what is RAW all about? #mamarazzi #photography101

This week i thought i would muse on something a little more about quality settings within your camera and details about image file format….

yeah i so know that half of you have just fallen asleep…ha!

Anyways i have been asked about RAW before so i thought i would mention it.

Most of your DLSR’s will be able to give you two choices of what mode you want to shoot your images in, what file format. The standard mode is JPEG, which a really useful file format. Its relatively small, simple to store, uploads into all editing programs, can be uploaded to the internet and sent in email.

So why would you consider something else, if you have this super duper fits all format?

Well a raw file is basically giving you more information in your file and therefore gives you more options of what you can do with your image in post processing. For example you can restore some detail in a blown out image or bring in some light to a dark image, change your white balance or make some more sophisticated photoshop edits.

So why do any of us shoot JPEG then if RAW gives us so much more. Well RAW files are mahoooooosive. They take up some serious space, your storage space is just going to get eaten up with raw files. Ask my OH how many times he tells me to delete some files as the hard drives (and i have three) are getting full. Also you might have to buy more software to be able to process raw files. Software companies such as adobe do not always have the standard format for certain raw files form certain cameras, particularly if you have older software and you are buying a newer camera.

So i guess the thing is to weigh up whats more important to you, space or image data and control. You can even experiment a little as a lot of cameras will allow you to shoot in raw and jpeg. So you can do a bit of both. That will suck your memory cards though. Remember if you have a 4gb memory card then you won’t be able to store as many raw on that card as you will jpeg.

So..how to change the image quality. This is on a canon camera. Should be easy to navigate to on other makes. Im making no comment about what camera is best. The photographer takes the picture remember!

You need your menu, go into quality and you see the icon that looks like a little wedge of a cheese. 🙂

There you can see the options you can go for.

If you are shooting in raw, make sure you have the software to read and use those files. So might be worth shooting jpeg and raw initially. In photoshop your raw file will be loaded into adobe raw, which is fabulous tool for some great editing options without going into full photohsop.

So a little example, this is just to demonstrate what you can do in adobe raw..so im not going to go into photoshop ..another time 😉

so this is my original image….

 

 

then taking it into adobe raw, if you have photoshop the image should open in adobe raw….looking a little something like this, you can see the image, the histogram on the left which shows you colour range through from darks to lights and then your options for editing down the side. You can see where there is red masking..that is where the pixels are blown out. It was direct sun (behind her).

 

on this one i have slid the ‘recovery’ slider which has drawn back some of those blown put pixels, you can see the red masked areas have gotten a little smaller? yes?

The square box is also where i will crop the image to.

 

Then i have slid up a little bit of vibrancy to make the colours pop a bit and used the ‘curves’  to bring a little bit of light into her face.

Ive also sharpened the image up a little.

 

This is the initial result. Now if you did that to a jpeg file, if its a lovely bright image like this where your camera and lens are not maxed out then it would be fine but if your camera is working pretty hard to get the light right and your ISO is high then editing your image may well leave it looking pretty grainy.

 

So what do you think? Have a play with it, see what you can do. Thats the brilliant brilliant thing about digital photography…you can just keep on trying without having to pay to develop a truck load of film.

Let me know how you get on.
