Gamma, resampling, and sharpening

June 11, 2014 JimK Leave a Comment

I was on a panel on raw processing about a year ago, and so was Eric Chan. At the break, I congratulated him on the big improvements in resizing in Lightroom 4. He said that the algorithms were similar; the big change was that, rather than doing the calcs in the standard Lr working space,… [Read More]

There has been a spate of posts on The Luminous Landscape about resampling for printing. A few years ago, I posted results of my own studies; you can find some of those posts here. This topic never seems to go away. Why resample before printing? Because, if you don’t, the driver – or, if you’ve got… [Read More]

Printer resampling testing with no printer

I’ve been doing all my printer resampling testing by scanning actual printed output. I think that makes sense when you trying to evaluate the complete system. It allows you to see how the resampling interacts with the printer itself, and also allows you to see what differences in resampling more important for actual printing. However,… [Read More]

As before, the test image was resampled to 360 pixels per inch before printing. The first image is from Lightroom 4 with no… [Read More]

Lightroom 4 printer resampling

September 5, 2012 JimK Leave a Comment

A while back I did a series on resampling for printing. I found that Lightroom 3 did a bad job of it when compared to QImage, Perfect Resize, or even Photoshop’s bicubic interpolation. You can see that post here. During a workshop last spring, Eric Chan said that Lightroom 4 had improved. I’ve finally gotten around to… [Read More]
