Digital photography: Shooting in RAW, TIFF or JPG?

Posted By on August 20, 2016

An aside … I spent my formative years engrossed in photography, back before it was digital and when "souping" film in a darkroom. Nowadays 90% of what I take is on a smartphone due to the simplicity and recent improvements in quality. Still, the best photographic images come from a quality lens and large sensor in the hands of a photographer who knows how to marry creativity and composition to the science of capturing light digitally. Part of that science is how to "save" the image after taking a photo … so here’s little advice from a professional in Melbourne Australia and shared on Mel365.com.

The question: How do you know when to use RAW, TIFF or JPG if you are taking more than smartphone pics?

Here’s how to get better photos out of your expensive DSLR and editing setup.

Levels of brightness
JPG is a 8-bit file which stores up to 256 levels of brightness. RAW is a 12-bit file, which stores up to 4096 levels of intensity. These are typically the two formats you are offered to save on a camera. What a difference!! In case you do some post processing, like HDR, raw format is the way to go, no question about.

Otherwise, just use JPG, easier. But remember once you have saved in JPG, you lost over 3800 levels of intensity that you could use in future, maybe in two years time, when you decide to start doing some post-processing, even things as easy as White Balance. As a long term solution I always suggest to go for RAW.

File compression
The JPG file is stored in compressed format and you will loose information. Just think about the over 3800 levels of intensity lost as a start, than lots of details, and …… The positive side is that your file may be a fifth in size compared to RAW.

So, if you have a small memory card or you are travelling and you don’t have too much memory left, than switch to JPG. My suggestion is just to upgrade to a bigger memory, nowadays it is so cheap, compared with the information you loose when shooting JPG.

Photo printing
Photos are made to be printed. Of course not all of them, only the nicest ones. Each end of the year organize a book with all the photos that you like, as in the old days when you were printing the photos once back from a holiday. Here is another fact, the printing industry works mostly on 8 bits.

Blurb, one of the best for printing books, uses either JPG or PNG, both 8-bits. So, again, if you shot and print, no post-processing, you may just be happy to use only the JPG format. Does printing at 16-bits make a difference? If you can find a place that prints 16-bits, give a try, and let me know what you think.

Your camera rules when shooting in JPG
When shooting we all pay most of our time, rightly enough, to the composition. There are however other technical decision to take as White Balance, Contrast, Saturation, Sharpness etc. If shooting in RAW you may be able to change them later in post production, if not happy with them.

Unfortunately when shooting in JPG you have a limited range of maneuverability. However you cannot make miracles, if the photo is either not in focus or not sharp, there is just no way to improve it. Read The importance of focusing: how to have it right and 6 suggestions for a sharp landscape photo for an in-depth analysis.

Displaying RAW files
You cannot view RAW files straight on your computer. You need to install a driver for that. However if you use Lightroom, Adobe Bridge or Photoshop, they all include the driver by default, usually.

If the camera is a new model, you may have to download the driver from the camera maker.

The annoying thing, in case you have a brand new camera, is that you may have to upgrade most of your software, therefore budget always some spare money for that.

Another way to go is to install the free DNG Converter from Adobe. This is a lossless raw image format which is recognized by any Adobe product.

The TIFF format
Here it is a new format, to make things even more confused, TIFF. This format is available as 8-bit or 16-bit. Once you have the RAW file and you want to process it, than the most natural thing is to convert it to TIFF 16-bit.

It will be a bigger container than needed, but no other solutions (12-bit TIFF does not exit!!). You can save it as TIFF 8-bits but you will loose some info of course. However, TIFF does a lossless compression, as opposite to JPG.

RAW files and Adobe Lightroom
The most famous software for photo archiving is probably Adobe Lightroom. This package includes also some post-production functionalities which, in full honesty, cover the needs of most amateur photographers.

The feature I love of this software is that it does not save my RAW files in any other format when I start working on the photos, it just saves the changes I do on the photo.

