Testing JPG vs RAW

Most of you know JPG, it’s the most popular image file format and what you get from most digital cameras. Professional and prosumer cameras have the option of producing image in RAW format, which is an unprocessed format akin to having a digital negative. With JPG, the camera basically does all the processing for you, picking exposure, white balance, sharpness, contrast, etc. RAW gives the photographer a bit more control and flexibility since the camera doesn’t really attribute those parameters and the photographer can tweak it at will in the post-processing stage. The biggest disadvantage of RAW is that it produces much larger images. On my 10 megapixels DLSR that means if I shot the at highest quality JPG I could fit 132 pictures and at RAW 82. It also requires a bit more time post processing afterwards. Since I have the possibility to shoot RAW+JPG, I tried that today to compare.

Here’s what I got. The top picture was shot as JPG and later cropped and adjusted a bit. The bottom one is the RAW image, post processed and cropped similarly.

Hmmm, it looks like I could have worked on the contrast of the RAW picture better… What’s your impression?

É impressão minha ou a RAW apresenta mais detalhes na espuma do café?…

Busy weekend ahead

The weekend is promising – we want to check out at least two festivals: The Taste of Little Italy and the Blues Fest at the Distillery District. But first, we head out to Kensington Market and the best coffee in the city…

Here’s where I go, from the Toronto Life magazine:

Casa Acoreana
Louie Pavao founded this corner spot as a fruit stand 41 years ago; his four sons (Victor, John, Ozzie and Mike) now preside over the café and bulk shop with familial pride. More shack than shop, it serves up the perfect latte (potent and smooth); and with hundreds of different kinds of tea, coffee and spice filling pretty glass jars, the old-fashioned general store pops with colour. A dreamscape for the candy cognoscenti, Acoreana rescues many classics (Tunnock’s Snowballs, Thrills gum) from extinction.
