Canon EOS-30D user manual

Yes, the Canon EOS 30D is considered a good camera, especially for those who are interested in advancing their photography skills. While it may not have the latest technology as it was released in 2006, it has various features that make it a solid choice.
The camera has an 8.2 megapixel APS-C size sensor, 5 frames per second continuous shooting speed, and a 2.5-inch LCD screen. It is also built with a durable body. The EOS 30D has good image quality, impressive color reproduction, and low image noise at high sensitivities.
Furthermore, it gives you full manual control over settings, making it an excellent learning tool for budding photographers. However, the camera might not be as suitable for video recording as it does not have this feature.
It's important to note that the "goodness" of the camera depends on what you're seeking. If you want the latest technology, you may want to consider newer models.

To change the exposure on your Canon EOS 30D, follow these steps:
1. Turn on your camera and set it to manual mode (M) by rotating the mode dial located on the top left of the camera.
2. Look at the top panel LCD screen or viewfinder of your camera to see the current exposure settings.
3. To change the shutter speed, press and hold down the AV button located on the top right panel of your camera simultaneously with the main dial (thumb wheel) located on the back of your camera. Rotate the main dial to increase or decrease the shutter speed.
4. To change the aperture, press and hold down the AV button simultaneously with the quick control dial located on the back of your camera near the top right corner. Rotate the quick control dial to increase or decrease the aperture size.
5. As you adjust the shutter speed and aperture, you will notice the exposure meter located at the bottom of the viewfinder displaying the changes in exposure. Aim for the center or adjust according to your desired exposure.
