Converting RAW to JPEG in Silkypix

I recently installed the full trial version of Silkypix and last night I attempted to convert a RAW image into JPEG and the menu gave 3 options.

I've already got the ebook for Silkypix but can someone explain in more simple terms the differences between the three JPEG options and which is the better one to save JPEG's onto

I save my JPEG images onto an external hard drive as a matter of course but sometimes I also save them on a CD/DVD for friends and family, etc.

Also I couldn't find how to delete the images in Silkypix when they are displayed, I have to go back to the pictures folder on my PC. Am I missing something here?

Regards

Rob

As i remember there is not an option for deleting images in Silkypix.

After you have processed the raw image select "close". If you want to delete the image do that in windows or whatever else you use to organise your photos.

This might help with understanding the different jpeg options:http://www.impulseadventure.com/photo/chroma-subsampling.html

Yes you can delete images in Silkypix. In the thumbnail view, click the image(s) you want to delete, then select Delete Selected Scene from the File menu or press Delete.

I recommend keeping and backing up your RAW files as well as JPEGs. You might want to rework some of them in future, or convert to a new format, or print directly from them or whatever. It's like keeping your negatives.

For best quality JEPGs, use YCC444 at 100%.

The Silkypix software manual explains:

Exif-JPEG (YCC422)

This is a JPEG file including the EXIF information which has 2 pixels of color information per 4 pixels of lightness information.
This is the most popular format. Because only a half of the chroma information is recorded, the compression ratio becomes higher, however, color separation degrades at a fine area.


Exif-JPEG (YCC420)

This is a JPEG file including the EXIF information which has 1 pixel of color information per 4 pixels of lightness information.
The chroma information is recorded less than YCC422 described above. Therefore the size of the file becomes smaller but the image quality degrades more.


JPEG (YCC444)

Because all chroma information is recorded, the size of the file becomes larger and the degradation of the image quality is less.
You can attach the EXIF information into this JPEG file if you check the "Recording Exif-IFD" checkbox.

* JPEG YCC444 format is not prescribed in the Exif Standards.

Thanks for correcting me regarding the deletion question. I have never used it, and didn't think it existed.

Thanks for all your advice and explanations, saved some this morning with no problems.
