On article Amazon reveals thinner Fire HD tablets (66 comments in total)

Stop referring to permanent storage as Memory, and instead call it storage. You are simply perpetuating confusion for people who are barely computer literate.

On article Behind the Shot: Crystalline (46 comments in total)

A wonderful article that goes into detail about how it was captured as well as the post-processing details. It''s a delightful change from regurgitation of specs and routine testing.

We need more articles of this type from which newer and even more seasoned photographers can really learn from.

Thanks !


Just disregard the avalanche of nitpickers and loudmouth jaded pessimists who must inject their irrelevant nonsense rather than appreciating a wonderful photography tutorial on a specific image.

This is clearly optimized for video so the most important question is does it have overheating problems of the prior model when shooting at highest 4k rates.

Thanks for the links.

MustyMarie: Title is very bad, as being 'dumped with' implies the person is IN the stuff being dumped, he was 'dumped ON'.

Which has happened when water was being scooped up from a lake and actually got a person IN the water, of course he drowned - Darwinism I believe is the cause !! ;)

It's not Darwinism...it's Drownimism !!!

I would be far more interested in getting the 3D model data than to have the figurine. That way you could use your own 3D software (e.g. Maya, AutoCAD3D, or even the free DAZ Studio, Maya etc.) to modify the pose of your character, use the character in a virtual environment of your choosing, and even make a CG movie.

At some point when higher res 3D printing becomes more affordable you could at that point create a mannequin. This would of course assume, that the 3D data is in some standard form, that you could import into your 3D software program.

PS Check out the technology in DAZ Studio which is free (Windows or Mac)

Jim Evidon: Back in the good old days of rocket research, we used to rely on a high fps rate camera called a GSAP to study rocket engine firings. It's total running time was a matter of seconds. It cost a fortune then.

Now there may be one for less than $700? What possible use can an amateur
photographer have for such a device once he has taken a picture of a hummingbird in flight or a bullet shattering a light bulb? It's a marvelous achievement in price vs. performance, but it's long term use to the average photographer will be in bragging rights only.

Someone said he'd pick one up in a heart beat. And do what with it? Do you have any idea how quickly it will fill a 32GB card at 18.500 fps @ 2560 x 2048 pixels per image? I would imagine we are talking in terms of seconds.

It has a profound scientific future and I cheer for the inventor, but aside from that who in amateur photography needs it? Who will want one is another matter.

Some people may use it for Art !

I have seen some amazing photos with swirls of water and splashes that was truly beautiful superimposed on dancers for example.

One should never underestimate artistic creativity.

maxnimo: What we should be striving for is 240 fps video on true 240 fps monitors. The result would simply blow you away.

You are confusing spatial resolution with temporal. The visual system does not change with improvements in technology.

MediaDigitalVideo: What it the best relation between number of fps and shutterspeed to get the best quality out of every videoframe.

For one, amount of light is a major factor since with very short exposures, you get less light.

Single shot is fine when you can trigger the time of the shot, but not when you want to see a sequence such as water balloon, or some other event. With multiple frame (video) you are guaranteed the ability to pick the most interesting set of frames even if you just want a single frame. Hence, for many applications the multiple frames of video are a better choice of tool. You can always not use multi frame if you wish, but a single shot device does not give you a choice.

Excellent presentation without any BS, or eardrum shattering loud crappy music. Just the facts.

I also think it is very well designed from the customer viewpoint:

1. Use your own lens
2. Power supply is easily available standard USB type battery / charger
3. LCD screen is built in
4. Various models available with increasing pixel and speed resolution to fit the buye's needs and budget.

Overall an excellent idea, design, and marketing.

On article ACDSee Pro 8 and ACDSee 18 announced (53 comments in total)

I had used an earlier version of the basic ACDSee image managers but got sufficiently annoyed because they would not update their RAW converters database once a newer version became available, making the one I purchased useless for working with newer cameras.

The RAW converter updates were freely available to download but would not work with the no longer freshest version. It was not a technical compatibility issue, but a business decision.

Sure I probably could have used the free Adobe DNG but that would have involved a lot more time.

It turns out that programs such as the excellent free FastStone Image Viewer/Manager (or XNView) continuously upgrade their RAW converters so you can always view RAW images from the newest cameras.

FastStone is extremely fast, with a great interface and does some very good basic image editing. I would rather donate money to these programs than to keep having to purchase ACDSee annually or purchase a subscription.

DonnaRead54: While the law may be on Wikipedia's side, the goodwill certainly isn't. The photographer made the trip to Indonesia, took his gear, found the monkey and almost lost the camera. Without the photographer, Wiki wouldn't have jack. How rude! And l_d_allan has an excellent point! Do photos taken using a motion trap not count as copyrighted material either? After all, the photographer didn't 'really' take the shot. And to cite NG as an example is dead on! I'm surprised at the lack of integrity that Wiki showed us here.

Not Wikipedia!!

audiobomber: The photographer should have explained perspective to the apes when he handed over the camera. The wide angle closeups make them look silly.

Wikipedia should not hide behind the law. They are not subject to any one country's laws, so they should be guided by ethics. The photographer owns the photos. It was his camera, he brought the photos to the world, he owns them.

It's Wikimedia, not Wikipedia -you might want to correct your comment.

On article Panasonic Lumix DMC-FZ1000 Review (902 comments in total)
In reply to:

forpetessake: If you want a superzoom, just get any lightweight Nikon/Canon DSLR and attach an 18-200 zoom to it and it will be ahead of this Panasonic in every way. Or if you want a mirrorless camera, get a Sony A6000 with 18-200 zoom, or Samsung with 18-200, or Olympus with 14-150.
Only those who are interested in half baked 4k video may find this camera interesting.

First of all the video may not be as good with the DSLR's


Second a really good 18-200 will be very expensive and certainly slower and probably of lower quality.

However, for still pictures I would have to agree with you, the APS-C stills will be much better quality and low light sensitivity will be incomparably better.

On article Travel tripods: Comparing 5 aluminum kits (112 comments in total)

A quick query about small, high quality video heads, that would fit these lighter travel tripods.

Has anyone had any experience with such video heads for a camera such as the Panasonic GH3 or GH4 which weighs under 0.68 kg (1.5 lbs) with a zoom lens ?

On article Travel tripods: Comparing 5 aluminum kits (112 comments in total)

An excellent review far more detailed and professional than the usual DPreview job.

I had purchased a heavy duty aluminum Gitzo tripod and the concentric leg locks took more time and effort to set than the lever locks that I kept seeing.

I envied the Manfrotto lever leg locks, until the plastic leg locks on a cheaper Manfrotto tripod broke and the tripod became totally useless and pretty much un-repairable. It got very little use and I'm guessing age was the primary cause. I had another cheap no name tripod fail the same way, although it lasted a much much longer than the Manfrotto. Now I understand why the concentric locking mechanism (almost always metal) is far superior even though, without fast screwing feature, it takes longer to tighten and loosen.

I would personally always stay away from any lever locking tripods and I now fully appreciate the Gitzo concentric metal leg locking mechanism.
