Taking photographs of the night sky with your smartphone can be thrilling, but managing noise in your images can present some difficulties. Especially in low light, noise manifests as grainy or speckled areas in your photos. Here are a few easy tricks to help you take shots of the night sky with less noise.


Tips to Reduce Noise:

1. Lower the ISO

The ISO setting regulates the camera’s light sensitivity. While using a higher ISO will brighten your picture, it will also add noise.

Solution: To minimise noise, keep the ISO as low as you can. Aim for an ISO of 100–400 when taking pictures of the night sky.


2.Use a Tripod

Stability: Unsteady hands can result in noisy, blurred pictures.
Solution: To get crisper, more detailed photos from long exposure shots, use a tripod to hold your smartphone stable.

3.Long Exposure

Exposure Time: Higher ISO settings are not necessary when longer exposure periods allow more light to reach the camera sensor.
Solution: Try different exposure durations ranging from 10 to 30 seconds. Adapt according to how bright the night sky is.

4. Use Night Mode

Night Mode: Many smartphones come equipped with a night mode that is intended to cut down on noise when there is less light.
Solution: The easiest way to automatically alter settings for optimal photo quality is to turn on night mode.

5.Post-Processing

Editing Apps: After taking a photograph, apps like Photoshop Express, Lightroom, and Snapseed can help remove noise.
Solution: To smooth out grainy areas without losing clarity, use these programmes’ noise reduction features.




To Sum Up

Your night sky photographs will look much better if you reduce the noise in them. You can get stunningly sharp pictures of the night sky by reducing the ISO, using a tripod, playing with long exposure, turning on night mode, and using editing applications. Have fun with your shooting!
