Focusing mode and focus:
Generally speaking, canvas prints the objects of landscape photography are mostly still objects or relatively static objects, so it is better to set the focus mode as single autofocus and focus as single autofocus.
In the available program exposure (P), shutter priority (S), aperture priority (A), canvas australia and manual (M) modes, the novice should choose aperture priority (A). This is because, in this mode, when you select the aperture, the camera will automatically select the shutter speed that produces the best exposure, while the aperture size is usually used to control the depth of field in landscape photos.
The aperture not only controls the exposure, but also the depth of field to achieve a unique effect. In order to obtain a large depth of field, the front, floating frames australia middle and back images should be clear. However, practice has proved that many brand lenses are difficult to achieve the desired sharpness and sharpness after passing F18. Therefore, it is recommended to increase the aperture setting from the minimum aperture value to level 2 or 3, that is, f13-16 is the best.
Under normal lighting conditions, it is best to choose the central key metering. However, if the scene lighting is complex and needs to take care of the whole picture tone level, the average metering method should be adopted. When metering, special attention should be paid to the choice of "point”: firstly, the subject of metering should be selected correctly; secondly, relative to the whole picture, the brightness of the subject of metering should not be too high or too low, in case of overexposure or insufficient exposure.
Whether this setting is appropriate will directly affect the color restoration quality of photos. Scenery shooting is carried out under outdoor natural light conditions, no matter it is sunny, cloudy or foggy, the color temperature will be within the range of 4500-7000k automatically corrected by the camera, so "automatic" white balance mode is generally adopted. If you want to pursue special color creativity, you can increase or decrease the color temperature to achieve a warm or cold effect.
Since the lower the speed of the image quality, the higher the noise, the more fine quality, the smoother the image transition, so in the case of conditions permitting, as far as possible to choose the ISO 50-100 sensitivity. Increase the sensitivity only if the light is poor and the tripod is not used. But try not to increase it too much, otherwise the image dark noise will increase, coarse particles, highlights will even appear "dead white". However, with the progress of digital technology, now some high-end cameras to ISO2000, the noise is not obvious.
Low saturation gives you a wider color range, more color levels, more tolerance, and allows you to record richer color and tone levels, so set your camera saturation to "low" or "soft." If the camera does not have a saturation setting, select modes such as "soften" or "normal" or "standard".
Low contrast can obtain the biggest film tone level, and then leave the adjustment room for later processing. If the camera does not have a "contrast" setting, choose "soft" or "standard" in "image optimization" instead of "landscape" or "bright".
Image quality and size:
To keep as much data as possible on your images, and to give you more room for post-processing, you should use the RAW format first. If JPEG format is used, "fine (large)" should also be selected to ensure that the image has enough pixels, and "minimum" should be set in the compression ratio menu to avoid picture quality loss.
This setting is directly related to which color space is used in digital original image collection, acrylic mounting thus determining the size of color information. Because Adobe RGB has a wider color range than sRGB, and because photos taken and processed have more layers, choose Adobe RGB over sRGB.