I this way I do not have any duplicated images. This is especially important nowadays with cameras shooting up to 50M saving on new Hard Disks purchase.

Who are these Minion characters?

I really don’t know who these Minion characters are, but admire the phenomenon and their “cuteness.” Frankly I’ve haven’t actually seen the movie … or is it movies plural by now? Anyway, seeing them creatively showing up on a corner at our local Delhi Garden Center puts me in a good mood — and that is worth something!

Again, $TWTR is great for traders, not so much for investors

If I were a bit more savvy and listened to my own advice, I would have traded Twitter ($TWTR) for a few dollars this week. On a downgrade to a SELL by Evercore ISI analyst Ken Sena, shareholders listened and poured their sell orders onto the exchanges after seeing shares climb the last few days on speculation and rumors.

Snapchat is poised to take more marketshare, Evercore ISI analyst said.

Shares of Twitter Inc. slumped 4.2% in midday trade Thursday, after the stock was downgraded to a rare sell rating from hold at Evercore ISI.

Evercore analyst Ken Sena said he turned bearish on the stock as the company appears to be adding broadcasting capabilities as a method of turning around the company. Sena says other social companies are already using broadcasting and other innovations more successfully and drawing in existing (TWTR) users and advertisers. Only 29 of the 665 companies covered by Evercore ISI analysts, or 4.4%, have sell ratings.

"We see more risk than reward, particularly ahead of Snapchat’s anticipated monetization ramp this fall," Sena wrote in a research note.

Twitter recently announced a deal to live stream National Football League games on the platform and has been rumored to be in talks with Apple Inc (http://www.marketwatch.com/story/twitter-shares-soar-after-report-of-apple-tv-talks-2016-08-15).(AAPL) to put a Twitter app on Apple TV. The company has also added Moments, which curates tweets and videos around a topic, and nonlinear timelines.

Sena said he believes innovations fall behind efforts from companies such as Snapchat, which has made changes to its chat function and Discover section, for publisher content.

He was "dismayed" with the company’s revenue forecast for the third quarter, which suggests midpoint growth of about 5%.

As Twitter’s user growth falls behind that of social networks, the analysts say the pricing of its advertisements remains too high.

Twitter shares have had a bumpy year, but they gained 17% over the past month, and have soared 37% over the past three months. The S&P 500 has gained 0.4% month-to-date and 7% in the past three months.

Sena attributes the recent gains to rumors that the company could get acquired by a larger company. But with the recent gains, he said the shares were trading "at or above" what Microsoft paid for LinkedIn, (http://www.marketwatch.com/story/microsoft-buys-linkedin-for-262-billion-2016-06-13) (http://www.marketwatch.com/story/microsoft-buys-linkedin-for-262-billion-2016-06-13) (http://www.marketwatch.com/story/microsoft-buys-linkedin-for-262-billion-2016-06-13) despite have revenue that is less recurring.

Floating cities could be a reality by 2020

Interesting concept — “Each floating city would be made up of 10 to 15 platforms that can house 20 people each, allowing for a total of 200 to 300 people.”

My eyes are open for an Approved Packard Service sign

Posted By on August 17, 2016

PackardServiceSign

A friend of mine, an automotive journalist, snapped this photo on his way across the country on Route 66 last week and Packard_Sign-Sept11_27ButI couldn’t help but crop and copy it for my blog – (above – thanks Wayne, not that you know I’m using your photo).  Although my garage shop is not quite ready for an Approved  Packard Service center sign, I do like it.

I have a few projects on the list before getting my dad’s 1958 Packard Hawk on the road again, so maybe I need a sign to instill a little more confidence?  (it is now my car, but I’ll always think of it as my dad’s car — as I should).

