Does Picasa develop raw files? I was experimenting with my camera the other day, taking pictures in raw, and when I uploaded them to my computer via the card reader, sure enough, they came up with an option to send them to Picasa for processing.
And if so....how good is it? Thanks.

It seems to. I shoot 100% RAW with my Canon G9 and my two Canon DSLRs, and Picasa seems to process them just the same way that it processes JPEGs.

But I don't normally use Picasa to process my RAW images. I use the Adobe Camera Raw (ACR) converter that is in PhotoShop CS3, because it has more controls. I have Picasa on my netbook to take a quick look at pics in the field, but I don't process them for real until I get them home on my desktop machine.

It isn't bad, but if you are interested in processing RAW, buying a program like PhotoShop Elements (which has the same ACR that full PhotoShop CS has) is worth the investment. Picasa is fine for doing a quick touchup of images, but other programs offer a lot more control.

You can always buy a more powerful program later to process your RAW files. The most important thing, IMO, to shoot RAW for any images that have any chance of having lasting value. You can revisit the RAW files in the future to process them with a better RAW program, if needed.

Or shoot RAW+JPEG and then weed out the clunkers, to get the best of both worlds. You'll have JPEGs for immediate use, and will still have the RAW files to process, for the ones that are really valuable.

Back to Picasa. Where RAW files are most useful (compared to JPEGs from the camera) is if you need to dig detail out of the shadows. Or rescue detail from blown highlights. Picasa's "Fill Light" control digs detail out of the shadows if it operates on the image data when it is still in the RAW state. What I don't know is if Picasa internally converts to JPEG immediately and then works on the converted data. If it doesn't then its RAW conversion isn't particularly meaningful--a RAW converter needs to work on the image data when it is still in the RAW state before you will get a meaningful improvement (compared to processing a JPEG.)

Picasa doesn't offer anything to let you rescue blown highlights. This is Picasa's biggest limitation, IMO.

Adobe offers all their software in demo mode, so you can install it and it is fully functional for 30 days. So you can see if it is worth buying.

Without a doubt it processes RAW. But I don't like any software program offering to copy files files from media card to hard disk for you. You have more control copying those yourself. I refuse to let any program put another tray icon and a process to monitor anything and everything you stick into a USB port because it fights with the other program that monitors your USB port.

All the RAW processors don't damage RAW files - in general they offer to output intermediate or final JPEGs.

Picasa offers you a one-stop shop at RAW processing - you look at the thumbnails move a few sliders and voila, it's done. And it has no onerous licence restrictions like Adobe likes to implement on their products - Picasa is free and can be installed on any machine you want.

Yes.

8-)

Picasa's biggest limitations for me are:

a. it doesn't offer output to JPEG for 95% image quality compression setting - it offers a few simple to understand settings but not a numeric measure.

b. the sharpening has been much improved over the original simply yes or no. But it's not a high class tool.

c. there is no vignetting effect - vignetting - there are other garish effects which are too obvious

d. the soft focus effect isn't a classy tool - it only offers a circular shape and is again too obvious

but the biggest pain I have since 3.0 came out is that Picasa every so often loses all thumbnails, then it starts building it's database and misses some pics and captions and thumbnails and effects get mixed up.....

A serious RAW convertor and post processing program is worth having. Picasa, if it does not have bugs is just easy to get going and good enough for web posting.

My opinion is that if you are going to use Picasa to process RAW files, you should just shoot JPEG as most cameras will do a better job of converting RAW to JPEG than Picasa.

Chances are if your camera came with the ability to shoot RAW then it also came with some way of converting RAW to JPEG. Whatever that program is, it will probably be far superior to Picasa. If you are strapped for money, I would just do that.

Another low budget alternative is Raw Therapee, which is a free downloadable RAW to JPEG converter. I have played with it some and it is surprisingly capable for a free piece of software. Unlike Picasa, it will give you better results than camera generated JPEGs.
 
Sorry but I don't currently subscribe to a web photo hosting service. I have thousands of JPEG photos that were generated by the camera but none at present that were converted with Picasa. The results I got on initial trials convinced me that it was not the right thing to do. I do use Picasa to sort my photos and I have even used it to enhance a few JPEGS with some success. It just doesn't have the features that a dedicated photo editing program does.

