sory for not answering erlier . thifs stole cables from phone centrale ... so i whas oit of net ...
A question about histograms: for correct exposure should the tallest spike on either end be right up next to the edge of the graph, or a few steps inside with a couple smaller spikes at the edge?
och um well .. thats loong .. Thanx goodes sombody alrdy describe it

(mahon ardy posted that if i rymember)

end yes better under lighted photo then over lighted
end ther is nothing like perfect Histogram .. as ther is no universal 1
for instance
https://www.youtube.com/watch?v=aqyjQ6-a ... re=channel
in this Vid histogram would be a high at end end begining but flat at midle as the intend of this Video is such so i s perfect fot it
so for photo .. of mini well good 1 will be the 1 thats dont run out of the histogram on one of the sides (especialy right side)
as in the article caled "Correctly exposed image" this spike on left side well that propably dark green area on the rocks , then you got hill like in mid tones end nice end slowly droping to the lights wivh meam photo is not over expoused (well it could drop iven softer so the see breeze would end whiter - butthat a risk of over exposuring)
Manual is better than Auto: Does this rule also apply to focusing or mostly just to settings?
well that depend on what firm you stuff using as is Cannon you mey stey with Auto focus as Canon got good 1
set in "central" if you can - you dont need to make sharp photo of baccground only the mini

(system of metering - "Centrral" or somthing like that (AF Central/ whole , 11 spot , 3 spot end somthing like that )
go for "Aperture Priority" in making photo - usualy you will be able to set nice field of depth without matematical knowlege how to count how time shutter to sett (well digital corection is posible ... end usualy used AP +/- button)
Light temperature: Is there a way to tell what the actual temp of the light bulbs is by looking at the writing on the bulb? I've lost the box they came in... When I look at the bulbs against a white background, they have a pink tint. I thought I remembered them being labeled as "daylight", but maybe I'm wrong!
well if they came from a good firm they wil have on them somthing like 5500k , 6000k , end so on thats light color (power) in Kelvins
ther you go again

what i would done without this page ... (well write it by my selfe ... i think

)
beside that ther is a device called light metter ... well it teal detiled data about curent light sun or artifical ... but it is separed device end a good 1 is caind of costly ..

Canon EFS 18-55mm <flower symbol> 0.28m/0.9ft. - that "kit lense " as i rymember well it will do
"EF-S60mm f/2.8 Macro USM" ... it will do better ..... if it sharps on about 25 Cm from lense (are at least 15 cm ... you whana took a picture of a mini not a Flay .. )