The complex but impressive 3 compressor Audi TDI diesel

Posted By on August 16, 2016

Audi SQ7 TDI
Audi’s 2017 SQ7 diesel TDI takes a new spin on hybrid vehicles by incorporating an electric compressor in addition to the already impressive 2 compressors (turbochargers). I’m not sure at what point technology goes too far in adding complexity but improving performance, but this is one impressive TDI! (link and video illustration below)

Our BMW X5 35d loves cheap diesel fuel ;-)

Posted By on August 14, 2016

First let me qualify, this is the discounted United Dairy Farmers (UDF – Mobil) price for diesel … but I’m not complaining about $2.14 either (current Aug 2016 price). It isn’t like we need an excuse to buy milkshakes, but their summer promotion in discounts fuel is the little push I need to bring home a milkshake. So far so we haven’t gone overboard, but since the promo end with summer, I’ll probably try for one more promo fill.

Archive: Birthday wishes to my wife Brenda – a day late!

Posted By on August 13, 2016

RichBrendaOnBrenichNo I didn’t forget my wife’s birthday … I just didn’t post anything on the blog until my son Taylor requested a photo of “both of us when we were his age.” After sending him this one for his Facebook page, kelleysislandaerialI figured that I might as well archive it here. We regularly sailed and anchored in the Lake Erie islands … and were particularly fond of the cove on Kelleys Island so as long as the wind was not from the north! (oh, the stories!)

Above is a Photo from our pre-kid days sailing Brenich out of Vermillion and Huron, OH on Lake Erie … and below MomH on Brenda’s birthday, August 12, 2016.

One of my long time customers is making a change

Posted By on August 12, 2016

Change can be depressing, especially when it comes to losing a longtime client that I now think of as friends like the folks at SummitSWCD in Akron. In this case there isn’t anything I can do since as voters in Summit County approved expanding the county’s data center andSummitSWCDwebsite information technology department. They will now be internalizing the webhosting that my company, Consolidated Printing and Publishing, has been doing for them over the years.

When I think about it, we go way back; I’ve been servicing their needs, including printing and webhosting for decades. They have made two building changes and I’ve made one when moving from Cuyahoga Falls to Cincinnati.

Back in 1987, when we moved into our newly remodeled Cuyahoga Falls building, pre-www (World Wide Web – that actually sounds funny to say nowadays), they were one of my first customers as it was a no-brainer to go after the business right across the street from me — their small office overlooked the Cuyahoga River and had a nice view. I remember when several of today’s long time employees were hired and am now watching them retire (in their 50s!!!)too early in the opinion of someone who works in the private sector. Initially most all their printing and graphics work sent over to me, because besides a typewriter and copy machine, their office didn’t have personal computers … still a fairly new technology. The mainstays for those of use in the printing business were the expendables like business cards, letterhead, envelopes and carbonless forms (a big deal getting rid of carbon paper). My bigger push were the regular newsletters (my mainstay) and helping customers learn to design and "pageset" their own monthly newsletter for us to print. The good ol’ days! 

Actually the "change" got me thinking about how "change" also got me started in business. ‘Back in the day,’ it was the opposite move. Many established companies were finding their antiquated "in-house" printshops too expensive. printingpress2colorThe capital nature of the equipment and the legacy cost of well compensated employees were an ideal place to cut for many bloated corporations looking to downsize … or to use a business correct term, "rightsize." It was a big cost saving to have lean companies handle the printing needs that the vastly improved Xerox machines (soon to have a ton of competition too) were not able to handle by the office staffs. It was a good to be able to grow a business while these companies were outsourcing.

Nothing stays the same though, as the last decade (along with a recession and a low growth recovery – see yesterday’s post), companies and organizations are finding that technology is making it easier and cost effective to bring much of what they were sending out back in house. And so the cycle goes.

Hopefully I’ll still keep my foot in the door at Summit SWCD as I’ll keep making my regular stops during my sales trips to northeast Ohio … besides, I do still handle a few of their print jobs, but I can tell … those days are likely numbered as well.
