of these options and click OK: Amount Determines how much to increase the contrast of pixels. For high-resolution printed images, an amount between 150% and 200% is usually best. Radius Specifies the number of pixels to sharpen around edges. For high-resolution images, a radius between 1 and 2 is usually recommended. A lower value sharpens only the edge pixels, whereas a higher value sharpens a wider band of pixels. This effect is much less noticeable in print than on‑screen, because a 2‑pixel radius represents a smaller area in a high-resolution printed image. Threshold Determines how far different pixels must be from the surrounding area before they are considered edge pixels and sharpened. To avoid introducing noise (in images with flesh tones, for example), experiment with Threshold values between 2 and 20. The default Threshold value (0) sharpens all pixels in the image.

  • I have PSE and pull up the unsharp mask through the enhance drop-down like you last mentioned. It looks exactly how yours looks. I am wondering which values to use, though. The ones you suggested are quite different from information you got from the Adobe PSE Forum.

    20 – 60 – 0
    vs
    160 – 1 – 20 (or the like)

    Should the number I use be different solely because I am using PSE?

  • […] now the High Pass filter is used just as often. I personally like to use the Unsharp Mask, to DEFOG (defog tutorial) my pictures at the beginning of my photo editing process. Then I use the “High Pass” […]

  • Thanks for sharing your thoughts on photoshop.
