This is my first review video so sorry if it's bad quality. This video is just your ordinary review video of the Canon 600D Twin Lens Kit explaining some bas So if the exposures are say 12 exposures at ISO 400 for 20 seconds with a 10 second wait and F/5 then get 6 darks at the same. If after the first batch you change to say 12 exposures ISO 800 then again get 6 darks at those settings. Darks are easy - lens cap on, set up DSLR and interferometer, press the go button on the interferometer and put View metadata for pictures you’ve downloaded in Canon ZoomBrowser (Windows) and ImageBrowser (Mac). To turn on the copyright function, take these steps: Set the camera Mode dial to a Creative Zone mode. You can create or modify copyright information only in P, Tv, Av, M, B, or C exposure mode. Image Stabilizer (IS Mode) Image stabilization by the camera reduces camera shake in still photo shooting. It can provide effective stabilization even when your lens is not equipped with Image Stabilizer. When using a lens equipped with Image Stabilizer, set the lens’s Image Stabilizer switch to . There can be no other explanation as to why the knob will not move to Video mode. If the knob will move to "Video" but the camera stays stuck in "Sports", the prognosis is just as bad. The T3i/600D body has a used value of about $200 so it may not be economically viable to repair it. It may be better to sell the body "as-is" and use the money Canon EOS 600D (EOS Rebel T3i) DSLR equipped with a high resolution 18 MP APS-C CMOS sensor and DIGIC 4 Image Processor for high image quality and speed. The ISO range from 100 to 6400 (expandable to 12800) enables high-quality hand-held shooting in low-light conditions, without the need for flash. A 250 mm f/5.6 lens is not a telephoto lens in this context, which is why you're having difficulty. If you want to stay with Canon EF lenses, consider the Canon 500 f/4 lens, but you should consider a proper lens configuration in the form of a Schmidt-Cassegrain telescope that can support a camera. The 600D is probably best compared to the Blackmagic Pocket Cinema Camera. Like that camera it records to SD cards and is extremely affordable. Currently it has a Super 16mm crop in the most reliable current raw recording resolution. The card speeds achieved are much lower than the 5D Mark III. Therefore it does not yet record 1080p raw on the MBjFE.
