Photography F.A.Q (Last Updated: 2024 Dec 31 10:42 am)
Subject: Light & Dark in one shot
You hit the nail square on the head with the grad filter comment. With digital it is more sensitive to the highlights than print film is, more like slide film. I would think that Misha can probably explain that better than I can. Other than a grad filter, you can do two things (and this is possibly where people will not agree with all that I say)it is possible to compensate up to 2 stops of under exposure, as there is detail recorded to work with, where as with the blown highlights there is no detail there to work with. Therefore you need to expose for the highlights, to preserve the detail, and then bring up the shadows with post work. What you do will be partly determined by the software that you have to work with. If you have curves you may be able to recover shadows with that, even better is the levels function if you have it. If you have the ability to use adjustment layers then you can select the darker area and adjust the exposure in the selected section. Even better if you have Elements 3 it has the highlight and shadow tool that will recover shadows to an extent unless it is very bad. The other method is more complex and maybe controversial. Taking two shots, one for the shadows and one for the highlights and blending the correctly exposed highlights with the correctly exposed shadows. Dont know haw much you know, so I will leave it at that for now

I have just read the article from the link by misha (thx again misha) the part about auto bracketing was great explains how to get the shots for combining - just checked in my manual and my camera does have that facility so next time ............ I shall try it :)

It's not my intention to make promotion for something special, but: for film users the dynamical range of an image is best caught by colour slide film (negative film has become better, but still does not reach slides); for digital cameras there is Fujifilms unique Super CCD SR which - simply said - has two sensors per pixel: for light and dark values, and they pretend to extend the dynamic range by 400%; actually there are essentially two camra models using this chip; test images are indeed amazing...

Is there a technique for taking shots where there is a large darker object in the foreground and the background is light? I attached a couple of examples of what I mean. I want to be able to preserve the detail in the dark areas yet not to overexpose the backgrounds. The tree image there is a larger version in my gallery or I have full size images (loads of examples- lol) if it helps. I know for conventional landscapes people use a grad.filter but in my shots the dark areas do not fall neatly into the bottom half of the pic. but in some take up one side of the frame. I would like to be able to shoot the image and have it come out the camera correct but is it possible ? Will I have to do postwork and if so what ? Thanks for any help RichardAnd every one said, 'If we only live,
