Thanks for the lesson in noise and sensors - - I'm a "beginning intermediate" in digi-cams, if that.  I also use PSP X.  A couple questions:

  1. Where do you filter out the "noise" as you did?
  2. How do you compress image file sizes in PSP without significantly degrading the image quality?
Thanks in advance.  BTW, I'm about to try a few pics outdoors of my Seagull!

Hi Tom,

Thanks - he is cute!

1. Noise removal in PSP:

I use the "Digital Camera Noise Removal..." dialog, can be found in the "Adjust" menu:


When changing the settings (higher number = stronger effect) you get a preview in the right of the two small windows. You can change the area of preview by just grabbing the contents of the right window with the mouse and pushing them.


2. JPG settings in PSP:

Use the "Save as..." dialog from the "File" menu. In this dialog you can change the general JPG options by clicking on the "Options" button, the following dialog will appear:


After setting your options and clicking OK, you have adjusted and saved your general JPG options. These will be used every time you save just using the "Save" icon (Small disk symbol). Note that I generally use the lowest compression (value = 1), because every saving of a JPG file with compression will degrade image quality.


In the above dialog box is another button named "Run Optimizer". This can be used to temporarily change the JPG settings for the current saving process, a preview of the loss of image quality is provided. Here again the preview area can be selected by grabbing and pushing the right image:

I nearly always use the "Quality" tab, rarely the "Download Times". The "Use Wizard" button is useless (for me), tried it once, found it unsatisfactory.

I rarely use a compression value higher than 35.
Leave the "Save Exif data" checked if you want to preserve the additional information your camera stores inside the image file (Exif data contains: Date taken, Camera settings, Camera make and model and much more - a huge amount of useful data). Uncheck this option if you save for web posting and do not want others to know what camera you have used. I save my files always with Exif data, also for web posting, because my DSLR allows me to store a copyright remark inside the Exif data.

Cheers, hope this was helpful,

Markus
