Help

Last night I added a couple of pics of my sister fast growing puppy in this thread.

Puppy PIcs

When I came into work this morning I checked my plummeting "shutter speed" score and looked to see if anyone had responded to the puppy pics.

On this flat screen monitor the pics below are waaaaay oversharpened and a bit dull in colour. At home they were slightly too sharp but ok.



photography issus aside, could you please tell me how the sharpening looks on your monitor.

I'm viewing on a powerbook screen, and they look just a little oversharpened, but nothing I'd probably notice if you hadn't said anything.

Colors seem okay to me.

Mac iBook laptop ... sharpening fine, coat color a little muddy & lifeless (on the two shots posted as thumbnails in this thread, compared with the linked Puppy Pics) ... very nice dog.

For what's it's worth - my impression is that the two posted on this page had a curves adjustment done to them to reduce the nearly blown out highlights, and that it has taken the life out of the image. Maybe a slight warming of the color balance and then a boost of saturation would improve them. The other two, from the puppy pics page, look oversharpened with blown highlights. They are more defined and have the color but definitely look way oversharpened. Since it's your sister's pup, I'd suggest a re-shoot. Assuming your 350D can do some of the things my 20D can, try using partial metering and see if shots with -1/3 or -2/3 exposure compensation look better.

Just my two cents, hope it's helpful.

I'm viewing on a CRT and there is something wrong with the photos. Its not so much the dog that concerned me, its the background. There are several areas in both pics that show strong pixelization. Hopefully that will help with the Dx.
As for the dog, fact that he's grown makes a lot of difference, his coat is rougher and longer now and will photograph differently.

On a CRT too (Sony 20") and the background is winky. There is banding at each bottom corner, particularly on first one. Lots of sharpening artifacts in the trees of both. Dog looks like its been sharpened but its a personal call if its oversharpened or not.
Hope that helps!

Something looks a bit funny in the background for me also, but I thought it was a screen window or something behind the dog that wasn't quite blurred out - not pixelation. Has a diagonal square mesh look to it.

Looks a bit oversharpened otherwise, but not much really.

FWIW - 19" Dell Sharp FP LCD

Neither are over-sharpened, the first has something weird going on, either noise or something else, the second one isn't as bad...I think bumping the contrast a small amount might help them both.

They look sharpened with Focus Magic - if you used USM, then I'd say they are a touch oversharpened, but nothing I would really notice unless I got an 8x10 of it.

I agree with a levels/curves being needed though.

the first one on this page has blueish/white under the left ear (your left) and the second has it by the other and on the back of the neck. Did you do a selection them sharpened the forground or blurred the background? Might need to clean up those areas. Otherwise coolbar had the right idea about boosting it some.

btw older 19" DELL CRT here.

i love both but who am i to judge-i just moved up to progressive lenses not for my camera but for my eyeballs-but for realthough-both pic's are excellent i don't see any problem with the background.
11/04/2005 12:54:23 PM · #12
yes, there is something weird going on besides sharpening. looks like you did some sloppy cloning of something in the background maybe? besides that the images look like mine do when i take a 100% crop of the image, and for that reason i never do it. it's not sharpening persay but it has a similar feeling.

It does look to me like the sharpening has been taken a little too far, I'm seeing this both on my CRT at home and on my LCD dislpays at work. I think the fence was made more prominent by the sharpening, which appears to have been done with a rather large radius. I see som signs of a halo. The original obviously had good fine detail, so I'd re-sharpen using a small radius leke 0.3, and make sure your threshold value is NOT set to zero, to avoid bringing up the noise, which is visible in the darker areas.
Once you've got the sharpening squared away, try to apply some vignetting to darken the BG and lessen the prominence of the fence, and/or apply a very gentle blur to the fence to fade it a bit.

Thanks folks for your time and comments

Yes there is some sloppy cloning out of "garden stuff" in the background

The shots were just for fun so no harm done, I was just amazed at the difference between the monitors. Your comments have all been helpful.

Cheers

re-post production

slight saturation boost and teeny weeny bit of sharpening

The dodgy background cloning aside, is this better?

Steve, yep they look much better. I had a go at the colours hope you dont mind

I think what might help a lot is a Levels adjustment. Make a Levels adjustment layer, go to the blue channel, and tweak the grey value (middle slider). Pushing it to the right a little bit. That should unmuddy the colors a bit. Then go to the RGB channel and push the leftmost (black) slider up to about the beginning of the hump on the histogram, and also push the right (white) slider a bit to the left. Some adjustments to the red channel will also probably help, pushing the grey to the left and the black to the right, which will bring out the red in the dog and take out the red from the background. I hope you don't mind, I made similar changes myself for the sake of example:

The dogs don't seem especially oversharpened on my monitor either (but close call), but the background is wiggy (again, the mesh thing going on). I'm on a Compaq Presario R3000 laptop (1280x800 pixels, 32 bit color).
11/04/2005 06:47:08 PM · #19
I have no idea lol. I left you a message under comments. But in case you don't see it. That is one pretty pooch you have. Is she a red setter gordon setter mix? We had neighbors with a gordon setter and she was so pretty- and very smart I might add!

NEC Multisync FE 2111SB CRT, i see them a tidge oversharpened, but mostly on the hairs that stick off the head and ears.

If you have Photoshop there is a sharpening trick with USM that you might try to get a sharper, but not overfocused look with higher USM values... Here are the steps:

1-Make copy of flattened, final image... apply original USM sharpening to it.
2-Duplicate sharpened layer.
3-Set mode of the first USM layer to 'darken' and set the mode of the duplicated USM layer to 'lighten'.

USM is achieved by adding white pixels to one side of a border and adding black pixels to the other to increase contrast and make things 'sharper'. Step three separates the white and dark USM pixels into separate layers that can be adjusted independantly with layer opacity adjustments.

4-Try adjusting the opacity setting of the 'darken' and 'lighten' layers separately to fine adjust the focus to your taste.

My experience is that I usually leave the 'darken' layer at 100% opacity but set the 'lighten' layer somewhere below 40% opacity.

Try that trick, you'll like it. Just be advised it cannot be applied to DPC images entered into basic challenges because the 'normal' mode setting is the only one allowed for layers. It is OK for member challenges.
