Hello, I tried out the lossy DNG format with a lot of pictures.For most pictures I can't find any visible differences.But I found also some pictures with very noticible visible differences between...

Today I tried out Lightroom 5 beta.I wanted to know, whether the above behaviour of the DNG lossy conversion is still there.Unfortunately it is.

I seems this thread becomes an one man show. I don't know what is wrong with my article.Perhaps this issue is not of any interest for the other members and also for Adobe.I hoped that I can use lossy...

I thought about responding the other day, but decided my remarks wouldn't help you. And they still won't because I'm going to give you my personal opinion about lossy DNG. I don't think it is intended...

I have been thinking about your answer, Rob. Please explain a little more in detail. How do you reduce the resolution? I'm not quite grasping your answer.

Fast performance: full-rez rgb (e.g. jpeg, tiff, or dng-wrapped version of same)Fastest performance: reduced-rez rgb.Slowest performance: full-rez raw (whether dng or proprietary, whether lossless or...

Yep, it sure did. Thanks for the explanation.
View ArticleRe: Lossy DNG shows strong visible differences but JPG not, is this a bug?
Yeah, it's a common misconception that DNG is just another raw format (I'm not saying you had such a misconception), but like NEF, it can also wrap non-raw (what I call rgb) images. Many people don't...

The original raw and the smart preview look "exactly" the same to me - I cannot confirm the difference you are seeing. Related thread: http://forums.adobe.com/message/5354405#5354405

IIRC, lossy DNG is 8bit. Adaptable 8bit but still 8bit.Because it's adaptable, it can work great 99% of the times in highlight zones and in shadow zones, but probably not in zones where there are both...

View ArticleRe: Lossy DNG shows strong visible differences but JPG not, is this a bug?
I don't know that it has been ignored. If you want to work with lossy DNG thing you have to be willing to work within its limitations. If you don't like the limitations then don't use the lossy option....

The problem is the limitations aren't definable because there is inconsistency that hasn't been addressed. No one would argue that you compress to the level you're comfortable with, and everyone has...

Duarte Bruno has it right. When converting to lossy DNG the image gets squeezed to fit within 8 bits. In most cases this is unproblematic. The image in this example has very deep blacks and bright...

Interesting post, I have been using DNG lossless files for over 10 years and using DNG lossy files a lot in the last year so here is my 2 cents. I started using the lossy DNG format as lossless DNG...
