Does anyone have a practical guide to composition that goes beyond Rule of Thirds? one thing I'm quite bad at is composing my photos quickly and I think if I had a set of rules to learn off first I'd learn a lot faster.

Maybe I'm an idiot, but I have a question.

I just recently started shooting in RAW, but every picture seems to have a lot of blue noise in it, especially in black areas and on that longest sides of the image when I view it in light room. When I export it as a JPEG it dissapears. Is this something that happens with RAW? Is it LR? Am I doing something wrong? Am I an idiot?

Taking a guess here, most jpeg compressors have some form of noise reduction (in that the way they store color data ends up acting like noise reduction). Which can be a bad thing.
I'm probably wrong.

In Lightroom in the Gridview is there anyway to make the images load straight up I'm sick of waiting five seconds for each image to go from pixelated to fine. I tried rendering standard sized previews at 1680 but that doesn't change anything.

TBH it's easy enough to remember what kind of apertures are going to gently caress you if you aren't careful. (85mm f/1.8 at 1m? Better triple check focus)

Ha, the reason I'm doing this is I'm having subjects jump/flip INTO focus and I want to set up some lines for them to use as guides, I was thinking just having three stakes out of shot so they can line themselves up :P

I feel like a real amateur asking this but will a tele converter increase minimum focusing distance? I'm asking because I do a fair amount of cinematography on my camera and, being full frame, occasionally I'm asked for an extreme close up that I can't get with my regular lenses because the minimum focusing distance is too large. If I want to shoot just an actors eye I can't currently because none of my lenses can get that close in and still focus. Sadly I don't have the money for a macro lens so I'm looking for a cheaper solution.

(It'd also be nice to be able to use my 200mm as a ~300mm or ~400mm for those clichéd Hollywood long shots, which is why I'm not quite so keen on tubes)

The TC won't increase your MFD, but it won't decrease it either. It magnifies the image, so if you use a 2x on a 200mm lens, you'll get a 400mm FoV from the same spot. So if your 200mm is filling the frame with the actor's head, you might be able to fill the frame with the actor's eye with a 2x TC.

Keep in mind it'll degrade image quality and take away 1 stop of light for a 1.4x and 2 stops of light for a 2x (which means you lose autofocus if your lens is originally f/4 and you use a 2x, or if it's originally f/5.6 and you use either). I'm not sure how those will affect video... I guess video is a bit more forgiving than still photos.

Yeah, it's not uncommon to see teleconverters on DSLR sets, if your image is only 1080 rather than 5000 you can get away with a bit more. This more or less answers my question. Thank you.

Since the photo-business thread has disappeared (or I'm blind) I thought I'd ask this here. I was looking into theft and accidental damage insurance for my gear. I was having a chat to a rep at Aon (http://www.aon.com.au/australia/default.jsp) who come highly recommended from a friend, and I'd been informed that it was a good thing to be totally honest with my company, lest it come and bite me in the rear end. So when I was asked if this was for professional work I said yes, because I occasionally do events and work as a camera operator, and I didn't want to get in poo poo if my gear was broken during something like that.

The girl then notified me that I "needed" public liability insurance, and more than doubled my quote to factor this in, now 90% of the time if I'm on set then I'm covered by the producer's insurance and I don't see myself running a mobile studio any-time soon so why do I need it? I get the feeling the girl was misinformed but I'd really like to get this sorted so my gear's safe. Should I just say it's for personal use (which it is most of the time) or what? I live in Perth, Australia.

EDIT: Just found the photo business thread but I'll leave this here since I really need it answered.

This isn't much of a question, I know.

Do you mean mounted on the side? Because it kind of has to be there, the viewfinder is on the top and pretty much takes the entirety of the topmost face, the camera currently has it's viewfinder cover down.. If you mean pointing towards the user then I think that's the way they've got the sync->hotshoe adapter placed, not the camera's shoe-mount itself.

Been having some issues with events (parties) recently, I shoot a 5d2 with a Vivitar DF383 flash, and I'm having a higher than usual rate of overblown subjects, in that quite often the people I'm shooting will be a half stop to a stop over, It's not quite a wash out, but it leaves skin-tones overblown.
I normally shoot full manual, at whatever settings match the type of event, normally 1/50th at f4.0, with centre weighted metering, flash compensation down a stop and I normally fire the flash straight up (lots of low ceilings) with a bounce card to fill. I've experimented with partial metering (that's the JUST centre circle, not spot)but the result is often the same. My Ettl is set to Evaluative.

Has anyone encountered this issue before? I would just try using Exposure lock but the exposure flash tends to trick people into thinking the photos been taken, and as the night goes on I don't have the time to hit an extra button to expose. It's quite frustrating because no matter how low I turn the flash compensation the effect is the same.

EDIT: My flash's zoom varies depending on the time of night, it starts at 35mm when I'm doing sober portraits then widens to 24mm when the wideangle lens goes on.

Buy a grey card, put it in even light, get a DSLR, set it to spot or centre metering with the same Shutter/ISO as your Minotola, if the Minotola shows near the same fstop when pointed at the greycard then its probably accurate?

What's the usefulness of a circular polarizing filter?

I have one and it's in a mount that I can turn 360 degrees but I thought only linear polarizing filters needed to be turned? When should I use this thing and what's the procedure for doing so?

