Re: Your expert advice for converting TIFFs to JPGs?
- You might try this -
Open the tif in Photomatrix.
Go to 'utilities' and 'resize' to the appropriate image size for printing. (300 pixels per inch. Less and you may start seeing dots at a 'normal' viewing distance.)
Save file as jpg. (Use high quality setting. If your printer charges by the file size, or sending larger files is a problem, try test prints at lower quality settings for smaller file size, until the jpg compression induced artifacts become objectionable.)
Send to printer service.

Try opening up Lightroom and in the Library module (the one you are in when you open it up) choose IMPORT. Find your file and import it. Then with the thumbnail of your file still highlighted/selected, choose EXPORT. In the dialogue box for format choose JPG, in the finder choose a place in your files to export it or choose desktop - shoot it down the tube
and you're done with this.

- Your problem is right there. Lightroom is not something you'd use every once in a while, it is the center of the digital image management. Get a book on Lightroom if you can't figure it out on your own.On Dec 27, 2011, at 7:44 AM, Peter A. Schaible wrote:

One thing, I like NeatImage noise removal better than Lightroom's but NeatImage can be used with Lightroom.
Take some time to learn it. Well worth the effort.

highest possible quality setting. If you have a file size limitation
first reduce pixel size to a tolerable value. This depends on how large
the image will be and how it will be shown: 300 ppi for high quality
prints, 150 ppi for medium quality, 75 ppi for posters that will be
viewed from a distance. Then reduce quality until below file size limit.
This should be possible with any image editor or viewer.
