Default FZ10 Sharpness Setting

Does setting the FZ10's Sharpness to HIGH do anything that Photoshop can't do in postprocessing? The manual is vague to say the least.

Default FZ10 sharpening settings

The camera applies the 'Picture Adjustment' settings (contrast, sharpness, saturation) before lossy-compressing the image into a .jpg fle, so it can work with all of the original information it captured from the CCD. A computer-based image editor (e.g., Photoshop) can only work with the information in the .jpg file.

Whether you do the Picture Adjustments in the camera or in PhotoShop, you will be losing some information, but hopefully gaining a more satisfactory appearance.

So, the camera can work with all the information its CCD captured, but must do so within the time and computing constraints of the camera. PhotoShop offers more flexibility and probably superior algorithms, but is starting with an already degraded (.jpg) image that may have lost additional information when the camera applied the 'Picture Adjustments' and possibly EV boosting that can blow out some highlights.

One way to decide which approach you prefer is to take photos of the same scene at each of the three sharpening levels. Bring them into PhotoShop and sharpen the Low & Standard ones, then compare the result with the original Standard and High images.

I always shoot with minimum sharpness and contrast. If you do any image editing you should sharpen last and minimum contrast gives you the most exposure latitude. Of course the images donít look that great from the camera but you can set up an action in Photoshop to batch process them for normal viewing and keep the originals for advanced image editing.

Since sharpening targets the high frequency content of the image, doing so in low light can produce more visible noise. Personally I prefer setting Sharpness (detail), saturation and contrast to the lowest positions. The difference between the lowest and highest settings is such that many people might say they see no difference.

Yet, in low light situations it could make a great deal of difference to an "educated eye."

I somewhat agree that if the visible image needs to be sharpened for viewing on a monitor I prefer to do it with the software of my choice.

Bob,

Does the "picture adjustment" of the FZ1 equivalent to setting all three paremeters on the FZ10?

Thank you,
Alex.
