1) WHAT IS DPI?
Screen resolution is in PPI, pixels per inch. You know DPI is Dots Per Inch. A pixel can be made up of many dots, so that’s why pixels on screen are 72 to 120 pixels per inch.
FOR PRINTING, a printer uses DOTS. They are expressed as DOTS PER INCH (DPI) resolution. Because many dots can go into 1 pixels, printer resolution is higher, 200 to 300 dots per inch.

2. Can I enlarge a small picture to print a bigger one?
Yes, with software such as ON1 AI or $80 Gigapixel AI to improve feathers/fur texture and detail.

Can you think of other software programs you use?

B) Try free software like Lagom ( http://www.lagom.nl/lcd-test ) Best Results monitor calibration tool called color calibrator or colorimeter Spyder or Xrite i1 Studio https://www.xrite.com/categories/calibration-profiling/i1-solutions

4. What is a printer profile?
A custom profile for your printer, paper, ink and printer driver. The profile does not come with your printer. You can download them, but know you must use the specific paper and ink specified in the profile.

5. What is color management? The path from camera to computer to final print. Each device has its own color profile which describes color using a standard color space as a reference. Color-managed software uses these standardized profiles to translate color from one device to another (Like Chinese into English). It uses a Color Management Module (CMM).

6. Black and White: Shoot RAW. Use a BW printer profile in Lightroom. My method is to adjust the monochrome image in Lightroom’s Black & White Panel.

7. Which printer are you using for your home?
DNP 820a dye diffusion (dye sub) printer. It’s reliable. It can be left for months and does not dry out. It uses heat, transferring dye from 3 colored ribbons onto paper that is up to 8 x 10, or panorama format.

8. Inkjet Frustration: Q: Jim I’m having problems with my Canon/Epson printer when ink cartridges clog.
A: Find Jose Rodriguez on Youtube, watch Jose's tutorials on cleaning your clogged ink jet printer heads https://www.youtube.com/user/cheo1949/videos

9. Where are good online sites to order color managed prints ? Shutterfly.com (BOGO’s Deals), BayPhoto (metal, epic, canvas high quality). For books, I use Blurb, with a preloaded ICC profile. For art prints, Printique is reliable https://www.printique.com

10. What is SOFT PROOFING?
To save ink, paper and time, use your monitor like a flight simulator, simulating the combined effect of screen, ink and paper. A Soft proof temporarily simulates how your photo will appear on another device, such as a printer, by using only a computer monitor. Calibrate your white point to paper white. Use a quality ICC Profile. Use a meter measurement device to create your printer profile. https://www.cambridgeincolour.com/tutorials/soft-proofing.htm

Q: Jim can you say more about the ON1 "No Noise" software you used in your demo? Like, how does it compare to Topaz?
