  3. Having selected the duplicate layer to go to Filter -> Noise -> Reduce Noise. A new window will open up with some sliders in it. Let’s break them down one by one.

  • Strength: This slider, affects globally. That means it will eliminate the noise pixels in the overall image.
  • Preserve details: Pixels tend to get blurred while reducing noise. The preserve details slider will bring back the texture and other small details in the image. Different combinations of strength and preserve details slider work differently for different images. You will have to experiment to see which combination gives the best quality.
  • Reduce Colour noise: This slider will reduce any floating colour pixels due to chromatic aberration.
  • Sharpen details: The blurring of noisy pixels may result in reducing the sharpness of the image. Use the sharpen details slider to restore sharpness in the image.
  1. At the end of all the sliders, you will see a checkbox that says “Remove JPEG artifacts”. This will remove any noise that may occur while saving the image as a JPEG.
  2. If you want to make noise reduction specific to the RGB colour channel, click on the advanced tab.
  3. Select the desired colour channel and make the adjustment to the strength and preserve details slider.

  6. Save your image and you are done with reducing the noise.

Now that you know the secret, try more night shots. ISO is a very good feature in digital camera if it only wasn’t for the resulting noise. Hopefully, camera manufacturers will try to come up with ways of minimizing the noise grains at high ISO but until then, this little Photoshop technique should do the trick.

How to Watermarking Images With Photoshop and Lightroom

Have you seen the writing on images? You know, the little pictures or words that show the photographer’s name? Those are called watermarks. Photographers often watermark their images so that they are properly credited for their work. Here are a few ways to watermark images with Photoshop and Lightroom.

Watermarks using Photoshop

You can create watermarks in Photoshop several different ways. Here are a few of them.

1. Text layer

The first way is to create a text layer. This is great for simple word watermarks. You can then write your name or your photography business’ name. From there, you can adjust the opacity as you see fit. Try adjusting the blending mode to achieve the look you want. To get the © symbol type; option+g on a Mac, or Alt+0169 on a PC.

2. Logo file

If you have a logo you can place it on your image. You want to make sure your logo has a transparent background. Usually, this will be a PNG file, a GIF or even a vector graphic. If you are unsure, check with your logo designer. Use the place option to put your logo on your image. Again, you can adjust your opacity and blending modes to get the desired effect.

2a. Making your logo background transparent if it isn’t already

If you have a logo file that does not have a transparent background then follow these simple steps to create one. First, open your file in Photoshop. Go ahead and unlock this layer (double-click it, then hit Enter).

Next, use the magic wand to select the background. If the background is not a solid color then select your logo image and then invert the selection. Now that your background is selected, simply cut. You can do this with cmd+x (Mac) or ctrl+x on a Windows computer.

Your image should now have a transparent background. Save this file as a.PNG (JPGs cannot hold transparency) and you’re ready to go.

3. Using the brush tool

For an even easier way to watermark, create a brush. This way you do not have to go through these steps each time you want to watermark your images.

To create the brush with the text you’ve written you will need to open a new document in Photoshop. Make sure your document has a transparent background. Type the information you want to have your watermark. Make sure you have it set up exactly like you want it on your images. Once you have your watermark just as you want it you should go to Image > Trim > Transparent Pixels. Next, Edit-Define Brush Preset. Name your brush and you’re ready to go. The same process can be done with your logo file.

You can now use your brush as you would any other brush. The key to having it watermark is to create a layer and select the brush that is your watermark. A simple click will watermark your image. You can adjust the size, opacity, and be blending mode as you like.

Watermarks using Lightroom

Lightroom has an awesome feature built-in that allows you to watermark your images upon export. In order to use this feature, you must first set up your watermark, to do that go to Lightroom>Edit Watermarks.

You can choose an image or text. There are several different settings that allow you to adjust your watermark like you want. Remember, to get the best results you’ll want to use a PNG file with a transparent background. If you don’t, you’ll have a white box around your logo. You’ll need to save and name your watermark.

For a text watermark simply write your desired information in the white box. You can change the font, color, shadow, and size of your watermark. Watch the image to see your desired effect. Use the Anchor option to adjust placement and the Inset option for further tweaks.

Make sure you use a logo file with a transparent background to avoid this white box. JPEG files do not have transparent backgrounds.

Now that your watermark is all set up, let’s apply it to your image. Go to Export and Watermarking. There you can choose whatever watermark you have set up. Your image will be exported to the desired location with the watermark chosen.
