comment image enhancement to read car plate
A look through many images using : brazil hatchback and brazil wagon does not show one like that. High rear lights unusual. Ford Fiesta like but different. May be rare. Model/brand =?

Is that line of ?holes? across the front of the bonnet standard for that model of car? I've not seen anything like that before.

Be sure to try what I've suggested. The other answers offer much that is useful re WB in general but Mr Sony has supplied a method of cheating very nicely indeed. Try it, you'll like it.

comment What defines camera's size?
Good enough question +1. Sensor size sets one limit. Real men like to carry stupidly big heavy pointless stuff so top end FF SLRs are even bigger than lens aspects dictate. Real smart smartphone users value super smallness so manufacturers mak stupidly small sensors and cram in more pixels to sound great. Alas the smart phone tablet Phablet trend messed that up BUT manufacturers see that even people who will buy a $1000 phone prefer slim sophistication over image quality so still pack in silly sensors and too many pixels.

comment After how many shots is a camera considered old?
.... My A77 repair cost was reasonable but in any case was covered by service contract ("extended warranty"). | I take "more photos than many". 'Quality AND Quantity' :-) [good theory].

comment After how many shots is a camera considered old?
Data point: My Sony A77V shutter precharge unit failed at 233,608 counts (which I was told is the usual failure mode.) The A77 counts 2 counts with dual curtain operation and 1 count with electronic 2nd curtain so actual shots between 116,xxx and 233K - so say 175,000. - :-). Real world results vary very widely for the same model - there are tables somewhere on web. Some with claimed say 100k may get SOME failures at 30k while others last 250,000k +. Really. So, need to look it up. BUT shutter replacement cost is knowable and can be factored into price. ....

comment Problem in white balancing photographs taken in sun
... (And, yes, I know we often do want to). Light at various colour temperature may fall on the black body/ Plankian locus and therefore be "white" but there is white and there is white. As I know we all know.

comment Problem in white balancing photographs taken in sun
" ... eyes and brain tuned ...". It can be argued that the actual colour changes when the irradiating source changes, as the response of the various target components to various wavelengths change. When we try to "colour balance" the image we are attempting to make it look as it would with illuminated with a standard source ("tungsten incandescent") and in fact if we look at the scene at the time the photo was taken it does not look to our eye as it would if we illuminated it with tungsten. Why should we be able to or want to modify the image in ways which do not represent reality. ...

"Because they can" is a significant factor.

comment Does camera calibration negate lens color quality?
You can wreck anything if you try hard enough but the attributes of a lens will to some extent be visible for sensible 'calibration".

comment What are the disadvantages of SLT-cameras and are they THAT bad?
In Menu item *2 / Live view display/ Setting Effect [on/off] try Off. This MAY help somewhat. When on the EVF tracks WYSIWYG alterations for eg White Balance May help with brightness level. More desperate but useful is to wind exposure compensation up - a max of 5 EVs. THEN store the correct setting to say memory 1 and bright setting to memory 2. Leave LH rotary selector on MR. To change memories rotate selector 1 click one way and back, select one step right or left for desired memory with rear thumbwheel and press selector centre button. Takes very little time indeed once burned into brain.

comment Hour long exposure of the sun
Random thought only. An intermittent super slow external shutter would allow a lower ND ratio and would at least change parameters which may (or may not) help. eg a 1s on 15s off wheel or sliding mask or ...? would be easyish to implement and should be "easily enough" made to leave no significant artefacts over the time concerned.