The science behind the difference between a linear and a circular polarizer escapes me, but in short a circular polarizer will cut light coming from a direct angle, say a reflection off water, off leaves or light coming from parts of the sky. You choose that angle by rotating the filter.

When you use it is dependent on what you're shooting: Forest scene looking a little too drab? Mount the filter and rotate until the reflections on the leaves are cut, making everything appear more saturated. Shooting a film in a building with lots of glass? Use the polariser to cut reflections from said glass. Sky not looking dramatic enough? If you're facing away from the sun whack it on and twist till the blues look suitably epic.

I don't think I ever shoot outside without one on!

Ones with a lower focal length. A standard lens is 50mm which roughly equates to the field of view of the human eye. A wide-angle lens (<50mm) will give you a more distorted, wider field of view than the human eye. An extreme example of this is a fish-eye lens.

edit: Wikipedia link: http://en.wikipedia.org/wiki/Focal_length#In_photography

Regarding this, one thing I've noticed is that the focal length that "matches" my open eye to my view finder eye is actually 70mm (on a full frame), almost bang on, 50mm produces a slight desynchronization between the two. Do I have funky eyes or is it because the focal plane is actually a little bit more forward than that of the eye or what?

As far as I know, PC doesn't support ttl (it's just a high and a ground so I don't see how it could, but I could be wrong). If you mean you're just trying to hook it up then you'll have to test it to see what the trigger voltage is.

I understand what PC Sync is :) what I mean is that I'd like to hook it up to my 5dmk2 for TTL, but if that fails PC sync it to my AE1, since (insofar as I know) that doesn't do TTL.

In general its useful for judging if the majority of the photo is in the correct zone. Depends, if you're shooting an extreme closeup of the face you can pretty much expose by placing the huge spike in the histo in the correct area. It's a very useful tool that can help you dodge the trap of shoddy rear-LCDs, or in my case, piss-poor uncalibrated rental reference monitors.

I was comparing the picture quality from the native camera app in my Lumia 920 with a HDR app on a desktop monitor when I noticed something. There's a small faint reddish band in the sky that looks like lens flare and then there's a much bigger red-green band that's visible in the reflection of the sky in the water but not in the sky itself.

What's this red-green band in the water?



At work with lovely monitors but from what I can tell its banding from the jpeg. Basically there are not enough colours in the gamut of 8-bit jpegs to accurately render such a graduation of colour so it ends up in bands.

I'm a bit skeptical of this explanation. Shouldn't there be banding in the sky too? Here's a portion of the original image which is a 3552x2000 JPG, as a PNG for a closer look:



Could this be a physical effect, some sort of prism-like refraction from layers of colder and warmer water?

Nope, if we're looking at the same green bands the pixelated nature of it means it's a digital issue. For reference I'm looking at the hard step from yellow to pink to green to bluish grey that's present. Banding is more present in darker areas as I think the gamut peters off towards black. This is very present in video and is one reason why DSLR video is so lovely to grade. You're out of colours. Use a format that has more :)

I have also yet to find an online or local photography club that isn't like flickr (except here). Most people are more concerned about hurting someone's feelings and offering praise as encouragement than actually critiquing a photo.

I used to think my photos were awesome and now looking back I cringe. I kind of hope I feel the same way in a year about the photos I take now, which I take as a sign that I'm improving.

I think the biggest thing for me is to critically view my own work, and it's something I still struggle with. Regardless of what other people think about your photos, what really matters is how you feel about it. For a long time I tried to force myself into a style of photography that I felt was more valued as art, and then I realised I just like taking nice pictures of people and that's what makes me happy.

It's about to fall into the archives, but I wrote a lengthy post on this subject a while back.

For me, it really helped to read some books/articles about art fundamentals like line/form and color theory, as well as photo-specific books dealing with light and tone. The idea of the components of a picture serving as linguistic elements with certain meanings resonated strongly with me. It's helped me to get out of the mindset of going out and snapping things that merely "looked cool." When I pick up a camera now, I really try to either go into a shoot knowing what I want the end result to look like in my mind's eye, or barring that, I try to compose the picture in a way that makes artistic sense with the subject matter. If you can abstract a picture into lines, forms, and colors, and if you know what the common "meanings" of those things are, you can appeal to people who are equally familiar with those things with your work or know what your picture is "saying" if you choose to bend or break the conventionally accepted understanding of what those things mean.

At this point, the hardest part of photography for me is the thinking that goes into producing a photo, not the physical act of taking the picture.
Any recommendations on the articles about art fundamentals? I feel my grasp of light and tone is at a good level, but I fall apart when it comes to composition.

Everytime someone asks about constant v. strobes I just want to take them on a set with me, point at the big rear end 2.5KW HMI pretending to be a sun and go "That's your 580EX". In terms of sheer lighting power, stills is much much easier. Flashes also generally render color much much better than LEDs, even the professional panels I'm not huge on for anything but news shooting, they're either too green, too blue or not bright enough. while there's been some jumps in LED technology over the last decade, part of the reason they've come into their own in video is more so to do with more sensitive cameras, we used to be limited to around 200-320ISO for our 'ideal' film stock and you'd probably pick a tungsten stock anyway so that lighting interiors wasn't a massive hassle, meaning anything daylight either needed to be gelled or you needed a 85 on the camera, so you were now shooting at ~50 or 100ISO. Kids nowadays with their base 800ISO Epics and BMCCS, if you're not actively sunburning your cast I don't see the point in even making a film.
