Thanks to all for their considered replies. Just spent the weekend at Bathurst and had a picnic at Sofala where there was huge numbers of these wrens, mainly females but only had my Samsung phone - so sad. Couple of questions further.
1. I have RawTherapee <cite style="color: rgb(0, 109, 33); font-family: Arial, Helvetica, sans-serif; font-style: normal; -ms-word-wrap: break-word; background-color: transparent; font-variant-numeric: normal; font-variant-east-asian: normal;">rawtherapee.com </cite>and Canon's own editor Digital Photo Professional 4 which I have used with raw files with limited time practicing. Main reason for these choices are that they are free and I wanted to experiment before committing to paying for a software program. Is Lightroom or Photoshop better for my purpose at this early stage?
2. What function/s brings out detail in shadows?
3. Tried the sharp/unsharp mask on a massively zoomed in sample but couldnt pickup any benefit. What am I looking for?
