Ok, I've got a bit of an issue with some pictures here which were shot at ISO 1250 and are a little out of focus... Some is actually closer to 450...
I need to get these things processed and ready in 4 days...
I'm pretty sure that I'm not going to be able to do much with sharpening these, between the noise and soft focus, so I need suggestions...
One thing I was considering is the possibility of downsizing the images, then applying a bit of sharpening... I often find that this irons out a fair bit of noise, and can give a bit more headroom on the sharpening before going into oversharpening...
The pics are unlikely to be printed any larger than 5x7, but some probably WILL be printed at that size.
I was thinking about possibly downsizing them to 1024x768 type size, then letting the print shop do the interpolating and upsizing... While this sounds like it's a bit underhanded, it's really going to be quite acceptable for the customer (and the pay for the job :).
I can pretty much guarantee that the prints will be done at a standard print shop, not a high end deal at all, so I'm thinking that the shots will be indistinguishable in print.
Has anyone ever tried this?
Any other suggestions?
I might add that I'm doing this in my off-hours... I am working quite a bit this week too... |

| Can you post a sample or two, let us see what you've got to work with?? |

1200x1600 will give you decent results up to about 8x10, so you might want to go no lower than that in your resizes.
However, I don't think you are going to get rid of the noise by down-sizing. Yes, it supresses some of the noise, but it also supresses about the same amount of detail. So, you're not gaining any Signal to noise ratio on the down-size and your probably better off at the larger size.
As far as soft-focus goes, if you are running PS CS2, smart-sharpen can do quite a bit. It can't do miracles, but it can get slightly soft images to appear more sharp.

| Second the suggestion of using Smart Sharpen, or a program called Focus Magic. Both use deconvolution techniques and are superior to simpler sharpening techniques for slightly OOF shots. They should be run on the full-resolution shots, not on downsampled versions. |

My friend recently took a course and has an extra copy of CS2... He's going to let me use it for a bit... I was supposed to get my hands on it last friday, then last saturday, then sunday, and at around 8:00 this evening... Currently I'm waiting until tomorrow evening 'sometime'...
I'm sorry that I have no examples yet at this time... I just finished sorting the images and I've got around 80 more to 'redo' with the white balance (learned some tricks towards the end that I didn't do very well in the first couple hundred pics... most had to be hand-adjusted for white balance... see my rant about stage lighting and opposite colors...)... but I've got work tomorrow morning and it's nearly midnight... I haven't had dinner yet... busy busy! |

As always, kirbic is right about applying sharpening to OOF originals on the FULL sized image. Doing it at full size is the key. Just don't overdo it. (In normal images you apply most sharpening after resizing)
In addition to 'bicubic', CS2 also has two new resizing options that affect sharpening. It is recommended when downsizing that you try 'bicubic sharper'. It has a sharpening effect on the downsized image. If you try it and it oversharpens the downsized image then go back and use the standard 'bicubic' selection. That is another option to think about.
The images will be downsized for printing anyway which will further reduce the OOF effect from the originals, so you will probably be just fine in the sharpening department.
Btw, you may only be allowed to install your friend's extra copy of CS2 as a fully functional 30 day trial if it been installed before. That is how Adobe protects their single copy licensing these days.

Interesting stuff, thanks...
30 days will be enough... I hope :) |
