<p>You would need 12K fps to capture telephone quality sound. Say what you gotta say, and be quick about it.</p>

<p>Video in most digital SLRs is limited to 1080p, roughly 2 MP per image at 24-30p or 60i. That might look great on a TV set, but it's barely adequate for a 4x6 print. At 60fps, you have to combine two interleaved frames, which tends to cause jaggies. The color profile for video is different than for conventional still images. Finally, the manner in which video is collected from a high resolution sensor is proprietary, and not simply the product of downsampling. This can lead to interesting artifacts in frame capture.</p> <p>Other than the Canon C300/C500, I'm not aware of any low-end cameras that capture 4K video. That said, I have a hard time matching socks, much less keeping up with rapidly changing technology. 12 bit, or "full color" (4,4,4) video is as good as it gets starting at $50K. I think I'm doing good with 10 bit (4,4,2) at 1080p. 14-16 bit is typical for high end DSLRs.</p> <p>I use frame captures regularly for CD/DVD cover photos. Fortunately the addition of text and graphics helps mask the low quality, even in a 4x4" or 5x7" cover.</p>

<p>There are third party sources for Rollei screens which are much brighter than the originals. There are several options for focusing, including a plain center, split-prism, microprism, or combination thereof. Fresnel lenses are needed to brighten the edges of the screen, even if they interfere with critical focusing.</p> <p>Most small cameras put the Fresnel lens on the back side of the screen. View cameras, including Graphlex, put it on the viewing side where it does not affect the image plane. You can buy plastic Fresnel lenses from various sources and cut them to size.</p>

<p>MacBook Pro, no; iPad, yes. An iPad is subject to abuse in normal use, whereas the MacBook sleeps completely protected.</p>

<p>Somehow the thread got diverted to cameras. There's nothing in a scanner likely to be affected by a magnetic field. Any digital device can cause interference with consumer electronics, although I've not seen it on my television or computer. If interference occurs, it can travel through household wiring or space. However, a scanner may be particularly sensitive to vibration, considering the slow, line-by-line scan. If the speaker is off, I see no problem using it to support the scanner, besides aesthetics.</p>

<p>The magnetic field is inversely proportional to the 4th power of separation. The effect on electrons in a CRT is a lot lot more pronounced than aligning domains in a steel spring or conduction in a semiconductor. That said, the magnets in floor speakers (e.g., subwoofers) are pretty large and powerful. I wouldn't store a mechanical camera or lens on top of a speaker for that reason or the vibrations. A pair of 3" speakers easily affected the color of an old CRT set at a distance of over 8". There's no effect on LCD screens.</p>

That translates to 29 MB/s, which is slower than my single WD Passport drive in USB3 (55 MB/s).</p> <p>I have a couple of 2T WD Passport USB3 drives in Case Logic semi-rigid containers. That's more than enough to collect many day's photos in the field. I take the added precaution of burning dailies on Blu-Ray discs, also in a Case Logic holder.</p> <p>I think your money is better spent transferring photos from a simple portable drive to a RAID 1/2 or DROBO 5D (or N) drive at home, which holds up to 5 3T drives with a dual Thunderbolt/USB3 interface. The DROBO is not quite a RAID, but in many ways more useful, since you can add or hot swap drives at will.</p>

<p>There is no prescribed "mountain" lens. It depends on the total effect you desire in the composition. On the whole, I tend to use a medium telephoto for mountain landscapes, in the 90-105 range (35mm equivalent), but there are many exceptions. In general, you want the mountain to fill the frame, but the foreground determines the focal length. I have groveled on my elbows to capture an alpine flower with a 20 mm lens, with Mt. Evans (CO) filling the frame. More often than not, a longer lens will establish a better balance and sense of enormity. A wide angle lens is best used to emphasize a small object in foreground, not to get it all in one frame. A lonely yellow flower a thousand feet above the treeline deserved emphasis, at least to my sensibility at the time.</p>

<p>I don't use "sneakernet" (exchange portable drives) any more than necessary. I'm more of a network person for sharing files at home, although between work stations rather than users.<br> Set up a wireless router and</p> <ul> <li>connect a network drive to one of the router ports.</li> <li>connect an external drive to one of the computers and "share" it over the network</li> </ul> <p>The wireless router connected to a modem also gives each user access to the internet.<br> Network drives come in all sizes to fit your pocketbook. I use a Drobo drive, which provides RAID security but with better scalability. My photos are also backed up to DVDs or BDs.</p>

<p>I have pretty much standardized on backpacks. I can configure a ThinkTank Airport bag to carry a D3 with a 300/4 attached, but I prefer to carry the body attached to the lens I use most - a 28-70/2.8. The 300/4 and 70-200/2.8 go on either side. The bag could be configured for a 300/2.8, if I had one. I don't routinely carry a spare body, but there's room for one with a body cap.</p> <p>A body cap is just one more thing to move around to attach a lens. There's one tucked away in the bag, but seldom used.</p> <p>My kit weighs just under 35 pounds, which is way to much for a shoulder bag. I can carry the backpack by one strap for a short distance, or by both straps all day. With a backpack, the trick is to keep it completely open or zipped shut. It's too easy to pick up an unzipped bag and dump the contents.</p> <p> </p>

<p>Howard Baker Jr. was a unique politician, who put principle over ideology. RIP. He apparently favored a Leica for snapshots around the Capitol and elsewhere.</p>

<p>The G-Loc bushing fits very loosely around the leg until tightened. The tapered plastic bushing is keyed to the collar, jams into place when tightened, and stays locked until forcibly withdrawn by the collar, even if the collar is loosened slightly. Earlier fiber bushings were split and fit fairly tightly around the leg. Aluminum legs would extend by gravity on occasions, but generally the bushings were stiff enough to keep lightweight CF legs in place.</p>

<p>Nuclear fission releases neutrons, which render practically every element they contact radioactive, including crates of camera parts used as shielding.</p> <p>Nearly 90% of the energy released from nuclear fusion, on the other hand, is in the form of fast neutrons. While you might not have to bury (or reprocess) fusion fuel elements, you eventually have to bury the entire reactor.</p> <p>Free lunch, anyone?</p>

<p>You will be fine with the 1228. I generally use a GT-1341, with a leveling platform instead of a column, but I use a G-1225(?) three section from time to time.</p> <p>None of these tripods is particularly heavy, so use a weight if you stand it on a soft surface (e.g., grass). It's always best to pre-release the mirror if you are using a shutter speed slower than 1/60 or so, and a cable release. For windy conditions, try spreading the legs to the second notch for stability. The Hasselblad makes a good wind sail (e.g., near disaster on the lake front in the Windy City).</p>
