Exposure - for beginners/ intermediate photographers.

I just answered a question in a certain group forum, and it occurs to me that it may be useful to others. Feel free to ask any questions. So here goes: General rule-of-thumb: expose to the right. What that means, is – use your histogram and get your exposure to the right half without hitting the far right edge. Anything clipped (blown, over-exposed) will be data lost for good. The same goes for black clipping (under-exposed). The reason exposing to the right is better then to the left, is that recovering data/detail from dark areas creates noise – whereas the reverse does not. A little rule that may help you with exposure: / Sunny 16 Basically what this catchy-named rule means, is this: / Given a bright and sunny day outdoors, correct exposure for any scene will be f/16, 1/125 SS, ISO100 (also known as ASA) Working up and down with this (and your histogram displays 8 stops of light) you can adjust to suit. For example – a slightly overcast day: / f/11, 1/125, ISO100 (1-stop wider aperture) / or / f/16, 1/60, ISO100 (1-stop slower SS) / or / f/16, 1/125, ISO200 (1-stop more sensitive film/sensor) If you have a specific requirement with SS (stop motion, blur, etc), adjust the other parameters to compensate. To stop your hand motion blur, use the reciprocal of your focal length. Example: 100mm needs at least 1/100th SS. Crop bodies need to be multiplied by the crop. (ask if confused) / If your subject is moving, double SS. If you are also moving, triple it. / Of course using a tripod (and you should whenever feasible) changes this. With photography, each numerical value doubles. / ISO: 100/200/400/800/1600/3200 / SS: 25/60/125/250/500/1000/2000/4000/8000 Aperture can be remembered by using this system: / Use two numbers (f/1 & f/1.4) and double them as you go. f/1, f/2,f/4,f/8,f/16,f/32 / f/1.4,f/2.8,f/5.6,f/11,f/22 Now put them together and you have your full range of full-stop apertures :) Some cameras will list 1/2 or even 1/3 stops. Aperture effects Depth of Field (DoF), which is the distance between the closest area in acceptable focus, and the furthest. Choose your aperture to suit your subject/scene. Adjust the other two parameters accordingly. If you ever come up to a situation that has a very high dynamic range (DR) and can’t wait for better light – bracket your shots. That is, expose +/- from the above settings. You can then either decide what you like best, or even combine exposures. (ask how). Of course – if you are a street/candid/journalistic/wildlife style photographer, then you may only get one chance. Which is more the reason to learn the above. Using additional lighting such as flash is a different matter, and other rules apply. The above is a basic guide to correct exposure for everyday and natural conditions. Hope this helps some people. Feel comfortable in asking anything, or contributing.

This is the picture that is being used as the cover of this year’s Mid-Wales Tourism Brochure. On the back page it says: ‘Cover picture David Meacham’ – how posh is that? I’m proud to say that out of 90 pictures used in the brochure 51 are mine – weeeeeeehagh. Do I sound excited – you bet I am – I’ve been sitting on this for a fortnight waiting for the brochure to hit the Tourism Centres before I was allowed to upload it The doorway pictured is at Tretower Court, Near Crickhowell, Powys.

Still playing with the Singh Ray filters. I used the Galen Rowell hard-step 3-stop graduated neutral density. I stood in this this location for about an hour with gray clouds the whole time. Just when I was about to leave the clouds broke and reveled this beautiful color right before me. This was really an amazing sunset. The only thing that it needs is some livestock in the foreground.

This was a spectacular sunset. Mother Nature was for sure showing off for me. If you look to the bottom right of the photo you can see what I believe are some Kelvin–Helmholtz Instability clouds. / . / 2 shots stitched together with ArcSoft Panorama Maker Pro

I took this when I was walking on the beach with my girlfriend. 6 shots vertical. Stitched together with The Panorama Factory

I wish the camera would have let me get a slower shutter so the water would be a bit more soft but it just wouldn’t let me.

A friend of mine took me to his parents where he grew up and I must say,”that place is absolutely beautiful”. There is a creek(which you can see here)and huge redwoods surrounding it.

Taken at the ‘Super Secret Sunset Site’, this is a touch of one of the less spectacular Big Sur sunsets. The sun didn’t set on the true horizon; it set on a fog bank well offshore that was so thick it acted as solid as mountain. Obviously, fog isn’t flat so instead of getting a relatively level horizon, I got a weird blend of level and humpy, solid and semi-transparent. But the thrill was in the chase… This location is one of the most photographed sites in Big Sur, tho not as easily recognizable in this framing. The beach is pristine, the rock formations stunning and dramatic, and the sunsets… Well, for a few weeks of the year, the sun sets in a way that creates an extremely artistic vision that one MUST see to truly appreciate. The trick is to know when and how to find this place. It’s clearly unmarked. LOL! For it being as fantastic as it is and not to have even the hint of a sign telling you where it is has to be indicative of very protective residents and a tourist industry that doesn’t need this site’s exact location well known. And the season for seeing the visual miracle is short and rare on a foggy coastline. If you get it all to come together just once tho, you will know exactly what Henry Miller meant when he commented that this was what God intended for a coastline to be. About the shot – There were numerous photographer in this spot because they all knew what was possibly coming and not the sound of a casual tourist to be found. (My guide knew; I didn’t). The area closes at sunset so your window of opportunity is a bit slim to say the least. So getting set up for one of four events is the hard part and getting set up for ALL four possible events is a challenge for the serious photographers only. You need to be able to aim four ways in seconds, know the timing of the waves, know how to get your camera’s ISO adjusted to catch what you want four different ways, deal with sand so thick that the vital tripod will ruin your composition so subtly you won’t know it was lost, and juggle noise reduction (on the digital cameras). In other words, catching all four events is a task for a Master Photographer because luck won’t cut it. I gave up after about 30 minutes of flicking back and forth between shots, copying what the experts did who were standing next to me but hopelessly outgunned with gear and technique. I was missing the two shots I had a chance for and fouling up the timing on the third. The forth wasn’t gonna happen and the pros knew that but didn’t let on. The sunset was the only “easy” shot and it required ISO changes, shutter speed changes, and a great eye for colour. I knew how to do the first with the D80, I bracketed exposures for the second, and I had my guide for the third so I got the sunset and waves fairly well a number of times. The tide rushing in over the huge rocks and thru the tunnels and caves took timing I couldn’t figure out so I just shot a couple hundred shots and hoped for the best, using changes in shutter speed to capture the waves or blend them into cream. Unfortunately, the slower the shot, the brighter it gets so one must work with aperture quickly or get burned out shots between completely black ones as you over-adjust both ways since bracketing doesn’t give enough options. If you’re a professional photographer, this is your location. If you’re an amature wanting to try your hand at the really hard stuff, this is your location. If you love seeing God’s Glory exploding at you in three directions at once, enough to make you gasp from sensory overload, this is your location. If you’re a guy like me who wants it all, this location is where you will see what you’ve got to capture what the REAL MASTER laid out before you. Let it be a challenge to you.

A leaf at the eden project with bits that look like steps taken on a f1.8 lens hence the small focal point.

actually taken at night whilst trying to capture some lightning, but got the shutter speed and aperture all wrong so it came out all bright! :) and there was no more lightning :(
