They do - Epson v850 will save in tiff and most (all?) raw is a camera manufacturer modified tiff.

I'm fairly certain all higher end scanners save tiff and if not it's all down to the software. Try the excellent viewscan or Siverfast (if you have more patience and money!)

Anything is possible in the photographic world according to some of the CSI shows.

I have scanned in photos as well as early jpeg files from 2005 (scanned in photos from the 1960's) this is where this application comes in handy.

While clever, seems backward to me, only reason I can think of not to shoot straight RAW is to shoot RAW & JPEG Fine. I can afford a few larger memory cards (they have become so reasonable, makes me smile) so why not shoot RAW or RAW & JPEG all the time. Not picking, yes sounds clever, probably does a decent job, but I can get at least a gig of high quality memory cards for $79, maybe more, even at B&H (which reminds me that I need to go back and pull the trigger on a couple). Thanks for the info. I suppose I will try it at some point as an open minded person.

I did chuckle on the "Witchcraft" comment!!!

Edit JPEGs as if you shot them in RAW.

Topaz JPEG to RAW AI uses machine learning to do what was previously impossible: turn JPEGs into high-quality RAWs for a better editing experience. Ever come across the perfect shot and all you had was your phone? Now you can take the shot, then take your compressed JPEG image and convert it to RAW in Topaz JPEG to RAW AI. It's the next best thing to having your trusty camera gear on hand! With JPEG to RAW AI, you can prevent banding, remove compression artifacts, recover detail, and enhance dynamic range. As the first and only A.I. software for transforming your JPEGs into RAW files, what used to be impossible is now possible.

The level of misunderstanding of JPEG, how it works, and what its capabilities and limitations are on this site continues to astound me. And most of the misconceptions are preached loudest by those who clearly do not even use it and who have obviously never studied it in any detail.

Hooray, we have a winner. I've said before that jpeg is more misunderstood than raw and it's capabilities understated and limitations overstated ad nauseam by those wearing the raw Tshirt.

The truth is that JPEGs can carry all the information that most printers can handle and reproduce, especially any printer that most of us here are willing to pay for and buy ink for. I have very nice framed images all over my house that were taken before I learned the benefits of either raw or TIFF. Most of them were post processed. They are not going to come down just because they were JPEGs.

Yes. The world if stuffed with fantastic images processed and printed in jpg format. I think a lot of folks don't know how to process a jpg. For example, many times I've read that you can't fix white balance except in a raw format. That's not close to true. Over and over it's said if you plan to edit your images you need to shoot in raw... That's also not close to true. Also it's always said jpgs have way less data, throws away tons of data... not often true. Jpg compression mostly encode colors that are too similar for the eye to differentiate as the same color. The amount of dissimilarity is determined by the compression level. Also, if you repeatedly compress the compressed file, jpg will continue to encode similar colors so eventually, the picture can begin to degrade. There is no reason to do this, so it is a non-issue, that is repeatedly preached as a jpg flaw.

But the truth is that with the correct choices, JPEG does not have to be the limitation that so many here make it. With correct camera setup, correct focus, and correct exposure, it is possible to get to a perfectly usable printable image with JPEG. BUT...the correct JPEG setup is also required...maximum resolution retained and minimum compression exucuted. If Basic quality is selected, only a low resolution version of the image is captured from the beginning. If Small is selected, a brutal compression will be done that will result in inability to fully reconstruct the image when opened. But those are choices that do not have to be made.

It may be true raw can give you a bit more latitude, BUT, 99% of the time you will never be able to tell the difference between a raw and a jpg processed file. This is almost 100% the case when looking at pics on a monitor or tv screen. Prints can be more iffy but most of those problems are from your printer, printer set up and so on. Prints are [almost] a thing of the past. Few pictures are printed any more, and unless you are doing crazy stuff in PS, the print will be just fine, particularly if sent out to a print shop.

be sure to check their system requirements - you need a fairly new multicore processor and 2Gb video card - they list specific cards that fit minimum requirements - my 2015 MacBook Pro doesn't

I looked at the date and it is not April 1! So it must be another bright idea from marketing.

Most better scanners record 16 bits per color channel (48 bits per pixel) in TIFF format. That’s really plenty.

If you want a raw file, whip out your camera, macro lens, and a precision copy setup. That’s what I do for film.

My original reply went into cyberspace... The original file is the best representation of data you have. Any other juju can 'change' it, to highlight whatever parts you might want to 'improve'.

Adding information that isn't in the original may improve the appearance, but should be regarded as such. It is unlikely that the conversion will accommodate subtle lighting in some obscure areas.

With a trial period, check the feature with images having unusual lighting or highlights and see how it works. Caveat emptor...

So with trial version do some experiments. Camera on tripod. Well lit and colorful subjects.

Take picture using RAW + JPEG. Use Topaz to convert the JPEG version to RAW. Compare to original RAW version from camera. See if you notice any differences.

Since pictures was taken at the same time there should be no lighting difference to skew result. So comparison would be valid.

A lot of people said similar things about Photoshop v 1.0. Do you still have a rotary dial phone that you use to answer your pager signal while watching your b/w tv?

Actually, Clear Image Zoom is not using AI. It is only math algorithms where it computes new pixels from a certain number of neighboring pixels. Just a basic resizing program. And it does resize very rapidly.


I think you should read up more on CIZ - AFAIK, it is closer to AI than not - and is most certainly proprietary to Sony !

Although it does not transform jpgs into raw, Photoshop Elements (and I imagine Photoshop as well) will open a jpg in ACR and you can apply edits only possible in ACR, then take the image back to PSE or PS and finish editing.
I'd be curious to see a comparison between PSE Open as ACR, and the process used by Topaz, in an actual photo.

Get Pro Camera for an iPhone. It lets you shoot in RAW.
