The Ultimate All-in-One Card Reader for The New iPadApril 17, 2012 | by: Chris Chang | Apple |
The new iPad features a huge jump in screen resolution with the Retina display, making the iPad perfect for watching 1080p video and viewing photos with incredibly high megapixel amounts.
So what if you are a professional photographer or cinematographer and you would like to make full use of your new iPad? Well, along with the new all-in-one card reader, you can transfer images and videos from your CF card or SD card to the iPad. Preview them in the field, edit the photos using iPhoto, or edit the footage with iMovie.
Using In The Field (for photographers)
With the all-in-one card reader, you can access your images in the field and view them directly from your camera’s CF/SD card on the new iPad. We tried to shoot 14-bit uncompressed RAW straight to a CF card on the D800. And import the 36 megapixel uncompressed RAW files into the iPad. We found out that a full resolution RAW can be imported into the iPad, and thus, we are able to edit a 36 megapixel RAW image using iPhoto on the iPad.
Then we move on and convert the 36 megapixel 14-bit uncompressed RAW file into JPEG using iPhoto, and the process took us less than 20 seconds. Our 36 megapixel RAW file gets resized down to a 11 megapixel JPEG file.
Work with RAW Files
We also tried to import 14-bit lossless compressed RAW files from the D3X, and the all-in-one card reader had no issue reading the RAW files from D3X. However, some of the kinks we encountered during our testing is that when we import RAW images from Canon 5D Mark III, the RAW files become JPEGs after the import. And they are resized down to 5.5 megapixel. When we are importing the RAW images from the D800 and D3X, they are not resized in the import process.
Publish Photos Online
If you upload a 14-bit uncompressed 36 megapixel RAW image to Flickr from the iPad, it will be resized down to 11-megapixel JPEG. If you upload it to FaceBook, it will be resized down to 2048 x 1637 px. And lastly, if you upload it to Twitter, it will be resized down to 512 x 342 px.
Using In The Field (for cinematographers)
For the video part, we have to focus on the new iPad. Comparing to the iPad 2, the new iPad has more powerful GPU, and doubled system RAM. These two features actually benefit cinematographers. With the all-in-one card reader, we manage to import 1080p footage that was recorded using the ALL-I codec on 5D Mark III. And 1080p footage from Nikon D800.
Speaking of using the card reader in the field, here’s an example. If you are covering an event, let’s say the NAB show, where you will be doing some hands-on video with new video camera equipment that are displayed on the floor, the all-in-one card reader will be a useful tool for you to import videos into an iPad and edit them with iMovie.
- Medium 640 x 360 30fps 44.1kHz
- Large 960 x 540 30 fps 44.1kHz
- HD 1280 x 760 30 fps 44.1kHz
Transfer Times and Compatibility
One big concern for photographers hoping to use the iPad in the field is speed. If you want to use an iPad as a place to offload files during a shoot (perhaps to give clients an instant preview of images on a bigger screen), it’s important that the iPad transfer times be reasonable. So we tested the time required for images to be imported from different cameras and memory cards, for storage and display on the new iPad. Check out the lengthy video of the test below.
And the following table shows the time for importing JPEG images in different amount of megapixel.
Next, you may wonder why it takes such a short time to import 12 megapixel photos. Well, we discovered that the iPad photo app can only handle JPEG images up to 19 megapixel, just like the iPhoto app supporting images up to 19 megapixel. JPEG images that are higher than 19 megapixel will be resized during the import process. Thus it takes significantly longer time for the card reader and iPad to import 22 megapixel and 36 megapixel JPEG images. Here’s the calculation:
- 36 megapixel JPEG image will be resized down to 9 megapixel.
- 22 megapixel JPEG image will be resized down to 5.5 megapixel.
There’s good and bad for Apple’s iOS “security” file system restrictions. The good: Not necessary to do a lengthy import onto your iPad, iOS will resize JPEG files that are higher than 19 megapixel, thus smaller file size for faster transfer. The bad: You will lose image quality when iOS resizes your 22, 24 or 36 megapixel JPEG images, but that doesn’t actually matter when you are just previewing the photos on a bigger screen in the field. Your original JPEG images still live on your memory card.
Then, we tested 14-bit uncompressed RAW from the D800 and 14-bit lossless compressed RAW from the D3X. As you can see, the time for importing 14-bit lossless compressed RAW is similar to importing uncompressed RAW, despite lower megapixel and file size. Perhaps due to the need of decompressing the compressed file, it requires more time to import lossless compressed RAW.
As for the process of importing 14-bit RAW + 36MP JPEG into the new iPad, it really takes a long time to transfer the files. Yes, both JPEG and RAW will be imported, but the two files will be represented by one optimized JPEG. Both original files will be stored on the iPad and sync with your computer. So, if you shoot and import RAW + JPEG, the stock Photo app will only allow you to preview the JPEG, you can’t preview the RAW file at all. And the JPEG image will be resized if it overshoots 19 megapixel, and that’s the optimized JPEG we’re talking about.
And the following table gives you a clearer look at the test results.
As for compatibility, here’s the list of the memory cards we have tried:
- SanDisk Extreme Pro 600X 16GB CompactFlash
- SanDisk Ultra 30MB/s 4GB CompactFlash
- Transcend 133X 4GB CompactFlash
- Transcend 400X 32GB CompactFlash
- SanDisk Extreme Pro UHS-I 16GB SDHC
- Transcend Class 10 8GB SDHC
- Toshiba Class 10 16GB SDHC
- Pretec Class 16 16GB SDHC
- Verbatim Class 4 4GB microSDHC
- Lexar Class 4 4GB microSDHC
All of the above cards were compatible. In a situation, the iPad’s import screen refused to appear when the Transcend 400X 32GB CF card and the SanDisk Extreme Pro 600X 16GB CF card were in the all-in-one card reader. The problem is that there’s no DCIM folder at the root level of the card. So, we manually create a folder named ‘DCIM’ and boom! The iPad import screen appears and we see thumbnails appearing right in front of us.
Look and Feel of The All-in-one Card Reader
For photographers, they can shoot RAW files and import them into the new iPad with the all-in-one card reader. Then they can open the RAW files and edit them right on the spot. The best part? The RAW file will not be resized or optimized during the import process. So you can go ahead and edit a full resolution image. The whole process allows a photographer to view, manipulate, and send off photos while still in the field.
For cinematographers who are using DSLRs for filmmaking, the all-in-one carder allows them to import footage directly from the memory card into the iPad to view the footage on a bigger screen. What’s more, it’s possible to do editing in iMovie, which is useful for journalists when they are covering a trade show. Shoot the video, import it to iPad, edit it, and upload it to YouTube or Vimeo. It may be useful for wedding cinematographers too, especially doing a same-day edit.
You can find the all-in-one card reader over at M.I.C. Store, for just $32.90. (SOLD)
