You can measure the noise ratio at different ISO settings in a fairly simple way and use Gimp (Photoshop) to visualise the results. Below are the results with my camera, a Pentax K7. ISO 100 is used as the basis for comparison. The Noise Ratio is a dimensionless number showing the increased noise above that of ISO 100. If you photograph a perfectly ...


Older models like the 30D simply lack the hardware required to continually read from the image sensor. These models cannot support video, except at very low framerates by opening and closing the mechanical shutter continuously. Since the introduction of live view with the 1D mkIII in 2007, Canon DSLRs have been equipped with an electronic shutter and can ...


There are some firmware (NOT by Canon. Search for "magic lantern") available which allow to turn on the video recording on camera which don't natively support it. I have not tried them, but they are reported to work on the 50D. I suppose that it would be possible for other models, too, but since it is an unsupported-"void your warranty"-DIY approach, it has ...


To prove how bad things are :) you need to set an exposure which will give a dark output without under-exposing. Use something with fine-details or a texture. Noise is always most apparent in dark regions and its effect it to destroy fine-details. To see how good things are ;) do the same with a bright exposure, without over-exposing of course. Use a ...


No. Being able to record video was an evolution in technology and it took a long time to get there. To understand why you have to first know that video is a sequence of images captured continuously at a steady frame rate and sustained over a relatively long interval. Since video would not be very useful without seeing what you are filming, Live-View is a ...


I don't see any information on a way to manually trigger the flash, however that shouldn't be necessary. Simply going to a dark area, manually focusing and taking a flash picture (at any exposure length) should generate an image where only the time that the flash was active results in exposure. The flash simply has to be a short enough period to stop the ...


I don't know of a way to do it with Aperture, but you might try playing around with Automator. It has a "Take Picture" action: This has an option to Delete picture from camera after downloading, which you would want to disable. I don't think you can avoid downloading the recently taken image with Automator, but at least you can leave it on the card. ...
