Sunrise on my D80

Recommended Posts

Taken this morning without a tripod when I happened to look out the window and see the clouds.

One RAW exposed to -2,-1,0,+1,+2 and processed with photomatrix.

CC welcome.

My own comment is that I overexposed a portion of the sky.

Carl, I don't know photomatrix. Do you mean it combined the properly exposed portions off all the images into one image?

It's a nice composition, and there's virtually no way you could avoid overexposing tiny bits of highlight here and there. It does no harm to the image, which depends more on the brooding mid and dark tones for its impact.

My guess is that, even though you just bought your Nikon digital gear, you've had a fair bit of photographic experience before that. Yes?

I'm having fun with the new Nikon.

Photomatrix is a program for tonal mapping to generate an image that has a higher apparant dynamic range than what is possible typically to generate with one photo.

the below is a post I just made minutes ago in a flickr discussion about HDR techniques.

"I have done each of the several variations

-multiple jpegs from auto bracketing

-multiple jpegs from manual changing the shutter speed

-one raw processed internally in photomatrix to an hdr

-one raw to generate multiple jpegs and then hdred

-one raw to generate multiple 16 bit tiffs and hdred

-multiple raws in photomatrix

-multiple raws >jpeg/tiff

Have to say that I love the method of one raw to multiple 16bit tiffs for simplicity and ability to capture movement

You can get dramatic tonal range using multiple raws however.

this morning I took one raw, extracted 5 TIFFs (-2,-1,0,+1, +2) and hdred them in photomatrix.

the 16 bit tiff before hand and then exported as 16 bit tiff allows for more depth and detail control in photoshop editing. "

This is allows you to generate a final image that maintains the details in the highlights as well as the details in the shadows to a greater degree than a single jpg exposure.

My experience with photography begain in 2001 with my first digital camera. I began shooting in manual mode in 2004, and this is my first dSLR. I know many times some of the technical details, but I have much I want to learn and improve in composition etc.

thanks for the comments, carl.

Carl, its a nice image but it does look as if you tried to darken the highlights to try and recover them correct? I can see a number of dark areas where it appears you painted in to try to recover the highlights. Blown highlights are....well blown highlights, there is no way to recover them. As Steve said thats not all that bad in situations like this.

yes, some of the highlights were lost. In the middle (vertically) and on the left hand side you can see one example of an oval area that is white/gray. That is an example of one of the blown highlights. The sky has dark sections in the clouds that are real details from the several different exposures that were blended. I unfortunately ignored the histogram until i had loaded up the images on the computer and then moment was passed.

Here is a pretty good link to explain what Carl is trying to do.

[note from admin: please see forum rules before posting again. Thank you.]

So how do you like photmatrix? Is it relatively easy to use?

i prefer using photomatrix rather than the photoshop cs2 hdr routines. you get more flexibility with photomatrix. if you browse flickr and search for hdr and read the discussions, you can find guides and links to guides on how to do it. It is very easy to use. the most important thing is making sure you have good source material. After that, just fiddling around with the controls is simple.

    • And the bacon gets cooked before the aspargus is overcooked?    Just wondering...

    • My goal this year was to build my own arrows. We will see if they work on September 1st. 
    • You may want to wait a bit longer for it to cool down more.  Dry and hot with fertilizer on it may just burn it up the rest of the way.  This is been one bad year for lawns let alone new sod. 🙁
    • hey guys. Wife and I moved into our new home the other month, and our lawn was looking great. We went out of town for a few days in July and came back to our grass almost all completely brown. I've been water it every evening for roughly 3-4hrs/night. The grass is slowly starting to come back, but not to what it was. And I don't believe it ever will. Our entire yard in SAND and little dirt, we were not able to put down black dirt before due to timing. My question is this: When can I put down weed n feed? or what kind of fertilizer do i need/able to use? or do I not treat my lawn with any chemical this season? 
    • Gotta love the blue-cheese butter!👍

    • Hello from the NW Angle!   On the Minnesota side, spinners and crawler harnesses are still the preferred method of walleye fishing, with the hot colors being pink/gold, orange/gold and orange/chartreuse. Walleye are being caught off of structure scattered in the mud between 20 and 30 feet. Down riggers and deep running crank baits have also been productive.   Canadian walleye are being caught in channels off of islands and along reefs in 18 to 25 feet of water. Both bottom bouncers with a crawler harness and a jig with minnow or shiner have both been successful in Canadian waters.   Musky fishing success has increased in the past week. Fish are being caught on crank baits and blade baits. With water temps in the low 70’s muskies are favoring rocks near weeds.    Our very own, Travis Palmquist, released a 54.5" musky yesterday!   Fall is a great time for trophy fishing!   We hope to see you soon,   Sunset Lodge
