 |
|
Attached is an image I found online with the before and after versions. Has the "ironing" been done through photoshop or do you thing that a new ironed suit has been pasted over the wrinkled one? That leads me to another question: how do you find a picture of exactly the same suite worn in the same position as it is in the original image?

This is simple. Select wrinkled area and apply Filter->Blur->Smart Blur or Surface Blur.

I would steer clear of the blur method altogether as it does not produce the result you want, and I challenge anyone to get close by doing so.
Really the only way I know that is effective is splitting the frequency of the image, into low and high pass. You do this by using the apply image command, I give a brief explanation in this thread Split Frequency The settings are different for 16bit images and if you need the settings or more details shout back.
To remove creases, work only on the low frequency layer and unify the tones. I can provide more info and a demo if needed.

Yes please provide me with more info and if possible a demo about the low / high frequency.
First of all, what is this frequency of?

Kind of strange to read it given the fact that Smart Blur and Surface Blur do just this - "frequency splitting" behind the scene  Ever wonder what is Radius parameter in these filters for? Right! - the threshold for frequency splitting
I used Surface Blur for given picture and got exactly the same result as on the right picture.
Of course, you can always do everythig manually but it never hurts to know some things about PS tools and how they work

Will post a reply to both of the above answers when I'm more able to respond without fear of alcohol clouding my answer  (Cheltenham horse racing did for me today!)

I want to know more about Cheltenham horse races.... sorry Netaddict that's rude of me... Um, if I were a betting person I would put money on Photoshop rather than on New Suit...

I was going to write a long winded reply, but in actual fact find it slight pointless as others have trod this well worn path before. So I will simply add a couple of links for people to read at their leisure. No point going over stuff that folk better than I have prepared
Split Frequency
Using the above technique for splitting the image into various frequencies, by working on the low pass (blurred layer), it is easier to get rid of the creases in fabrics, whilst maintaining texture.
Not to bore with my diatribe I point you to Sean Bakers blog, I think it's all fascinating, but read on from Dirty Secrets/Dirty Tricks and down SB's Blog
There is loads of information out there on the technique and the ins and outs or limitations , I don't intend to add to them
And @SCTRWD, I almost laughed at your response because you state a pretty simple fact, that and under all the bells and whistles splitting frequency is also 'blurring'. It does contain some distinct advantages though, bandpass sharpening is possible and a few others. I didn't mean to dismiss your method so offhandedly, as we all know results are in the end what it important.
renata, all you need know about horseracing is that I have no nack for picking anything other than donkeys and nags. Not one win yesterday

@thehermit, just the other way around: I stated the simple fact that Surface Blur uses "splitting frequency". Just like some other filters do - Unsharp mask, for example.
Splitting frequency tecnique has been around for quite some time and been incorporated in many tools and filters. They just do it more friendly and screen the gory details from the user.
I've been using raw frequency tecnique for some years by now for some complex cases where it took several frequency bands to isolate the problem areas.
But I don't think this is the case here.
Having said that I think we should stop throwing dirt at each other... Unless you think different, of course
P.S. Glad you had some laughs, anyway. They say it makes your life longer
