Highlight overexposure

Got a thin skin? Then look elsewhere. Post a link to an image that you've made, and invite others to offer their critiques. Honesty is encouraged, but please be positive in your constructive criticism. Flaming and just plain nastiness will not be tolerated. Please note that this is not an area for you to showcase your images, nor is this a place for you to show-off where you have been. This is an area for you to post images so that you may share with us a technique that you have mastered, or are trying to master. Typically, no more than about four images should be posted in any one post or thread, and the maximum size of any side of any image should not exceed 950 px.

So please do offer your critique of the images of others; your opinion is important, and will help everyone here enjoy their visit to far greater extent.

Also please note that, unless you state something to the contrary, other members might attempt to repost your image with their own post processing applied. We see this as an acceptable form of critique, but should you prefer that others not modify your work, this is perfectly ok, and you should state this, either within your post, or within your signature.

Images posted here should conform with the general forum guidelines. Image sizes should not exceed 950 pixels along the largest side (height or width) and typically no more than four images per post or thread.

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

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.

cool tips ...

Postby christiand on Wed Mar 02, 2005 7:08 pm

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
