In fact, it may be that JPEG it just used as a convenience for packaging and transferring the image data to the PC. I've cropped them to the same size for comparison (426x426), and intentionally did not adjust for the difference in original size which explains why the 450D scene is larger.Īs shown in the first table, Canon are using JPEG compression with the highest possible quality, and so the final image has very little loss of information. Here are the live view images from the two cameras. ![]() In proportion to the image size, the Nikon live view image is compressed 4 times as much as the Canon image, and this has a big impact on the quality of the final image. Just from the file sizes its obvious that Nikon are much more aggressive with their JPEG compression settings. Not just in the width and height of the images, but also in the image quality. ![]() That is, adding the ability to view the live view images from multiple camera simultaneously, and even to use a dual camera rig to view a realtime stereo anaglyphic preview.Īn interesting observation will doing this is how much the live view output varies between different cameras. One of the features I'm working on for Smart Shooter is improving how live view works.
