Scaling down Mark IV files?

->> I shot a State Tournament last week-end and sold team CD's. Well I had the Mark IV set to the large file size and each file is about 10MB.
This has resulted in using many more disks than I had planned and time to make.
This is not a huge issue but what would happen if I just batched a resave in a PS action to say 8?
Would the quality of the image suffer, be noticed?

->> Are you expecting them to be making 40x60 prints of every image?
Rather than saving at 8, why not just batch resize them to something more manageable like 2000 pixels on the long side - unless it's intended for viewing only, then you could go down around 600-800 pixels? |

->> Mark,
No 40x60 is not resonable, I did this all the time with my mark II and the files were 2-3MB and were fine.
even 5MB each is fine
How would you do this, I am setting up an action in PS...?

->> Jim,
If you have Photo Mechanic, you can use the save as function to resize your files. It works great!

| ->> I've been having great results shooting the 1D4 on M1 Jpeg when I'm not concerned about massive prints. I think it cuts the file down to about 12 megapixels or so, with a file size around 5-8mb. Fewer pixels but still plenty for cropping. Easier on the disk space than the 16mp files. |

->> A simple solution would to be: Photoshop>Image>Image Size>Resolution >change to 150 or 200 or whatever size you need > save as (keep the jpeg at max)
The reason you want to use Resolution is because you may have images that are vertical and some that are horizontal while you are running your action...if you use a pixel dimension it gets crazy ;) This should cut you size and leave the image looking great. Don't think you should have to unsharp mask, but use discretion.
Cheers,

| ->> As Daniel said, Photo Mechanic works great for this. Highlight all the files (you want) on the "contact sheet" and do Control+S (shortcut for save). The next window lets you set a "box" size (to accommodate horizontal and vertical) and resolution, and create a new folder. You can rename them here, too. |

->> I would do a batch process in DPP. Simply select all the images you want, set the destination, set desired resolution, click resize and lock ratio, then set the desired dimension of the width or height (of the first image selected). It will automatically adjust for orientation.
You can rename and sequence if desired as well. |

->> OK I just created a PS action that saves these at level 9 rather than 12 in PS.
Original file details, based on PS Image size, 3264x4896, width 45.33 height 68 resolution 72 File size according to windows explorer 10,571
Same file saved as level 9 all the above is the same except file size became 2,541
What are your thoughts on this? How does this degrade the image

->> Jim... with all due respect, you're not listening to the advice being given. Dimensions, pixels, and IQ are all different animals. You'll want to toy with dimensions and pixels before changing the IQ setting. Best way to set the analogy... what would you rather your customer have... a stellar looking 4 x 6 or a crappy 40 x 60. Hypothetical response... "Well, I don't think a majority of my customers are going to print 40 x 60."
Exactly. That's what we are trying to say. But since on the subject of JPG quality... level 8 is fine. Set an action for 4 x 6, 300 ppi, at level 8 and you'll be golden. |

->> In Photoshop, go to File>Scripts>Image Processor. You can select what folder of files you want to process, the type of files you want to create (tiff, jpg, etc), maximum pixels for the height and width of the images, compression level for jpgs, and more. Then, hit "run" and let PS do its thing.
You can create an action, as you have done, but it's already been done for you, with more options, in the Image Processor script.
If you want to resize the photos using the Image Processor, you set the maximum pixels for the height and the width (enter the same number for both). The aspect ratio is maintained, regardless of whether the photo is landscape or portrait orientation. |

| ->> photo mechanic is much faster and does the same thing as making an action in photoshop |

| ->> Why not just burn them to a DVD instead of a CD? Lots more capacity at minimal cost/time consumption. |

->> Thanks for all the options and I investigated all of them and based on my trials I have found Alan's recommendation of using the built in script to be the fastest, most user friendly method over the PS action I came up with and the PM options.
This is actually much faster than PM from what I can tell, I am currently running this on another PC, 1811 files in total. The current modifications start with changing the pixel size of each image from my mark IV file size of 3264X4896 to my old mark IIN file sizes of 2336X3504 AND scaled the image quality to 11. This will be exactly how I have done hundreds of these in the past and no complaints. The file size has gone from 8-10MB to 1.8-2.6MB or so. I just processed to 12x18 one with each file pre and post conversion and no difference in my critcal eye.
If you see anything wrong with this please let me know!
Some repsonses:
Paul, I was not clear prior to posting the comment about the action I created and was refering to in my second post, I did the PM approach prior to posting this and thought that just changing the IQ would do it, not so.
Alan, Thanks for the heads up on the script looks like this is the way to go.
Chuck, Based on my experience the PS script is a fair amount faster than PM, might want to check it out.
Jay, I used the term "CD" in general and always planned on using DVD's BUT 1811 files at 10MB is 5 DVD's or so and that times 14 players is 70 disks to burn, huge amount of time compared to 14 or 28.
Any comments always welcome!!
