Yes you can bracket. You can have the camera +/- 1/3 stop, 1/2 stop or more.
One other thing you can do with raw is to take one exposure and process it twice, once for the highlights and once for the shadows. You can then combine them together to get what you are looking for. As an example, I was shooting pictures of butterflies on bright yellow and pink flowers. The foliage was green. I shot a variety of pictures all raw. When I got them on the computer, I selected the best composition. Next, I processed the raw image to make sure that the color of the butterfly was perfect with no regard for the background or flowers. I saved that file separately. I then processed the same raw image, this time exposing it to get the background and foliage perfect and ignored the butterfly, which would have had the highlights blown out. I saved that as a separate image. I then combined both images, opening one and then pasting the other image on top making two layers. I then erased the blown out highlights of the butterfly, which was on the top to allow a more properly exposed image of the butterfly to come thru. This technique is great when you are shooting something with a lot of contract or if you are stuck shooting in the middle of the day with high sun. Steve "Brian" wrote in message oups.com... Does anyone know if you can bracket exposures when shooting in raw format? I don't have the camera yet, that's why I'm asking... Thanks, Brian |

I don't have the camera yet, that's why I'm asking... Sure. OTOH, get the higlights right and avoid bracketing altogether. ... and bracket to get the highlights right? Shouldn't have to. If you can spot meter the highlights, you should be able to avoid blowing the highlights. Works for me *most* of the time with the 7D. That way you end up exposing to the left of the histogram and losing most of the values available - clipping. In digitaland you need to be a right wing-capitialist pig to get a good profit! Have a read here http://luminous-landscape.com/tutori...se-right.shtml Also, there are techniques for combining different exposures of the same shot to 'increase' the DR. Lots of very good info on MR's site... Guess the Canon 10/20D/350D shooters are screwed. No spot meter in camera. Sorry, but you are screwy! You would not buy currently the best dslr in its class because it lacked a spot meter? Duh!

The problem with that way is that you have but one range of values to work with - if it's all you've got, then fine. It would be better to get two RAW shots: one for highlights and one for shadows. That way, you have even more to play with. http://luminous-landscape.com/tutori...es/index.shtml LCD |

I'd call that over-quantization, posterized, or under-digitized, not "clipping". Although, if you leave ACR's "shadows" slider greater than 0, it does clip shadows, and the more you under-expose at a given ISO, the more shadow range you will lose. -- John P Sheehy |

I've never understood the "two conversions" method (especially when converted to 8-bit). All it does is lower the contrast in the darker render where the other one clipped or got compressed, and mix in posterized shadows in the darker render into the lighter render. -- John P Sheehy |

It was a workaround to not being able to get the tonal response you actually needed in RAW conversion. Camera Raw 3 with the curves interface pretty much makes it obsolete. However, you didn't mix in the shadows; the idea, same as blending two different exposures, is to just use the shadows from the lighter version. -- Jeremy | |

I'd call that over-quantization, posterized, or under-digitized, not "clipping". I see, you mean it has fewer values to use rather than the ones available being cut off. Although, if you leave ACR's "shadows" slider greater than 0, it does clip shadows, and the more you under-expose at a given ISO, the more shadow range you will lose. -- John P Sheehy |

I mean if the camera can record say 5 stops and the scene has 10, then 5 of those 10 will be permanently outside the camera's ability to record. John P Sheehy |

You would have to use two (or more) different exposures to capture the full range. If the camera can record 5 stops, that's all it can record. -- Jeremy | |
