Why does DSLR camera say subject is too dark

Hi guys! We’ll talk about why a DSLR camera may say the object is too dark. Photographers often experience this in dim light, and it’s really annoying. But knowing the origin and how to fix it can save you loads of time.

Let’s get into it and learn more!

What is the “Subject is Too Dark” Error?

“Subject is Too Dark” – this alert on your DSLR camera means that the camera can’t focus properly. It requires more light to get sharper images. Low light photography is a challenge when using a DSLR. Too much brightness causes overexposure and too little causes insufficient lighting for focus detection.

If you don’t have additional lighting sources, you may want to raise your ISO settings to allow more light into your camera sensor.

Causes of the Error

Ever take a pic with a DSLR and get the message, “subject too dark”? Frustrating!

Trying to get the perfect shot? This article will let you know what causes this error and how to resolve it.

Low Light Conditions

In dark lighting conditions, photographers face a challenge. Trying to capture images of people or other moving things can lead to underexposed photos, even with the best camera settings. The reason is that DSLR cameras can’t shoot beyond a certain shutter speed-aperture combination. Longer exposure time and higher ISO settings may not be enough.

To get the best results, supplemental lighting sources like diffused flashlights and LED panel lights can help. They have adjustable brightness and color temperatures. Also, wide apertures combined with higher ISO settings let more pieces of available light into the frame.

Exposure Settings

When your DSLR camera says the subject is too dark, it means the exposure settings are incorrect. This could be due to several factors.

If you’re shooting in Manual Mode, check the shutter speed, aperture, and ISO are correct. Also, make sure the white balance setting is accurate for accurate colors.

If shooting in Auto mode, be careful with the exposure compensation values. Don’t make drastic adjustments; subtle changes work best.

Under/Overexposure warning indicators or Live View can help you get the correct exposure. External sources like other cameras or light meters are also useful. This way you don’t have to guess based only on what you see in the viewfinder.

Camera Settings

When your DSLR camera displays a message saying the subject is too dark, it means not enough light is entering your camera lens. There are several reasons for this error that can be adjusted or avoided.

The most common reason is incorrect camera settings. Check the ISO, shutter speed, and aperture to make sure they are suitable for the shooting conditions and subject. For example, a higher shutter speed is needed for a fast-moving subject to prevent motion blur.

The ISO and aperture can’t be too high or there won’t be enough light. Balance all settings with exterior light levels and desired motion effects before taking the shot.

Another issue can be dirt or sand/dust in the lens or its connection to the body. Over time, dirt can accumulate, blocking some light and making an under-exposed image. Keep both components clean and check their seals.

Finally, remove any filters from the lens if they are not needed. Otherwise, they will reduce the amount of light getting into shots, leading to dim pictures.

DSLRs proclaim “too dark” when there’s not enough light in the scene. We’ll investigate how to brighten the subject – camera settings and measures to take. Let’s dive in! Solutions to explore!

Increase ISO

ISO stands for International Standards Organization. It measures the sensitivity of light that affects a digital SLR camera’s image quality. To take a photograph in low light, you may need to manually increase the ISO. More light will be captured on the sensor, allowing a brighter photo. When increasing ISO, noise or grain may appear.

If your camera says “subject too dark” when trying to take a photo, increasing ISO will help. Locate and adjust the ISO setting on the camera’s control panel or menu. The value for this option can range from 100 – 800. Try different settings to find the best one for the lighting and desired effect!

Change the Exposure Settings

When your digital cam has a dark image, there is usually an easy fix. Usually, this is done by adjusting the exposure settings on the camera. Doing this helps the camera use a longer shutter speed, so more light can get to the sensor when taking a shot. This keeps the details and prevents shadows.

If the manual exposure doesn’t work, use exposure compensation or TTL metering. This lets you adjust the light before taking a photo. You can also make parts of the image brighter or darker.

For night shots or dimly-lit environments, increase the ISO setting. This may create a noisy picture, but it keeps the image from being too dark.

Use a Flash

A flash is the easiest way to make pictures brighter, especially when you are inside. It will help the light bounce off surfaces, like the ceiling, and give a gentle glow. If you can, use a reflector card or wall to brighten the light even more.

Using the flash takes practice, but it is worth it for great pictures. Also, if needed, you can change your camera’s shutter speed and ISO to get the perfect exposure with the flash.

Tips for Avoiding the Error

Subject Too Dark is a common issue with DSLR cameras. It happens when the camera’s exposure value does not match the light on your subject. Here are tips to avoid this mistake and take amazing shots each time:

  • Expose for Highlights: In Manual mode, set the exposure so most of the highlights will fit in a good range, but some parts can be slightly above or below middle grey.
  • Use Aperture Priority Mode: Pick an aperture that allows enough light in.
  • Check Light Meter: Check the reading the camera meter is producing and adjust it before shooting.
  • Use Exposure Compensation Feature: When in Aperture Priority, this feature lets you increase or decrease exposure by two stops.

By following these steps, you can avoid Subject Too Dark errors and take great photos!


A DSLR camera might say a subject is too dark. It can’t see it properly. The metering system may be wrong, so the settings are wrong too. Solutions? Raise ISO, increase the shutter speed, and increase exposure compensation.

Tips? Use a tripod and diffuse light. All these should help get the best image, even if the subject is too dark.

Summing up, when your DSLR camera says the subject is too dark, it means more light is needed. To let in more light, try to: Increase the shutter speed, widen the aperture and boost the ISO. You can also use flashes or reflectors to brighten up subjects.

By understanding and applying these techniques, you can get excellent results with your DSLR photography.
