Yabor, that looks unreal. Great shot, but for my taste a little bit over-sharpened. Less is more here.

Holy Craptacular that is incredible.

Are you telling me that thing went off yesterday? I didn't see a thing in the news about it.

Well this eruption certainly explains all the rain we have been having. Yabors great Dutch Skies too.

What a pleasant picture, Rico. I'm fond of rain.

smithz, yes I know, I ruin many a picture by over-sharpening it. Everybody tells me to leave that sharpening-slider alone. But I can't seem to help myself. --In the picture in question I think the out-of-focus clouds contrast rather nicely with the razor sharp foreground.

Let me take this down cause I'm showing you
Mulberry Leaves
F-stop 19
Them greeny things that hung about
Mulberry Leaves forever

Shooting is easy with digital
Computerizing all you see
It's all blurred in raw for some, but it all sharpens up
It doesn't matter just say cheese

Music by Melon John
Lyrics by Bernie Cantaloupe

Coolpix pickin up Dutch schtick
Don't you know I'm feelin' melon
I love your Petra cute, the way you slice your fruit
Baby, make me feel so melon

It's the same green pealing, that is torture
When you're steeling back into my orchard
With the shutter closed, oh and the ISO low
My there is so much less grain

water melon. This is a HDR picture (the melon picture above was straight from the camera). Good result: shadows lightened without burning out the highlights.

Cool piece of silly, broeder Brad. Hell, I miss Silly a bit.

Here is the first photo HDR-ed. Much better, I think.

By the way, this ain't hardcore HDR. It's just a blend of the orignal picture with a lighter copy and a darker copy.

HDR
by Paul Lemon

When I think back
On all the fruit I shot in grayscale
It's a wonder
I can shoot a damn
And though my lack of chromacation
Hasn't hurt me none
I can see that setting in the cam

HDR
They give us those psycho colors
They give us the greens in numbers
Makes you think all the world's a druggy haze, Oh yeah
I got a Nikon camera
I love to take a chromagraph
So Obama don't take my HDR away

Nice wordsmithing there BN.

I haven't made much of an attempt at HDR. I am accustomed to using Photoshop in particular the ACR RAW plug in engine they developed. I opened the original Melon image with ACR to make adjustments to the image below. One major thing I did was change the color profile to the file. The file on my end has a generic Camera RGB profile. After adjusting it in ACR I opened it with AdodeRGB profile assigned. The file is red saturated. AdobeRGB tends to exaggerate the red channel. I switched the color profile to sRGB IEC 1966-2.1. It has a smaller gamut than AdobeRGB mostly in the red channel. I think sRGB IEC 1966-2.1 was one of the original digital color profiles. More so for on screen viewing. AdobeRGB is better for printing as it has a larger color gamut. There are other profiles with even larger gamuts.

What I attempted to do was bring out the dynamic range of the image by striping away that red channel layer. I made other adjustments as well. ACR has a lot of control over the image. Not as much over JPG as a native RAW file from the camera.




Broeder yabor was the original file a JPG straight from the camera?

Thanks for taking the trouble, broeder Rico. I think the original file was straight from the camera, but I'm not completely sure because quite often I make the photos a bit lighter before posting; often I also hit that magic wand button in iPhoto. (I have the camera set 3/4 stop too dark to avoid blown-out highlights). Anyway, to make sure, here is the original jpeg file , not tampered with in any way.

I really should take your advice and shoot RAM as well.

The skin tones in your version are fantastic; so is the wood. The melon looks very natural too, though in reality it was really a bright darkish red (with some purple in it, I suppose).

Do you suggest I take the saturation down a bit on my JPEG settings?

I liked that photo hotter, it made it about the reflected light of the melon off of sister Petra's face. Rico's has some beautiful tones, they're more naturalistic, but it kind of removes the edge of humor. I love your portrait work, your style is becoming very developed.

I put Yabor's photo through my HSR filter (High Surreal Range), and this is what I got.

Very nice, Brad! That vortex is very original and the purple of the bowling ball looks great.

Lady You're a Rich Red
by the Redtles

How does it feel to bleed
One of the vermilion zusters?
Now that you know blue you aren't
What do you want to beet?
And were you marooned very far?
Far as the blush can see.

How does it feel to bleed
One of the vermilion zusters?
Have often have you been rouge?
Often enough to glow
What did you see, when you were flare?
Nothing that doesn't tone

Lady you're a rich red
Lady you're a rich red
Lady you're a rich red too

This is fun at zuster Petra's expense.

I felt the same way thalo did that the over all red was definitely influenced by the melon. Makes sense. That is some really strong light reflecting off the melon which is being absorbed by Petra's face.

What happens this natural effect is being enhanced by the parameters set forth in digital capture. Which is in turn influenced by the color profile work flow. Changing the color profile drastically changes the color point of the image. Most often it is the red channel being affected. Yabor's original image was shot using the sRGB IEC 1966-2.1 color profile. When you change the color profile to AdobeRGB which has a larger over all color gamut, color is being added that was not originally recorded at point of capture. An exaggeration takes place that pushes the red channel beyond the original intent when assigning AdobeRGB in this circumstance.

I really stripped the red from the image to get to the flesh tones. I cheated the image by using the color controls in ACR. You have control over three aspects of the color characteristics of the image. Hue, Saturation, and luminance. I find the the luminance channel is were the most influence is taking place affecting the over all sharpness of the image. When I adjusted the image above I only adjusted the luminance aspect of the color.

Working with the original image I think shows what can be done digitally that can not be done working with B&W print film exclusively.

The image below completely defuses the situation by removing all the color. This was done using ACR. The color control panel allows conversion to grayscale were you can adjust each color channel to fine tune the tone and contrast which influences sharpness in it's own right. Digital allows for both color and B&W capture simultaneously.


For something completely different:



yabor there are a lot of things that influence the image in regards to camera settings. First is white balance. I tend to change the white balance according to situation. I rarely use auto-white balance. You can even do custom white balance using a white surface to record the ambient light to set white balance. Not always convenient but delivers excellent results.

Second the camera has settings as you know that affect the JPG output. You can try adjusting them to suit your taste. Saturation. Sharpness etc... The scene modes basically are adjustments to those same parameters.
