Canon 7D camera evolutionary dynamic range skill sharing

Give your photographers a detailed analysis of the techniques for the evolution of the Canon 7D camera.

Key points for flexible application:

1, automatic brightness optimization and high light tone priority can only choose one use. The best way to compensate for the dark part is to use the automatic brightness optimization, to compensate for the bright part. It is preferred to use a highlight tone.

2, the use of automatic brightness optimization can be maintained in the bright part of the same time, only the dark part of the compensation. For example, in the legend, both retain the details of the white clouds, but also the shadow of the building to compensate for the brighter.

3, to maximize the expansion of dynamic range, you can use raw shooting, and then use DPP imaging. According to the case of the subject, the "High Light", "shadow" and "contrast" are adjusted.

Use Alo to show rich dark parts

(common) Aperture priority automatic Exposure (f11,1/640 sec)/iso 200/raw

Alo: Disabling

Alo: Strong

In the image that Alo is set to strong, there is no dark part in the shadow of the building under the strong sunlight, and the natural restoration does not have to sacrifice the level of the white clouds. You can see from the histogram that there is only a large change in the dark part. The ALO function is best embodied in the purpose of compensating for the restoration of the dark part.

A comparison of the 2-figure histogram shows that there is only a darker part of the larger variation, and that the brightness of bright parts, including clouds, does not change much.

The effects of Alo can also be useful in portrait photography.

Lens: EF 24-105mm f/4l is usm/aperture priority auto Exposure (F5.6,1/40 sec)/iso 800/raw

Alo: Disabling

Alo: Standard

Alo is also very effective in portrait photography. Even if you do not need to be as strong as the exposure compensation in the case, can also be smart dark poor lighting conditions prone to dark missing shadow part of the compensation is relatively bright, reproduce its texture. Compensation is not excessive and can be well balanced.

To maximize the dynamic range of the EOS 7D, you must use raw shooting and DPP imaging

(common) Lens: ef-s 17-55mm f/2.8 is usm/aperture priority automatic exposure (f8,1/400 seconds)/iso 200

JPEG Shooting data

Raw shot data DPP imaging

"DPP image Condition" Contrast:-2, High light:-4, Shadow: 3

To maximize the dynamic range of the image sensor, you need to use the "high light" and "shadow" adjustments in the DPP raw panel. At the same time, adjust the "contrast" can achieve better results. Please refer to the parameters of the legend to try.

Well, the above information is a small series of photography enthusiasts brought to the detailed Canon 7D camera evolution of the dynamic range of techniques to analyze the entire content of the sharing, you see the photography enthusiasts here, small knitting believe you now that is very clear skills, So let's go to the evolution of the dynamic range by following the tips of a small weave.
