The importance of a calibrated display and printer
You are using a software like lightroom, photoshop or capture one to edit your photos? You love photography and you are browsing through other photos every day on flickr or 500px?
cold or warm? How should it look like?
Don´t forget to calibrate your input and output devices (your printer should match the colors seen on your display). I leave it to you to google the rest of the story. There are some well known manufacturers of calibration devices that help you to set your display or printer to the right color-levels and temperatures. Without calibration looking at photos is a kind of gambling and you may loose so much information by not seeing the images as it should be seen.
