Taken from a electronics forum

"Excessive UV may bleach the least stable of the color filters on the
Bayer mask which in the regions where the bright spots are focused and
could alter the color balance permanently. "

Apparently it doesn't really hurt the CCD or CMOS, but the organic dyes used on the lenses themselves or as a coating on the sensor is what is damaged.

I don't know, I guess it looks fine. There may have just been too much light in the marsh picture.

Here's a raw picture I just took, I don't see discoloration or spots...

Steevo · Jul 19, 2010

I found it easiest to put the camera in timer mode and into a box for a perfectly black shot (no flash obviously) and then with a manual focus and apature and a white light shot. Check them and then invert the colors to see if anthing appears.

A quick macro shot taken using the Fujifilm S1800 @ ISO-64 and a resolution of 9mp in 16:9.

If I used 4:3 I'd be getting the full 12mp, but, I think it looks OK as it is.

More to come. :toast:

DanishDevil · Aug 2, 2010

I had a Casio Exilim Slim a while back, and it took shots at a really weird aspect ratio (fairly close to 16:9) but I loved all the shots like that. I think we're all getting so used to stuff being in 16:9 that we prefer that.

Been playing around with HDR (High Dynamic Range ) processing. Going to take some time to get the hang of it, but very interesting.

burtram · Aug 5, 2010

Thought I'd share my DIY Flash diffuser, lol, I'm not sure where, but it was probably somewhere in this thread was the link for all the DIY camera accessories.

It actually works really well, I was very surprised. And I just did a quick trace of a lens hood for my camera on card stock and cut it out with an X-acto knife, took all of 2 minutess to make.

Took these in low light with that diffuser:

I love it, no harsh bright flash on the subject being photographed.

Cool. Glad my link could help. :rockout:

Found it here on this site: http://www.diyphotography.net/
Amasing ideas there.

What I found with HDR is that I can't look at it too long to judge unless it's early morning and my eyes are fresh. Otherwise it fatigues my vision and things get dim around it. This is with my contrast ratio at only 25. The other thing I've found is it's kinda awful. Trying to take the perfect picture while staying within the palette of reality seems much more fulfilling to me. I want perfection as my eyes can see it.

Really depends on what you are trying to achieve with HDR. Yes, there are alot of "hyper real" HDR photos out there, and some like them. My focus is to eventually get to the place where the end result is real enough to leave you wondering.

At the end of the day, the camera's dynamic range is about 40% of the eyes. My focus is to try and improve that without going too cartoonish.

I like them

Red calipers are next

Wile E · Aug 8, 2010

Very understated and elegant. I like them. Don't go red tho. Too many people go "ricer red" on their calipers. Do something different.

burtram · Aug 8, 2010

Went to the air show today, got some cool photos:

This one is just awesome, it looks like an illustration when I tweaked it just a little bit.

The one in the middle, is speeding through the center of the others

Then i made two versions of this one, because it came out really kinda cool when really tweaked:

V2

Rakesh95 · Aug 10, 2010

Dont have a macro lense, gave a close shot a go anyway!

Rakesh95 · Aug 10, 2010

Taking more random pictures

I really like the clarity of these snaps as well

If I were to give anyone a tip, it would be to use a really low DPI, I think I used 100 for this..

Finally!

Well finally went for it! yesterday i got myself a Canon EOS Rebel T2i Black 18.0 MP DSLR w/ EF-S 18-135mm f/3.5-5.6 IS Lens From my local ChristianPhoto ! It cost $1099 but came with

Errr...

That's because a lens hood is for avoiding glare from extremely bright light sources like studio light / sunlight across the lens.

The odds of you NEEDING a flash when exposed to extremely powerful light sources ain't very great, and even then - the other light sources would probably make sure & sort that shadow for ya

Damn, that is a nice camera. It can actually do up to 6400 ISO native. That's impressive. Wonder what just the body only would cost?

EDIT: Body only is $800 on Newegg. Canon EOS Rebel T2i Black 18.0 MP 3.0" 1.04M LCD D...

I might pick this up at tax time to replace my EOS Rebel XTi. I really want one with live view and video shooting. Might as well upgrade to a better sensor and have better ISO capabilities in the process.

burtram · Aug 14, 2010

What's your guys' opinion on buying a lens used or refurbished, online? I can get the Sony 55-200mm lens if I buy used for $104, $140 for a Sony 75-300mm as a refurb or I could get the Tamron 75-300mm for $90 used. Now, being unemployed, I don't have much to spend.

My current thought of purchase is, buy the Tamron 75-300mm lens and some filters on amazon for a total around $120, but I am open to input, as I have no experience with Tamron products, nor do I have any experience buying used photography accessories online.

I have a Sony Alpha 300 with the 18-70mm lens and I really want a new zoom lens to play with.

Taken with my iPhone 4, not bad I think

You do know that anytime you post a raw iPhone picture, people can get the coordinates of where it was taken through an EXIF viewer right? Always gotta keep that in mind, esp. when the photo subject may be incriminating.
