Event photographers often choose to shoot both RAW files as well as JPG files simultaneously. This allows them to have JPG files on hand for on-site slideshows or quick turnover to a client, while the RAW files are also being captured. The RAW files are used later for printing and any major editing that needs to be done. IMO Always shoot RAW, always shoot manual. Unless you can't store your raw images, then shoot jpg I guess, or just don't take so many images, or just delete the ones that aren't the best. Manual isn't that hard. It makes you think about what kind of image you are trying to achieve. It’s important to remember that the JPEG format was originally created to compress images and make them easier to transport over the Internet. JPEG is an image distribution format. On the other hand, RAW is an image capture format. It was created to give you maximum control in the digital darkroom. To get the highest quality images, this Press the Menu button and use the Main dial to select the first shooting menu tab. Use the Quick Control dial to highlight the Quality setting and press the Set button to enter the Quality setting page (A). Use the Main dial to change the RAW setting and the Quick Control dial to change the JPEG setting (B). Camera RAW is a higher quality image file that all DSLRs can shoot. To get the most from your camera, you should be using it instead of JPEG. To switch between the two formats, press the Menu button on the back of your camera. The first option is normally Image quality. Select it, and then pick the RAW option. A RAW converter will open a RAW file as it is shot using the data the camera used to make the image. This is adjustable due to it being data and not a bitmap image. So a RAW file gives a lot of latitude. A jpeg being a bitmap does not. Because it is a Canon RAW (CR2) file use DPP4 to open it. Shooting Menu 1. Image Quality: RAW (though many photographers in the target audience of the Canon T7i will shoot JPEG; see RAW vs JPEG for more) Image Review: 4 seconds (personal preference) Release Shutter Without Card: Off. Lens Aberration Correction: Off for everything (assuming you are shooting RAW; if shooting JPEG, all On) It can be useful and time-saving to change the saturation in-camera instead of in an image editing program. Adjusting the saturation is as simple as increasing or decreasing the value in your camera. You may find, after several test shots, that you prefer your images to be somewhat over or under-saturated. Here is a quick summary of how you can photograph the Milky Way: Understand the capabilities of your camera gear. Consider light pollution and scout for a dark area. Use proper night focusing techniques. Use the right camera settings. Consider foreground elements for better composition. Capture the Milky Way. Canon already embed a full size jpeg in the raw file (but more compressed than jpeg FINE). What you lose when not shooting in raw: White balance in post The ability to use a good demosaicing method (or even two methods for the same raw file) The ability to remove hot pixels by just 1 click If you want the jpeg look from camera, use DPP4.
