Tune image tool – how to use it for the best result (Snapseed photo editing EP1)

Sharing is caring!

This article shows you how to drastically improve the quality of any photos using the Tune Image tool in Snapseed with your mobile phone.

If you are new to Snapseed, it is a free app to edit your photos with your mobile, which has far more features available in most of the native photo editors of the mobile phone. 

In this article, I will explain how to:

  • Use the Tune Image tool, the most basic tool of Snapseed to adjust the brightnbess, contrast, saturation, and more. It is the easiest tool to use, which gives you the most results in the shortest time.
  • How to correct a tilted building with perspective tool.

To do so, you need to install the Snapseed app on your mobile, either Apple or Android. The following tutorial assumes that you already have the Snapseed installed.

Let’s get started.

What you can adjust with the Tune Image tool.

You can adjust brightness, contrast, saturation, ambiance, highlights, and shadows.

The meaning of brightness, contrast, and saturation are self-explanatory.

The ambiance setting is to adjust the contrast and saturation at the same time. I seldom use it as I like to use contrast and saturation separately.

For highlights, it will darken or lighten only the highlighted area, which means the bright spots in the photo.

As for shadows, they will darken and lighten only the shadows that are a dark area in your image. The bright area that is the highlight will not be affected.

Use the warmth setting to adjust the warmness of color. For example, you can add some cool blue color if you slide it to the left and add a warm orange color if you slide it to the right.

How to compare the before and after effect

After editing, you can tap and hold the icon at the top right corner to see the original photo and release your finger to return to the edited image.  This method is a convenient way to compare the “before” and “after” effects on the fly.

How to save your edited photo

Tap the checkmark when you are happy with the edit.

If you tap the word done at the left top corner, Snapseed will save it as a new image.

But now, I’m not going to save the image for now. Instead, I want to take you beyond the Tune Image tool to adjust the perspective of the building. 

Use Perspective Tool to straighten the image

Open up the Perspective Tool.

Pick the first option on the left to tilt the image. 

Slide down with your finger until the building is straight. Now it looks so much better. You can tap the icon at the right top corner to see the difference between before and after using the Perspective Tool.

Click the checkbox once you are satisfied with the results, and finally click the word done on the left top corner to save the image.
