Andy Crowe: I've done a quick test, and I feel like JPEGmini isn't actually doing anything. I opened the G_G_straight.jpeg file in Photoshop, used the Save For Web feature to reduce the size down to 2.7mb and compared it to the JPEGmini version. They look identical. At 100% I couldn't see any difference, and when I zoomed right in they both have exactly the same level of artefacts. The encoding is slightly different with the JPEGmini version being perhaps a touch less sharp.

It really seems like it's just saving a regular medium quality JPEG, unless the special feature is it decides what the minimum acceptable quality level for an image automatically by analysing it?

I found this comparison:

http://photokaz.com/2012/06/image-compression-for-the-web/

BEST: Photoshop Save for Web & Devices. No other optimization needed.
GOOD: Lightroom export with JPEGmini optimization.
CRAP: Smush.it. Not worthwhile for any images.

From FAQ:

What is the typical file size reduction I can expect from JPEGmini?
This depends on the resolution and quality of the original photo. For high-quality, full resolution photos produced by digital cameras, you can expect a reduction of 50%-80% in file size, while web images are typically reduced by 20-40%.

I tried JPEGmini and the file size reduction was very small. What happened?
JPEGmini achieves the highest file size reduction for first-generation photos created by digital cameras. Using photos that have been edited, re-sized or processed by photo editing software may cause lower reduction ratios.

DPREVIEW should link these excellent videos on image compression.

More than you ever wanted to know and you will truly appreciate all the effort that was made to bring you this technology.

Better test should be a high detail JPEG with lots of texture. JPEG mini should be adaptive in its approach leading to higher quality and larger file only when needed.

Anyone heard the rumors today about nikon buying all of samsungs mirrorless properties? Its still unknown if nikon will use or dump the NX mount.

DotCom Editor: That enormous red-and-white Pentax badge is not particularly attractive.

It looks better under infrared light.

Canon should at least get the "Best camera, if it was still 2008" award.

Would be nice if they let you focus stack images also like Olympus.

On article 4K video: What you need to know (286 comments in total)

"But even the best quality, '1080p' HD footage is only 1920 pixels across. 4K is significantly more detailed, since it has twice as many pixels." (twice as many pixels across?)

4k has 4 times as many pixels (in total)

1920*1080=2,073,600
3840*2160=8,294,400

On article Western Digital announces plan to acquire SanDisk (70 comments in total)
In reply to:

Mssimo: WD seems to be after sandisk's SSD business. In two years, we will have 15TB+ SSD and physical drives dont seem to be keeping up. WD spinning disks have a death date all over it just like DSLRs....its just a matter of time. Next up, maybe Nikon will buy samsungs camera business.

That is a valid point about optical viewfinders compared to electronic but I could also point out how an EVF could effectively give you night vision depending on sensor performance. Also, most people care about size and with a VF. you are not limited by the size of the mirror/sensor.
I would love a medium format size VF on a full frame camera, how about you?
The lag and dynamic range is an issue. Lag could easily be overcome by good timing on the photographers end.

Mssimo: Jokes aside, Lloyd has the best subjective write up on the new Leica SL system. Its worth checking it out and replying with your thoughts.

Quote from article "I applaud Leica for being the first company to take the logical step of building a mirrorless DSLR replacement. Which tradition-bound Canon and Nikon ought to have done two years ago."

http://diglloyd.com/blog/2015/20151020_1048-LeicaSL.html

Quote from the sony "troll"....Really sounds like he hates it right?!?

" When and if Sony can fix the few image quality issues(14 bit uncompressed raw), and perhaps add a bit more dynamic range with a Nikon D810 style ISO 64, it’s going to be very hard to argue in favor of any DSLR for 99% of shooters, including my workhorse Nikon D810."
