The following images are both the same frame, from Space Cowboys. The first one is slightly overexposed, and the second one, dramatically so. Look in the brown area of the satellite on the left (and elsewhere). The two images below are overexposed versions from the less expensive Optoma HD20, and below it, the Sony HW15, which is about twice the price of the HC3800.
Note that the HC3800 definitely produces blacker blacks than the Optoma, and the HC3800 image has a lot more pop and wow – a more dynamic looking image.
Below is a heavily overexposed scene from Lord of the Rings. The overexposure lets you see all the details in the shed on the right, the structure on the left, and the plants and ground along the lower right. The HC3800 offers a great amount of dark shadow detail.
