In photoshop if you want to approximate the effect of increasing exposure by
1 or more stops, do you adjust the contrast alone, or gamma as well? If you
have to adjust gamma, then what is the formula?

Yes, I'm going back to some older images.
Scanning color negative film, mostly Vericolor VPS from 80's with Nikon
Super Coolscan V. Software is Nikon Scan 4 and VueScan (current ver).
Nikon Scan seems to do a fine job of scanning slides. The images are

if I process raw of pictures where there are areas with burned lights, and I

I've made a direct comparison of RAW data per unit of area in the deep
shadows of ISO 100 between the FZ50 (1.97 micron) and the 400D (5.7
micron).  Exposure is the same, same Av (f/4.5), same Tv (1/100), same real

Hi folks. My elderly parish priest (again) gave me his camera to have a look
at it this morning. A NikonCoolpix 5700. He told me that it wasn't focusing
but the problem is much more serious I think. I got it sorted out focus wise
but the pictures all have numerous lines across them. ...

I just saw BenQ E1000 in one store. It has 10Mpixels, 3” display,
manual controls and 3 x optical zoom…
Can someone tell me is it a good camera?
Or you can recommend me something else for a similar price?

I recently decided to get a digital picture frame. I ended up with the
pandigital 7" widescreen. The only real problem I have with it, is it
will not shut off via the on/off program while in slideshow mode. It
works fine and will shut off and on if I am viewing the calander or a

Nikon does it again by introducing another new camera designed exclusively

flashes/accessories) I was never able to recoup the loss and so I fell
out of the occasional freelancing habit.

I used to be quite happy with Photoshop Album, but it can't handle the
amount of photos that I have now. A friend told me that Photoshop
Album is based on an access database, which is not suitable for
handling more than 20.000 entries. So no wonder that it got really

Canon (and probably quite a few other camera manufacturers) offer
interchangeable focusing screens.  I have never experimented with different
focusing screens.  Has anyone had any experience of these on modern DSLR's?
The slowest lens I use is 2.8 (although I do sometimes shoot ...
