Photoshop
To transform a grey-scale photograph into a stunning blue-toned image, you can use photo editing software like Adobe
Photoshop. Start by adjusting the color balance to add blue tones to the image. Next, enhance the contrast and brightness to make the blues pop. You can also use selective color adjustments to emphasize the blue tones in specific areas of the image. Experiment with different editing techniques until you achieve the desired blue-toned effect.
