Re: The perfect settings? For me, at least...
Very nice images Disjecta. Just for curiosities sake I took all three of the images into photoshop and performed a "digital haze burn" on them (mentioned this in another thread). I wasn't expecting it to do much but it certainly did! Give it try and let me know what you think:
Unsharp mask:
Amount: 16
Radius: 40
Threshold: 0

No, no, I was just focussing the post away from me and to the detail issue....
I certainly appreciate your feedback.

Nothing all that special really. It's basically just a simple sharpening to enhance contrast. Photoshop compares the all the pixels against pixels in a specific radius. The photoshop manual says:
"Unsharp Mask locates pixels that differ from surrounding pixels by the threshold you specify and increases the pixels' contrast by the amount you specify. In addition, you specify the radius of the region to which each pixel is compared."
Interestingly this can cause saturation of the various colors. You can apply sharpening without affecting the colors though by converting the image from RGB to LAB and sharpening the luminance channel.

Shaw,
This is an awesome tip, the effect is so subtle but it really makes the image come alive. Because Premiere integrates so closely with Photoshop, I have the exact same effect in Premiere and have saved it as a favorite.
Thanks again...
Thanks again, Jigmic....I'll keep the wildlife coming

Re: The perfect settings? For me, at least...
Shaw, can you be more specific about this Photoshop tip please ?
What are you using exactly and where in PS should i found it ? (I'm fairly used to the soft but i have a CS french version and i'm having a hard time trying to find a correct translation for Unsharp Mask...)
Thanx
Nico

Re: The perfect settings? For me, at least...
No problem Encheval,
I hope this translates well. If not let me know and I'll keep trying
Take a look at the top menu bar
Head over to the "filters" drop down box (6th over from the left)
Drop down to "sharpen" (the 8th down I believe)
Select "Unsharp Mask" (the fourth and last sharpening option)
Apply the values listed above

Re: The perfect settings? For me, at least...
One thing to note which I forgot to mention:
You probably will have a hard time seeing any change. The best way to see this is to use the key commands to flip between the changed and the normal version. It becomes apparent easier this way.

[quote author=disjecta link=board=Events;num=1098303335;start=0#0 date=10/20/04 at 13:15:35]I have found that video noise is very prevalent in this camera using the presets for f5 or f6 and, as noted by others on this board, I can attribute it to the Cine matrix. I changed that to NORM and made sure gamma was set to Cine-Like (not D or V) and the noise level during low light shooting is drastically reduced. V Detail and Detail Coring are left at 0.[/quote]
disjecta,
how does setting up gamma to "high" and matrix to "cinelike" compare to your setting above as far as noise goes? thanks!

The unsharp filter is a digital photographers secret weapon. There's some good articles out there describing it. Here's one that's a good quick explanation:
http://www.microsoft.com/windowsxp/using/digitalphotography/learnmore/sharpening.mspx
Note the "When to Sharpen" section.
And a couple of others:
http://www.bythom.com/sharpening.htm
http://homepages.inf.ed.ac.uk/rbf/HIPR2/unsharp.htm
It's also funny that the name is "unsharp" since it does the opposite. That's because of the method in which it sharpens which is explained in the links above.

I'm not sure boo....I'm happy with the NORM settings right now. If you get a chance to experiment with it, please post your results here.

Hans, thanks for the great links!

Re: The perfect settings? For me, at least...
i just tried out those settings (ive had my camera for a day! woo!) and I love the settings, colours are much more vibrant, i like the darker look to it. now i just need to figure out what all that stuff means, hehe.
did you use any extra lenses on those shots? or is that straight from the camera?

Disjecta,
i made tons of testing with the DVX100A and i agree 100% with you.
First, this camera, when used with cinelike colormatrix and cinelikeD gamma, is a real big noise generator, unusable for any professionnal work, really Unacceptable.
But once well adjusted, this camera can also produce realatively clean and very gorgeous images.
Do you want to laugh ?
make this little test with your DVX100A:
1-set the gain at 12db
2-use thin v detail setting
3-use the cineklike (original) gamma setting
4-shoot at a dark scene.
5-play with the detail setting from -7 to +7
amazingly, the noise decreases when you increase the sharpness !
he he...i mean, it's funny...
If you do the same test with the "mid" v detail setting, it will not react the same, the noise will then increase if you increase the detail adj.
