also can anyone explain in Laymens terms the two mediums: JPEG & RAW, Thanks in advance!. PS: Do you consider the Nikon D300, To be of proffessional quality, or would you just put the money towards a new Nikon D3!.Www@QuestionHome@Com Best Answer - Chosen by Asker: ISO is an indication of the light sensitivity of the image recording medium either film or digital sensor!. Making the sensor more sensitive to light affects shutter speed and aperture settings as well as the amount of noise in the image!. http://digital-photography!.suite101!.com/!.!.!. RAW is the unproceesd image data, no exposure or color temperature corrections added!. The camera saves the sugested settings in the image but you can make the final decision later on your computer!. Great for high quality low volume shoots!. JPEG is a compressed file where the camera proces the image data and saves it in a smaller file than RAW!. Great for situations where you need to shoot alot images, such as an all day sports event !. http://digital-photography!.suite101!.com/!.!.!. Both Nikons are excellent cameras and it really depends on your budget!. The D300 would leave more for lenses and essential accesories!.Www@QuestionHome@Com The ISO rating works the same way as it would on the 35mm camera - it sets up the "baseline" from which the rest of the measurements (apparent exposure) are taken!. JPEG and RAW are different file types!. JPEG is more universal and a bit smaller, RAW is more detailed and larger!. Do not expect 35mm quality photos from any digital camera - the grain is still larger and the detail is still not as fine!. That said, for professional use, look for anything over 10 mp that has the features you want!. Personally, I like the choice of controlling either the stop or the shutter and let the camera take care of the other while manipulating the baseline a bit rich by using a lower ISO and a plus 1 exposure!. This is true for both 35mm and digital!. You could get a 35mm with a digital back and then you have the best of both worlds, but I like to carry both kinds of camera with me - 35mm for shots I may sell at a larger size, the digital for "snaps" and smaller stuff!.Www@QuestionHome@Com iso is the sensitivity to light, the more sensitive the sensor is the more noise is produced trying to magnify the light - the newer cams like the D300 do have outstanding low noise at high iso's jpeg are compressed files and low quality, RAW are uncompressed and contine all the recorded info - hence high quality - layman as i can be d300 is a fine camera yes, full frame is the future - pro anyway aWww@QuestionHome@Com |
