About image enhancer

Image enhancer fixes lighting, colour and sharpness in a photograph. Use it when a picture looks flat and grey, when a scan came out too dark, or when a phone camera has left a white surface looking yellow.

Work in this order, because the steps interact. Auto-correct first, which sets overall levels and neutralises the colour cast. Then brightness and contrast, and only a little of each, since it is easy to clip the highlights and lose detail permanently. Then saturation, conservatively: oversaturating is the most common way an edited photo looks obviously edited. Sharpness last, because it amplifies any noise already present.

Be careful with contrast in particular. Raising it until the image looks punchy often drives the brightest areas to pure white and the darkest to pure black, and those pixels are gone. A more reliable approach is to lower the blacks slightly, raise the midtones, and leave the highlights alone. A good photograph is usually one small adjustment away from correct, not several large ones.

Frequently asked questions

Why does my photo look flat and grey?

Usually low contrast plus a colour cast. The auto-correct pass fixes most of it, and a small amount of extra contrast and saturation afterwards restores the intended look.

How much contrast is too much?

More than you think. If the brightest parts of the image have become solid white with no detail at all, you have clipped the highlights and lost information that cannot be recovered. Pull the contrast back until texture reappears in the highlights.

What does the warmth slider do?

It shifts colour temperature. Positive values add yellow and red for a warmer look, negative values add blue for a cooler one. Useful for correcting indoor lighting that looks too orange.

Does sharpening improve a blurry photo?

It increases apparent edge contrast, which makes a slightly soft photo look crisper. It cannot recover detail from a genuinely blurry image, and too much creates harsh halos and amplifies noise.

Can this fix a badly underexposed photo?

It can improve it noticeably if shadow detail is still present in the file. If the dark areas are pure black, that detail was never recorded and no adjustment can bring it back.

Are my images uploaded?

No. All adjustments are applied with a canvas filter in your browser.
