comment Why are my printed photos coming out smudged and crazy looking?
On the good side, doing it "wrong" could lead to some wildly artistic results if you're into that sort of thing. Either way, follow his advice =)

comment Shouldn't the diameter of the moon with a 600mm lens be double what it is with a 300mm lens?
Good observation on the DX->FX automatic cropping!

comment Can I repair a Nikon D90 LCD screen that has moisture in it?
Rice is actually really good, you just have to clean up the dust later.

comment How to make camera LCD show true RAW data in JPG preview and histogram?
@user1207217 I totally forgot about that after-processing part, I spend too much time with film. Thanks for the reminder for the thread!

If you're worried about exposure, is not a histogram view what you want?

comment Was there ever a photo that made people cry?
I believe that the longer something lasts beyond one frame the impact of immediacy is lost, the longer the exposition lasts you can get a more nuanced feel but also one far less striking. Note that when people talk about a great movie they quickly break it down to many wonderful scenes and then to one brilliant frame. PS: may god bless pipers of all nations, @RussellMcMahon =)

comment Why can lenses only focus from so close?
I have not seen those on a "real" lens. Outside of small, fixed focus cameras that slide a close-up lens across the front to give a near fixed focus range versus the regular infinity focus I didn't know they existed! Learn something every day.

comment Difference between luminance and brightness
Luminance is the scientific measure of how bright something is. Just like asking "what is the difference between fahrenheit and hotness."

comment Are there super-macro lenses for getting “inside”?
To get literally inside you'll need something like an industrial inspection lens, or for bigger areas maybe one of those spy cameras with the flexible stalk (those mostly seem to be video, however)? incrediblethings.com/tech/… for a crude example.

comment What is this “rushed inwards” type of photo called?
Can you give a short summation of the technique instead of just linking off-site? A quick example is what most people need to figure out how to use something like this in their own work.

comment How to get beautiful even and soft lighting on face?
Think about what's happening: when the softbox is really close the light from the edges wraps around the face because they are above and below - and the further away you move the softbox the less wrap there is and more straight light. Draw yourself a picture or use an egg and a light you can move around and you'll see it right away.

comment Did film photography have lens correction counterparts?
Rumor has it that back in the day spies used crappy tourist cameras and lenses that were mapped for distortions and then optical corrections could be applied to the photos. A similar idea to what fixed the Hubble telescope's lens problem. I'm trying to find a source document.

comment How to do jewellery photography with a telephoto lens?
+1 for focus stacking, which I was just about to mention =)

comment Does a deeper photosite increase the dynamic range?
Very true, I was thinking of the actual light sensitive part. Your description of the entire stack makes more sense for this question =)

comment Does a deeper photosite increase the dynamic range?
+1 and a side note: iirc the why is because photo detectors only work at their surface. Film, which may be what Itay is taking inspiration for this question from, does have depth but that doesn't apply here.

comment What is the metallic square piece behind the viewfinder and what does it do?
It's just a hunk of springy wire to hold the focusing screen in place. See how it's shaped, curved upwards at the sides to apply the pressure on the edges? Somewhere up inside there near the front is a little hook or latch that will hold onto that front piece of wire.
