My primary targets were Spitfires and an ME109.
Photoline slc iso#
ISO 100 is because I am trying to capture prop blur at slow shutter speeds. So says the armchair expert who has never taken a picture of a helicopter that he can remember - but he sure has looked at a lot of yours and been thrilled by them.Īnd I do take a lot of pix of rooms with ceiling fans where I have to adjust the fan and the shutter to get nicely blurred blades. I have slowly accumulated knowledge of this stuff in the last couple of years from this forum and the PhotoLine forum.Īpart from the color, this just doesn't measure up as a Trevor helicopter pic, mate, you do know that, don’t you? Shutter speed too low so the rotor disappeared. When I start maundering on about this stuff, I laugh at myself. Oops - has it regained a tiny touch of pink in DPR's rendering of it? Bit of vignetting appearing, though and the center of the pic is too bright, but you get the idea. The sky has ended up featureless (but that is pretty much how it was, right?), but NOT pink. He is sitting in a pretty open situation but with some shadowing, so he should be a bit darker, I think.
Photoline slc skin#
It is still not right judging by the skin tone of the pilot. I then made the curve a bit "S" shaped, bulging up at the bottom to give more body to the darker areas, and down at the top to lighten the sky just a touch. Then went into the Curves tool, and decreased brightness somewhat. I then used the white balance tool and picked out one of the two white lines at the top of the helicopter for my white (the back of he house lower left of the helicopter is not bad too). NOT! A little OVER exposure.Īnyway, I took the lighter of the images (the first one) and opened it in PhotoLine. You lost stuff off the front of he curves. You posted one minute before I did, and with lots more info. You are shooting yourself in the foot before you click the shutter! So that is just making the problem even worse.īottom line - never use extended ISO when you are trying to protect or recover highlights. But anyway if you lower the exposure more in the RAW converter you are essentially going for even more highlight recovery in the sky.
Some force monochromatic output in highlight recovery - which happens to be great for white clouds like this.Ī little under exposed so a slight adjustment on the exposure slider should help but it takes that pink and does wicked things with it although the helicopter looks better. Open the file in Faststone and the pink sky is not anything like as apparent but the picture is slightly under exposed.ĭifferent approaches to highlight recovery. Viewing Raw thumbnails in Faststone it's apparent that all is not right and that the skies have a pink tinge. So if you force highlight recovery by overexposing a scene like this while using extended ISO then you end up with clouds that have one or more channels clipped combined with non-linear response in the unclipped channels and you'll get color disasters like this. All color processing, and especially color processing in highlight recovery, is strongly dependent on linear sensor response. Instead they use a unique gain setting that is lower than "base" ISO but the sensor response is non-linear in the upper most stop at this low a gain. Some Panasonic cameras with "extended ISO" are actually slightly different from the typical gain at ISO 200 and overexpose method of extending to low ISOs. But you are probably running into another problem here though I can't be sure. Now, highlight recovery is usually pretty OK at getting sky and clouds halfway decent as far as color goes. So the RAW converters are already doing highlight recovery (meaning they see at least one color channel clipped and are trying to recover color based on the unclipped channels only) before you touch a single slider. So the sky isn't a little overexposed, it is really, really, really overexposed in the RAW file I'm guessing. Then you focused on, and thus biased the matrix metering program, on a black helicopter. Then you added 0.3EV exposure compensation on top of that. Typically meaning the sensor gains are for ISO 200 and the shot is being over-exposed by 1 stop and then divided down in the JPEG engine on camera or RAW converter on your computer. So you are shooting ISO 100 which is an extended ISO setting.
I'd just like to know why it happens and why five minutes later in the same conditions and with similar camera settings, I don't see it. I see this every so often usually when the subject is slightly over exposed and the sky is very weak.
