Excessive grain/noise after editing in PS CS5 RAW


Recommended Posts

<p>I have a Canon EOS 450D and started taking photos in RAW and edited the photos afterwards with the PS RAW editing function. Often, the result on the "RAW screen" is good enough and I do not open PS CS5.<br /> <br /> The following happened (I edited nearly 100 photos like this, but printing them was a disaster!)<br /> <br /> Image during editing in RAW:<br>

<br /> http://i261.photobucket.com/albums/ii62/avz10/Image1-6.jpg<br /> <br /> Settings:<br /> http://i261.photobucket.com/albums/ii62/avz10/Image9-1.jpg<br /> <br /> Setting under image in RAW:<br /> http://i261.photobucket.com/albums/ii62/avz10/Image7-1.jpg<br /> <br /> Printing photo- a scan:<br>

<br /> http://i261.photobucket.com/albums/ii62/avz10/Image11-2.jpg<br /> <br /> What went wrong? Did I sharpen too much and if so, why did the picture still showed very nice on the "RAW" image?<br /> <br /> The size of most of the photos are more than 10 MB.<br /> <br /> I hope someone can help.</p>

<p>I have played a bit, did some reading and it looks as if it is the excessive amount of sharpening.<br>

This is the same picture at 119 sharpening viewed with Irfanview:<br /> <br /><br>

<p>Bringing up an exposure typically increases noise in dark areas, an effect that is magnified when you use higher and higher ISO. If you don't have a flash to use for fill, it's better to expose for your subject and bring the background down if you have to (if it isn't totally blown). When not shooting people or subjects that move, taking two exposures (using a tripod), one at the proper exposure for the background, and one with proper exposure for the subject (or more), is ideal. You can then merge the two images into one and have everything properly exposed. Bracketing is also a way to do this with people/moving subjects if your camera has a sufficiently fast frame rate.</p>
