convert DNG to TIFF, good or dumb idea?

I open DNG images in CS3,

do whatever corrections need to be done on the image,

add metadata into File Info ....

re number the image to my file number,

up sample a bit because I need to for my purposes,

and then save the image to a TIFF file,

from which I make a Hi Res JPEG,

and also a LO Res JPEG which is used for editing.

 

Finally, I discard the DNG file.

 

Am I crazy?

The same as you - I'm looking at DNGs that have been pushed though the Adobe DNG converter. Does that make a difference?.

 

Weird. I use the Image Capture tool to bring DNGs in. But, I just tested dragging and dropping a DNG (untouched) from the M8's memory card--still good. So, you're right, it must have something to do with the Adobe DNG format.

I guess I think of the DNG file as unfinished. The numbered tiff when it's finished is what I will be working with.

Perhaps it would be good to just remumber the DNG and save it as I do with Raw scans ?

 

Rafael,

 

Never throw your DNGs away! :) Case in point--Aperture 1.5 to Aperture 2.0. They introduced a new RAW converter with new features in 2.0. I could just open up year-old DNGs and tinker on them with the new tools, non-destructively, to get a different look!

 

Thanks,

Will

Ok Will

 

Good Point.

 

I will save the DNG I will put the DNG # into the metadata after my number so I can retriev it

 

thanks!

No- You must store the DNG like you would put your negatives in a negative album.

When you have converted the DNG to Tiff you have alraedy altered the basic data of your camera output. If you throw that away you can never recover those data.

If I right click and select 'Get Info' I can see a thumbnail, but not in the folder itself.

 

My wife is on the macbook with the same sofware version, and she can see the DNG'S in the finder.

 

Did you try this:

 

open a finder folder with DNG's

from the 'view' menu choose 'view options'

check the box called 'show preview'

 

edit: sorry, you have to check all three boxes to get the most fuctionality.

 

Hope this helps.

Like others, I shoot the DNG + JPG (hi quality) option. Store the DNG's both where you have room, and where they can also be archived.

 

Then import all the JPG's to Iphoto for general viewing, web transmittal, and reasonable printing.

 

The DNG's can also be loaded into Iphoto, but I prefer to see and modify them in C1.

 

Iphoto will print a rather luscious B/W JPG up to 8x10 without a problem. Looks very good too.

 

THis workflow seems to do well for both casual work and for finer quality work. The remote storage of the DNG means the Mac Book isn't choking on massive numbers of raw files.

 

The number of times one has to go "get" the raw file are few, but you want it securely when/if you need it.

 

Hope this helps.

For your consideration, there is a whole school of people who follow the DAM (Digital Asset Management) workflow with a highly popular and useful book by the same name which centers on the DNG as the main way of archiving/organizing an extensive photo library. I believe some of the chapters many be available online and you can read all the pros and cons behind why DNG is the future.

 

Best regards,

Arif
