## Overview

Easily adjust the exposure of your photos to correct lighting issues or achieve a specific aesthetic. This tool simulates camera exposure compensation, allowing you to brighten underexposed images or darken overexposed ones with precise control over brightness and contrast.

## Inputs

- **Image File** (file): Upload any image file (JPEG, PNG, WebP, GIF, BMP, TIFF) to adjust exposure
- **Exposure Compensation** (range): Exposure compensation in EV stops (-3.0 to +3.0). 0 = original, positive = brighter, negative = darker
- **Output Format** (select): Choose output format or keep original. PNG recommended for maximum quality
- **Quality (1-100)** (number): Output quality for lossy formats (JPEG, WebP). Higher = better quality but larger file size

## When to use

- Correcting photos that were taken in low-light conditions and appear too dark.
- Fixing overexposed images where highlights are blown out or details are lost.
- Adjusting the overall mood of an image by shifting the exposure levels before saving in a preferred format.

## How it works

- Upload your image file (JPEG, PNG, WebP, GIF, BMP, or TIFF).
- Use the exposure slider to set your desired compensation in EV stops, ranging from -3.0 to +3.0.
- Select your preferred output format and quality settings if you wish to convert or compress the file.
- Process the image to apply the changes and download your adjusted photo.

## Use cases

- Recovering details from underexposed smartphone photos taken indoors.
- Reducing brightness in outdoor shots to bring back color depth in highlights.
- Standardizing the brightness levels of a batch of images for a consistent look.

## Frequently asked questions

### What does the exposure compensation value mean?

The value represents EV (Exposure Value) stops. A positive value increases brightness, while a negative value decreases it.

### Can I convert my image to a different format?

Yes, you can choose to keep the original format or convert your file to JPEG, PNG, or WebP.

### Does adjusting exposure affect image quality?

Adjusting exposure is a digital process. Using high-quality output settings like PNG or high-quality JPEG will help maintain the best visual results.

### Is there a file size limit for uploads?

Yes, the maximum file size for image uploads is 10 MB.

### What is the recommended quality setting?

A quality setting of 95 is recommended for a good balance between visual fidelity and file size for lossy formats like JPEG and WebP.
