comment Can using a reflector or external flash soften harsh natural light, or just fill in shadows?
@Morpho - this is not a problem, you can control the power and softness of the light by moving the reflector closer of farther from the model and by using a bigger or smaller reflector, it's all controllable and you should play around until you get the look you want - and you probably don't want balance, balanced light is boring, interesting light has direction and shadows and often color - and if you do want balance you don't do it in direct sunlight, you find some shade.

comment What are meaningful deciding factors when deciding between Canon 5D mark III vs mark II?
@Morpho - (cont from prev comment) ... the phase detect auto focus in the 5Dmk3 with a new lens is both fast and accurate, it focuses as well as contrast detection or very careful manual focus (the focusing mistake is too small to detect) - now the 5Dmk3 does not miss focus because of the camera technology limitations, but, this only translates to better images if: 1. you had a focusing problem to begin with (if you don't shoot with shallow DOF the old system is accurate enough), 2. you have good technique (photographer mistakes cause much larger error than camera mistakes)

comment What are meaningful deciding factors when deciding between Canon 5D mark III vs mark II?
@Morpho - phase detect auto focus systems are designed to be fast at the cost of being less accurate, the camera focuses at some range around the object the focus point is on and not exactly on that object, normally you don't notice it because it's close enough and less then your DOF - but if you have a very shallow DOF you can see your picture isn't properly focused (you tried to focus on the eye but it missed and either the tip of the nose or the ear is in sharpest focus) ... (cont in next comment)

@Morpho - it means that you get smaller focusing errors - if you have problems with missed focus (and your equipment and technique are good) it can help.

@Morpho - The new focus system is still better than the old one even with older lenses (but doesn't enjoy the new accuracy improvement) most Canon lenses released since 2010 have the extra electronics to get the high accuracy, for more details visit lensrentals.com/blog/2012/08/…

@Morpho - phase detect auto focus systema traditionally trade accuracy for speed - the new system in the 5Dmk3 and the 1Dx is very fast but it's also much more accurate than older systems, older systems has a lot of variation and often miss by a bit and focus just to the front or back of the subject - the new system has a lot less variation and has way less focusing errors.

comment Why there is no full-frame lenses with leaf shutter?
What you wrote is true for new systems but you didn't address adding a leaf shutter to the established FF systems (Canon/Nikon), they both don't have the electronic connections to control a shutter in the lens - so if they decide to come up with a leaf shutter lens it will require a new version of the lens mount and be incompatible with all existing bodies - making the potential market quite small

comment Is the Nokia Lumia 1020 a suitable replacement for my aging Canon G3?
@cimmanon the G3 is a good high-end point-and-shoot, I know because I almost bought one as a second camera, it's not somewhere between a P&S and a DSLR - a DSLR is a system with replaceable parts that can be adapted to anything, it's a completely different world, I personally love it and can't imagine going back from a bag full of equipment to a simple camera - but it's not for everyone, if you want a simple camera both Canon and Nikon make really good high end P&S - and the high end Nokia phones are amazing for their size and weight (but a phone lasts only ~3 years before you need to upgrade)

comment Why don't cameras support journaled filesystems?
@strugee - I didn't say OS X doesn't have a journaling file system - I said there is no single system that both OS X and Windows can use out of the box (Windows doesn't understand HFS+ at all and Macs (by default) can't write NTFS)

comment How to price my photos to be used on someone else's website?
@Rmano - if you have no intention of going pro and this is a one time deal you can sell the images at any price, there are free on-line calculators that can give you a starting point for negotiation (and you'll probably going to negotiate down from that price). I don't like the "cut of article sold" model, as a business owner I would never give a cut of the profit in exchange for a photo (unless it's a dead product and I have nothing to lose) and I wouldn't give my products in exchange for a cut (unless it's a sure thing) giving/getting a cut isn't a fair deal unless you go in as a partner

comment Can I use ProPhoto in 14 bits?
@FriendofKim - what I'm saying is that there are two completely separate bit depths - the bit depth that should be 16bit is the one you choose in the export dialog (when you export in ProPhot/AdobeRGB) not the bit depth of the sensor - but usually you export to SRGB JPEG file anyway so it doesn't matter

comment How can I best take portraits in strong sunlight, without a flash or reflector?
... in another trip, in direct sunlight but with a bit of clouds, I tried the EC +1 and got blown highlights on the subject, so I moved him into open shade, the background wasn't perfectly exposed but it was recognizable enough for an I've-been-there photo (not my best work, but no one cared except me).

comment How can I best take portraits in strong sunlight, without a flash or reflector?
@PavloDyban - those do work, I have the pictures to prove it, but not all the time, you do have to watch your histogram and blinkies and change strategy if it doesn't work. I have used the high exposure technique successfully on a trip just 3 weeks ago - it was under direct sunlight mid-day in the middle of a dessert with no clouds (resulting in very bright sunlit areas and almost black shadows) and I used EC of +1 stop - it really opened up all those dark harsh shadows and I didn't blow the highlights at all (modern cameras are pretty good, it worked way better than I expected)...

comment Zoom Lens suggestion for hobbyist photographer
@rajaditya_m 60D+18-135 for $1000 sounds good (its cheaper than I got my 550D+18-135 a few years ago), I have the 50mm f/1.8 but rarely use it, I just don't like 50mm (on APS-C) that much, it's a taste/style thing, I like the 30mm-35mm range and when I have some free cash I'm going to buy a prime in that range (and the 70-200 f/4L for the tele end)

comment Will a low-cost macro ring flash be useful for portraits?
Does she already have a flash? I'm asking because 1. the Orbis is actually an adapter that turns a normal flash into a ring flash (and there are cheaper option available in this category) and 2. a ring flash is a bit of a specialty item, not really the most useful as a single all-purpose flash

comment What lens will fit a Canon 10D?
@MichaelClark you are suggesting it's a good idea to modify lenses in order to use them on a 10 years old digital camera body? even cheap EF-S lenses (except for 2nd hand 18-55) should be worth so much more than the body to make this modification financially unwise.

comment Is this grain normal? Canon T2i (550d) grain in high light
@MichaelClark I've edited to answer to indicate I may be wrong about ETTR effecting image quality, I'll try to find more information (and maybe even do some experiments) later

comment Is this grain normal? Canon T2i (550d) grain in high light
Noise is about the amount of light hitting the sensor, not ISO, I've added two examples to my answer, my 550D (T2i), "crappy" kit-quality lens, ISO 400 with no noise

comment Is this grain normal? Canon T2i (550d) grain in high light
@ChinmayKanchi - I'm not sure, I don't remember exactly and can't find the original source, I think it was something about color accuracy or saturation. I personally don't care much about ETTR because I don't like to spend time editing so I didn't really care about the details at the time.

comment How to explain to your client that a camera flash does no harm to infant?
@Caleb - that's what I said - you SHOW them you respect their concern, you make a big show out of it, you tell them you are doing all those things to protect the baby that you would have done anyway to get a better picture - you do NOT try to convince them using rational arguments and evidence, you do not argue with them -- you make them feel you are going out of your way to address their concerns (while doing the exact same thing you would have done anyway)
