Canon 7D camera resolution advanced skill sharing

To the photography enthusiasts for detailed analysis to share the Canon 7D camera resolution advanced techniques.

Share list:

Key points for flexible application:

1, not only in the printing of photos when the requirements of high resolution, the performance of texture or restore the exquisite sense of the three-dimensional also needs high resolution to achieve.

2, to maximize the use of resolution, use raw shooting, and then use DPP for raw imaging.

3, according to the case of the subject, with DPP adjustment "sharpness" and "noise reduction", restore its texture.

Detail in the RAW image

(common) Lens: ef-s 17-55mm f/2.8 is usm/aperture priority automatic exposure (f8,1/500 seconds)/iso 200

JPEG Shooting data

Undeniable detail image of the line is slightly thicker, but in the A3 size printing is not a problem. Even if you increase the contrast in later processing, it will only make the sharp edge more obvious, can not achieve a fundamental improvement.

Raw shooting data

DPP image Condition Color saturation: 1/contrast: 5/Noise reduction: illuminance: 0, Chroma: 0/Lens aberration correction: color aberration: On, peripheral light: On, distortion: on/Other shooting settings

The three-dimensional and brick seams of a block of bricks are clearly reproduced, very dense and delicate. The small clutter that can be seen on the image data, even when printed out in A2 size, is completely invisible.

Dense imaging reproduces a tiny focus difference, creating a three-dimensional

Lens: EF 50mm f/2.5 small macro/aperture first automatic exposure (f4,1/400 sec)/iso 500/raw

Use the EF 50mm f/2.5 small macro to shoot at the F4 near the maximum aperture. The A3 size can be printed to see the thickness of the leaves, which is the result of high resolution. The use of trustworthy fixed-focus lenses, specifically do not reduce aperture shooting, I hope that all users can feel the EOS 7D excellent imaging performance.

A2 part of Printing

A camera with a smaller number of pixels would probably make the entire leaf burn, but the EOS 7D would have a subtle focus difference, resulting in three-dimensional rather than virtual effects. In the right magnification, the gap between the slightly imaginary "A" and the focal position "B" is at a glance. Its excellent quality is comparable to a large format camera.

Another performance of the resolution--"texture reproduction"

Lens: EF 17-40mm f/4l usm/aperture priority automatic Exposure (f8,1/125 sec)/iso 200/raw

"DPP image condition" photo style: Standard/sharpness: 5/Noise reduction: illuminance: 0, Chroma: 0

Only to detect the separation of 2 lines, can not simply determine whether there is impurities, whether smooth, whether luminous and other texture performance capabilities. The legend uses DPP to show the direction and texture of the veins. High resolution can even make you feel the overlap.

About 18 million pixel of what the strength is

Recording ability

About 18 million pixels is 5184x3456 pixels. That is, when a 2-metre-long object is taken, it is possible to restore 0.5 mm of the body (1/4000). This means that when photographing a body portrait, even the hair can be reproduced in one root.

Output capacity

Generally speaking, inkjet printer can restore the resolution limit of around 300dpi. Moreover, when careful observation of the details of the photos, the human eye can see the difference between the boundaries of about 300dpi. However, the larger the size of the print, the lower the requirement for rigor, as the observation is the whole of the picture from a distance. When printing a A2 size, you should not worry if you have more than 200dpi.

EOS 7D can be imaged about 18 million pixels, so even if printed into A2 size also has more than 200 points of rigor, if printed into A3 size, you can get more than 300 pixels above the pixel. It can be said that the large print is precisely to reflect its high resolution.

Well, the above information is a small series of photography enthusiasts brought to the detailed Canon 7D camera resolution of the advanced techniques to share all the content, you see the photography enthusiasts here, small knitting believe you now that is very clear skills, Hope that the small series on the above to the Friends of the information brought to you can bring useful help.
