Moué ... did you see the wooden crate provided? It is typical of a "designer" sommelier equipment ... and yes it is only an accessory but an accessory of what?

You do well to notice because it is an electric screwdriver (for double left-handed?) ... which is more a gadget than anything else (a screwdriver does better).


Bof, we can see that you are young and not often on a scale. When you have more than 50 brooms, arthritis, lots of screws to put, you will appreciate. (I'm talking about TV, not TB)

With us, TV ads for Saint Nicolas toys are starting to be invasive: it's in three weeks.

Of course, Duracell is cocorico.

and not a single charger / battery manufacturer!

But that's the econological gift par excellence: that's what we offered last year to the birth of my wife's nephew!
They were surprised at first ... and then thought we were great!

Not so sure :-( I don't know of any small "batteries" that hold up ...

I would be much more positive towards "supercapacitors" which would be quite suitable for small powers, with an instantaneous reloading and a lifespan of the order of a million cycles ...

They are heavier than batteries for the same energy, but given the instant recharge, we actually need less stored energy.

a) am not so young and am quite often on a ladder (even if I'm obviously more in front of a computer ...)
b) to screw screws, there has been a brilliant invention for more than 20 years: the screwdriver with batteries (I have 3 for long days), not worth a gadget electric screwdriver much less practical and powerful. ..

About the debate on the batteries, I split this subject to: https://www.econologie.com/forums/piles-jeta ... 10144.html

: Cheesy: Well come on, finally I have my thing for you since it doesn't interest anyone!

To scan your paper documents, if you are in a hurry and want very high quality, no need to buy a professional scanner!

You just have to take the Sony A850 24 MPx (a REAL 24x36 num, at the moment at ~ 1350 € with cash back, but it should drop further next year, since a new digital FF reflex camera should arrive on the market to replace it: the equivalent at Nikon with the same sensor is the D3x, but it is worth more than 6000 roros ...). And to add a fixed lens that does not distort (the old used Minolta AF, of high flight with fixed focal length are suitable, it is the same frame) and so on!

With a tripod you have a reproduction bench which does a better job than a scanner with 500 roros.

And in addition you can use it for its main function ... and take beautiful photographs in nature or elsewhere ...

Ah ah ah Obamot what a tease !! I had understood nothing about your van, I didn't understand it much better there ...

You know scanner level, for the forum a digital camera at 80 € is enough, the proof ... in pictures:

Of course the important thing is that it is suitable. With a reflex the rendering would be more like this: ...> and if you had Bosch as a customer ... "contractual test" and at least 70 lp / mm for a "high-end" offset advertising print (i.e. over 420 dpi which is not necessary for a web page where the standard is 72 dpi => although the image quality is resized will keep its excellent characteristics in a smaller format ...).

For the flash halo hmmm ... I feel that one of these days you will still end up "falling" for "LED" lighting and following the best practices... here is another good "diversion of use". Either to equip a photo repro bench, without forgetting to combine it with the use of a tripod (although done freehand we possibly discern a motion blur , but especially a lot of "noise" and "dull" colors, especially because of a histogram not enough "to the right") it would be enough to try to realize quickly enough that it would make a very significant difference ...!
... Or, before changing equipment (for those who would be interested) ...:

How to get the most out of your current digital photo equipment
- use "daylight" lighting as much as possible.
- use the color space of your camera, as wide as possible (AdobeRGB if available)
- always work in raw + jpeg when shooting.
- adjust your "white balance" (BDB) manually "in situ" (and not once you get home, with an image processing program). Because risk of metamerism.
- never use the "auto" BDB (factory compromise between "daylight" and "tungsten" lighting) ... Because "rotten" colors are often guaranteed ...
- without image stabilizer (sensor or optics) always use a tripod for "still life". Especially beyond 6 MPx (because motion blur drift with a radius less than 1 pixel immediately reached ...).
- without stabilizer, do not forget the rule "safe speed" by multiplying the focal length used by 1,5 x to obtain the correct shutter speed, example: a 200mm "x" 1,5 => 1 / 300th of a second ...
- do not be afraid to slightly overexpose your photo, if the "main scene" is underexposed (which sometimes happens because of specular reflections, backlighting, or any other tricky light situation such as reflection flash) ...
- with a flash, use a diffuser, or change the orientation of your "cobra" by directing it towards the ceiling, if there is one ...
- with a blazing sun, use a sagex panel as a reflector, to uncover the shaded areas in the photo of people (portraits, or even small or medium-sized objects).

Image

Left histogram => underused dynamic range, non-optimized or irregular light => noise rise => frequent color fading => little room for maneuver in post-processing with image post-production software.

Right histogram => Little noise on the other hand in an image according to this example, where the histogram is well positioned, since stuck "to the right" (because the effect is to raise the BL => low lights ...).

Other advantages of adequate lighting and a well positioned histogram "to the right" thanks to an adapted exhibition => more faithful colors => reduction of "dull veil" => better "3D" effect of photos => less risk of a histogram "comb" in post-production (because less post-production ...).

Image

Photo with perfect histogram, which exploits the entire dynamic range of the sensor (there's no mystery ...)
