Highlight overexposure

Hi all, this is my first entry - this place is amazing!

Still learning my way around my camera and happy that such a site exists.

In this photo you can see that the hind quarter of "lucky" is over exposed.

I used F/32 to shut out the bright sunlight with 1/125 shutter and with a -2.7 exposure to try and counteract the light, the WB was at auto.

My question is how else do you manage this type of light as to save the images? ( I have done post adjustments in CS too)

Regards Sean :D

Sean,

That is one cute Jack!

The problem you're dealing with is that there is too much contrast for the sensor to handle.

In order to deal with that problem you basically need to reduce the contrast range that the image holds.

Given that it's somewhat of a tough ask to expect to be able to reduce the light output of the sun, you need to increase the amount of light falling on other parts (the shadows) of this image. Use of a reflector (get one of Lucky's litter mates to hold it for you) and direct its output towards the shadow areas, or the use of fill flash, would help address this problem.

Given that the D70's in-built flash is perfectly suited to this task, redo the shot, metering for the highlights, but with your flash turned on. Use daylight WB (-1), A exposure mode, set your flash to -0.7, and see how you go.

Sean,

Spot meter of the brightest part of the pup (the white on his side or back leg). I would have camera in manual mode and adjust aperature and shutter speed so that the meter reads +1.7 (yep, that is right). Maybe a little fill flash for his face or get him to look to the right of the lens by moving the subject of his attention

Cheers

Matt

Thanks

There is lots of information on the internet.

Try luminous landscapes:

This page is a tutorial on histograms - very helpful in confronting the type of problem you have here.

That is the cutest dog ever!! Never mind the overexposure. If you hadn't have mentioned it, not many would have noticed it...
And welcome to the forums Sean. :)

Thank you all for the suggestions.

I learnt something here:
using a reflector to bounce light into the scene or
some fill in flash.

Blending is also a method that can be used with stationary things such as landscapes etc.
(take two exposures, one for the shadow, one for the light, then blend.

Cheers
