"Save as" options - Tiff, PSD

[proseak]

Is there a way to make sure that when saving a 16-bit image using "Save as", it defaults to Tiff, rather than PSD?

It's on Win7/CS5, btw

TIA

Good question.I did a search and this is all I could find.

Selecting the required format from the appropriate 'down arrow' box will give you the required options and I find that it tends to default to the last used format. But I'm not sure if you can restrict those options.

For me, the greatest concern is getting confused between Save and Save As.

Out of interest, why would you want TIFF over PSD? PSD is smaller.

Because you can open TIFF in ACR, which provides a quick'n'dirty way to set a black point, shadows, and highlight control. The NR is pretty good, too.

Hi Peter,

Yesssss ... buttttt ...

It's not hard to do those things in Photoshop either - and - there's no technical advantage to doing it in ACR once it's no longer a RAW file. Plus, smart object gives another option if you make global tone adjustments once of your first priorities in Photoshop "proper".

Personally I normally hand off the file from ACR to Photoshop with a touch of "wiggle room" in the histogram, and then usually all I need to do is adjust the clipping points and mid-tone slider in a levels layer; the initial adjusting of the DNG file is always done in ACR though (and I can spend quite a bit of time doing it if need be).

Why are you needing NR anyway?

[proseak]

I do quite a lot of HDR, which leaves poor black poiny, uncertain shadows, and low local contrast. These are all (very)easily fixed in ACR. The NR is a useful option - nice to know that it's there, and very handy indeed for scanning work. Oh, and you can save as DNG.

Actually Colin, I got the idea from you - "if it can be done in ACR, it should be" but I've played with it a bit. It really is a versatile and fast way to accomplish a lot of tasks at once.

True, but by far the big advantage is the ability to tailor the conversion whilst the image is still in linear gamma ... unfortunately, these advantages disappear once the gamma is converted (although one might also argue that there's still a LOT of headroom in a 16 bit TIFF / PSD - and - if any large adjustments need to be made then they should already have been done at the RAW / ACR stage).

I agree that it's very versative for (mainly) global adjustments though; perhaps Adobe should give us an ACR type control in Photoshop (call it an "experts panel or something) (although I guess that Smart Objects are kinda like that, to a point).

[proseak]

The thing that i like about ACR is that it does so many things in one go, and does them so well; often the only thing that i need to do in PS is sharpen(and concerning NR, you can sharpen a noise-free image much more aggressively).

Yes, a "global adjustment" panel would be nice in PS

So, is there a way to persuade PS to save as TIFF, rather than PSD? (They're also visible in Explorer, which can be useful)

Yes - just select if from the drop down box when saving ... you lazy little toad!

Failing that, would an action accomplish that - perhaps assigned to a button in "button mode", so just literally 1 click away?

[proseak]

"you lazy little toad!" - my secret's out, I see...

About using an action, I'm not sure if i can make it save to the same folder. I do use something similar for JPG out put - flatten>8-bit> Save as 11-point Jpeg, to a default folder...It's the destination I'm not sure about.

I'll have a go later. Thanks for the suggestion.

Are PSD smaller than TIFF? It's been a while since i compared, but I found the filesizes similar. More experimentation!

I haven't compared for a while, but off memory, by about 30% on average.

I just did a quick test on an image, and found out that:
-TIFF using LZW = 61.1 MB
-TIFF using NONE = 57.4 MB
-PSD = 51.0 MB
-TIFF using ZIP = 48.0 MB

The image is 3872 x 2592 and 16 bit.

Obviously the LZW TIFF should not be larger than the uncompressed TIFF so this must be an anomaly. However, it should not matter because the ZIP is smaller than all three. For the last couple weeks I have been saving files in both PSD and TIFF ZIP and the ZIP is consistently smaller.

[proseak]

I've just run a test on a few 16-bit images, and the results were as i expected - here's a screen capture;



I understand that LZW is counterproductive for 16-bit images, but uncompressed TIFF & PSD are within 1% of each other.

I'll try again with the image;

Just did a quick test myself with a 16 bit file ...

I think that your images must be more "complex" than mine, Colin - mine are flat 16-bit from a 550D. I uspect that my workflow is rather old fashioned - I still find myself using techniques from PS6, and not using the more advanced methods in CS.

I've tried creating an action to save as Tiff, and can't make it save to the current folder, but only to a default. That'll have to do!

That one has an image layer and I think about 3 adjustment layers.
