Urgent Help Required Re Image Quality
« on: October 17, 2013, 08:40:42 PM »
Im doing a photo shoot tomorrow at a corporate event for work. I want to be able to take as many images as possible, and can't decide on if I should use JPEG or RAW. If I do go for RAW (the conversion for me to DNG is a pain and time consuming) does it really matter what RAW quality I chooses? RAW, M Raw or S Raw? I always resize them anyway. Can someone explain the differences?

I've heard you regularly complain that you ran out of power, so make darn sure your camera battery is charged.

You can get a lot more Jpegs on your memory card so if you want to shoot a lot, I'd say go for that.

Can't advice on RAW.

Have a great day, and don't get seduced by the wine till the shots are in the can.

I have worked with raw files but always shoot JPEG and RAW as a setting, you do need a lot of memory and cards. Raw offers the optimum in post production but it depends I suppose where the pictures are ending up and perhaps JPEG is good enough.

Like a photographic negative, a raw digital image may have a wider dynamic range or color it preserves most of the information of the captured image. The purpose of raw image formats is to save, with minimum loss of information.

Perhaps someone who only uses raw is better qualified to answer this as the opinion is only mine.

Raw size? Raw is raw when shooting with Nikon - no such thing as MRaw or S raw for me ??? The size of the images is shaded out and only apply to jpegs.

For work shots I always shoot raw - in fact I shoot raw 99.99 %  of the time to have maximum potential for editing. If worried about your computing power and serious about photography you need to change your computer. Raw will help save the odd shot you got wrong under pressure and give you latitude.  I use jpegs + raw if images have to go straight out in a press release.

S-RAW

Introduced with the EOS-1D Mark III, S-RAW provides all the advantages of a RAW file, but in a smaller file size. An S-RAW file has approximately one-fourth the pixel count and approximately half the file size of a RAW image. Just like RAW images, S-RAW images can be adjusted and processed with Digital Photo Professional software (supplied with the camera). S-RAW will appeal to wedding photographers, for example, who do not need full resolution for wedding candids, but who do need the post-production control RAW offers.

Advantages•Smaller file size than RAW (so more images can be captured to a media card)

Disadvantages•Lower resolution than RAW


M-RAW

Introduced with the EOS 7D, and also on the EOS-1D Mark IV, M-RAW provides all the advantages of a RAW file, but in a smaller file size. Depending on the camera an M-RAW file has approximately between 55-60% of the pixel count and approximately two thirds the file size of a RAW image. Like RAW images, M-RAW images can be adjusted and processed with Canon’s Digital Photo Professional software (free in the box with the camera). Shooting M-RAW files might appeal to wedding photographers who don’t need full resolution for wedding candids, but who do want the post-production control that RAW offers. It could also be of use to sports/action photographers who will get an increase in the number of frames when shooting in bursts due to using a smaller file size. M-RAW is also worth considering if you are not planning to make prints larger than A3 size.

Advantages•Smaller file size than RAW (so more images can be captured to a media card).
•Increased burst shooting possibilities.

Disadvantages•Lower resolution than RAW.



To be honest I would shoot Jpeg for your event tomorrow, as it's quicker and allows you to take more shots. Jpeg isn't as bad as some people make out and making adjustments doesn't destroy the finished Jpeg too much.  :tup:

I live and learn - quite why Canon would do smaller sized raws is beyond me - you shoot raw for the breadth of content. certainly shoot in jpeg rather than reduced size raw and I forgot to say - good luck!

I think the best comparison it to recent versions of Adobe's DNG format.  You can have full size and you can have a smaller version that uses a lossy compression.  So some data is lost but you still have more than JPG would give.

Having discussed what the client wanted when I got there, I decided JPEG would suffice. Took about 300 images in total so could have did RAW all on one memory card, but never mind. At leastI don't need to convert to DNG first.

Thanks for your comments and suggestions.

I assume you are converting to DNG because your software is too old to support you camera? If that is the case, I would really recommend you upgrade or get new software. LR 5 is not that expensive (Compared to what it used to be at least!) and should support all current cameras.

Had a really good time, thanks guys. Its not software I need to upgrade, its hardware. Im on an old Mac Pro and thats why I have to convert to DNG. Time consuming but I manage ok.
