Hello TN Members,
I am a novice photographer and use Canon Powershot SX130IS.
I have been facing a chronic problem.Suppose I am taking photograph of a Butterfly which is resting on white flower.Bright sunlight on flower.When I take picture I notice the flower looks overexposed.If I change setting then flower looks better(not overexposed),but subject(Butterfly)gets very much darken.
Wish you can show me the right path,
Kind regards,
Srikumar

Hi Srikumar,

There may not be a right path. What you described looks like you are dealing with a difference between shadows and highlights that your camera cannot cope with. Say, the difference between shadow and highlight is 100 where shadow is 0 and highlights 100. You camera may have a dynamic range of 75. So if you move to the shadows you will have overexposure, and if you move to the highlights you have underexposure.

To only solution may be that you need to make photo with less difference between shadows and highlights. Thus with less bright light. (e.g. clouded days, close to sunrise/sunset) Or use artificial light on the darker areas to balance the total range.

I hope this makes sense and helps you on the right path.

Hi, Srikumar

This is partly a limitation of compact camera sensors, but in your camera it is made worse by Canon's jpeg processing engine which tends to boost contrast too much. It is possible to hack the camera firmware to allow shooting in RAW + jpeg (a copy in each format for each picture taken), and with a little patience (and some software capable of handling the RAW files) your results will be much better, with noticeably improved dynamic range and better transitions from shadows to highlights.

First make sure that your camera's firmware from Canon is up to date, then just follow the tutorial here: -

It also includes other useful tools such as time lapse photography. It makes you realise that camera companies deliberately disable features that could be implemented at no cost in order to keep the features related to the price.

Good luck!

Hello Nigel,
Thank you very much for your advice.I must do that.I have seen except 2/3 hours after Sunrise and 2/3 hours before sunset picture quality is the best.But in harsh Sunlight at 12 O'clock,it's very difficult to control my camera.Wish in future I will learn more.
Thanks again for your valuable advice.
Regards and have a nice time,
Srikumar
