As you know, using sRaw means you get half the linear resolution. The fact that Canon includes it as an option on high end cameras such as the EOS-1D Mark III is enough for me to know that it has its uses. As a result I am quite happy to stand by my advice that "if you don't expect to produce large prints but want to retain the post-processing flexibility that RAW files offer, sRAW may be an option to consider".
, please forgive another "off-topic" excursion in your thread while I take a moment to respond to G's questions.
I'll pass on any collaborative ventures but "Thank You" for the offer. I am sure forum members will welcome your thoughts but please bear in mind, as you prepare, that there is no "one size fits all" best setting for the 40D, or any camera. Highlight Tone Priority (HTP) has its uses (a bit like sRAW) but if it just made everything better all the time Canon wouldn't even offer the option to turn it on (shipping default is off) - they would enable it all the time. I have tried it and generally prefer to leave it off and so retain the option of setting ISO 100.
When you start your new 40D thread (not here please
) would you take the time to provide sources for your assertion that HTP increases the dynamic range as I seem to have been labouring under the misapprehension that HTP works by modifying the tone curve and that the dynamic range of the sensor remains the same.
And yes, please drop the childish epithets.