It is easy enough for anyone to conduct an experiment to see whether Picasa is any good for RAW conversion. Just shoot RAW + JPEG fine mode and do the conversions yourself and compare. If you are satisfied with the result then use it. I did that and was not impressed. The colors were way off and the details were worse than JPEGs shot at the same time. I am not interested in doing a conversion where I have to spend the next several minutes correcting the mess Picasa made during the conversion. There has to be a reason why the vast majority of people spend good money to get a RAW converter rather than use Picasa. What I don't understand is why the guy who wrote RAW Therapee is giving it away. The performance of that program rivals or sometimes exceeds that of ACR in my experiments. If you want a free program, that is the best one I have found.

That's one advantage of Picasa desktop software - it can seamlessly upload to Picasaweb, to Flickr and to Facebook and to seamlessly email them.

I have hundreds maybe thousands of RAW files from Kodak P880 and two Oly DSLRS - for the most part "not for printing" I use Picasa to review them, to catalogue them, to tweak them, to email them at 800x600, to upload directly or export them at 1024 size to the web.

As I said before, there are limitations in this tool - it is not designed to be a purpose built RAW processor. You cannot set the JPEG quality to 95% image quality, it does none of the fancy Photoshop features (but that isn't RAW conversion). But any RAW processor DOES NOT DAMAGE THE RAW - they produce JPEGS. Using Picasa does not preclude or exclude you using a purpose built RAW processor later for specific photos.

If you compare convenience of coming back from a RAW shoot and cataloguing, tweaking 100 RAW, for me, Picasa wins in convenience. If I want to concentrate on a few RAW files for printing, then I use a purpose built processor.

If you compare RAW vs JPEG from the camera:

1. Some cameras have a really good JPEG engine. My Kodak P880 does and my Oly DSLRs do. So whether you use Picasa or Lightroom, it takes effort or stored skills / settings to even get close to the JPEG "pop"

2. However, JPEGs esp in my Oly 510 DSLR, has a steep contrast curve baked in. If the JPEG has burnt highlights about 1 stop over, Picasa + RAW will meet the challenge better.

3. JPEGs are notoriously hard to colour balance if you shoot mixed lighting or the colour balance is wrong because the colour balance is baked in. Picasa + RAW works fine.

If you have to correct the mess that Picasa made that advantage is completely lost.
why the vast majority of people spend good money to get a RAW
converter rather than use Picasa. What I don't understand is why the

program rivals or sometimes exceeds that of ACR in my experiments. If

If you work hard in Lightroom, ACR, Raw Therapee, Silky Pix, you can equal or easily better Picasa. In particular, if you want to print, that is the way to go.

If you want to quickly catalogue shots, post to the web with low amount of work, and time spent say about 5 secs a shot and put it on a web host or email it or make JPEGs for display on flat panels, screens and TV (I repeat, not for printing), Picasa reduces the amount of work that you have to do.

Here are recent shots:

picasa will convert a raw to jpeg, which you can then edit. You can also edit the raw but only with the same tools as the jpeg. In p-shop and other programs, you can do a lot more, reset exposure, white balance, sharpen etc. In most newer cams, if you take a good pic, it gets real hard to manually outdo the cam in a raw conversion, and the differences are subtle and may be "better" or "worse" depending on personal prefs. If you blow the pic with bad exposure or wrong white balance, you can "re-take" the pic in raw by changing the settings, and maybe save it, but not with picasa. I actually use photo shop to do the conversion, and end up tweeking the jpeg in picasa because I get good results with just the 3 or 4 sliders on the edit page. Most of the time the jpegs out of the cam are just fine tho.

cam jpeg, blown highlights



picasa raw conversion and edit



photo shop raw conversion



In these pics the settings were applied to get the green boxwood to the left of the pot to show up some, without making the pot over exposed. Its the same pic, jpeg from the cam, and raw conversion with both programs, on the same file. the photo shop did the best IMO. To tone down the exposure on the cam jpeg, the boxwood disappears. Both raw conversions brought it out while "dimming" the pot.
