Question about Konica Minolta DiMAGE A2 Digital Camera

4 Answers

RAW vs. JPEG

When I shoot RAW+JPEG with my Dimage A2 and compare them in Photoshop CS3, the RAW capture is way softer (less focused) than the JPEG. This is not the case with other digital cameras I've used. Is the Minolta applying that much sharpening to the JPEGS or doing a lot of processing that makes the JPEG so much clearer than the RAW file or is there a problem with my camera? I never noticed this before because I never shot RAW+JPEG before. I usually always shoot RAW but noticed a little more noise lately which I attributed to low light shots but then did a little experiment in good light using the RAW+JPEG capture and found this fairly obvious descrepency between the two files' quality. Can someone else with a Dimage A2 capture an image in RAW+JPEG, compare them and see if they find the same quality issue. With post processing I can bring the RAW up to or surpass the JPEG quality but shouldn't the RAW file start out better? I just need to know if my camera needs repairing before I spend $200 for repairs when this problem may just be an inherent characteristic of the Dimage A2.

    I understand what you are saying but would still like to know if my Minolta Dimage A2 has a problem. If it has a problem recording the RAW data it may also have a problem correctly recording the JPEG data. If, in fact, having RAW data that looks more softly focused than JPEG data is normal for Dimage A2 files opened in Photoshop CS3, than I have no problem.
    Can someone who has this camera shoot a RAW+JPEG and open them in CS3 or CS2 without any processing, compare them and tell me what they find?
    I agree with what you say about non-standard file formats for RAW files. When I work with RAW files the first thing I do is convert them all to the DNG file format which is a universally standard format.
    Digital cameras have come a long way and continue to improve. Although controversial, many experts believe they will surpass film cameras if they haven't already since they have the ability to capture more visible colors and tonalities.
    The funny thing is, if you attend almost any college level, digital photography class, they stress to shoot only in RAW.

    I received some excellent information regarding RAW vs. JPEG but not an answer to my problem. Does my Minolta Dimage A2 digital camera need repairing due to the fact that my RAW files look much less focused than my JPEG files before any post processing has been done. Is there anyone out there with this camera that can shoot a RAW+JEPG, compare the two in Photoshop CS2 or 3 without processing and tell me if this is just an inherent characteristic of this camera. I don't want to spend $200+ to fix a problem that may not exist. I know with other digital cameras (Canon D40, Canon G9) the RAW file is as clear as the JPEG before any processing.

    Thanks eagle 338, but where did you get this information. I've read articles stating that RAW, when converted with Adobe Photoshop ACR, is the highest quality for this camera. Seehttp://www.dpreview.com/reviews/konicami...

Hi quickshot.. This is not a problem with the caamera.. Raw images are for low quality in this make. Thequality of images in different formats is as follows:
CCD-RAW, TIFF, RAW+JPEG, Extra Fine JPEG

You might have a hard time geting a good solid ansver to your problem. I don't think there are many experts here with the exact same camera.

I think there is noting wrong with your camera, its a simple difrence between formats, You can apply sharpness in photoshop to your images if required. The image might be a little out of focus maybe?

If you go to a camera shop and ask if you can take a raw shot and then view it on a pc in the shop and look at the difrences.

To me it seems like a small adjustment is needed somewhere noting serious wrong.

Im here to help, if you need anything else or want do discuss this further let me know.

D70s I shoot raw. Thumbnail picture on LCD is ok. when downloaded to computer have picture is perfect other half out of focus and look like ribbon or rainbow?


When you are using the raw format, you are also taking a jpeg basic photo. The camera display on;y show the jpeg. Most windows programs only show jpg also. In order to view the raw files, you must use s/w capable, such as Photoshop or the s/w that came with the Nikon (Picture View, I think/ Compare both jpg and raw files. If they both exhibit the same anomoly, than more than likely you have a dirty or bad CCD sensor.

Camera RAW and PhotoShop CS3


To start, before building an action or a droplet to convert from Raw, you need at least either the RAW plugin, or the photoshop lightroom plugin, depending on the version of Photoshop. I assume you have the plugin installed on your Photoshop. See: Adobe - Adobe Photoshop CS4: Digital camera raw file support.

A better choice would be having the Nikon Capture NX , that give you the option to work on the native RAW format from Nikon.

Once you have installed a plugin to manage RAW format files you can record an action or droplet to automate the process. If youj want more automation, you set an action first, as a batch process to do action on a single file, then build a droplet on the action batch file. A droplet will give more automation, since droplets can be activated by dropping a folder of images onto that specific Droplet Process, and they will apply the batch process to all the files contained in the folder.

The way you build the batch action depends much on the version of Photoshop you are using and on the plugin used. Here an example using Adobe PS CS2 and camera Raw plugin: Raw Format Workflow with Adobe Bridge .

The action can be saved using the recorder, so that the procedure will de quite instinctive. See the tutorials below for step-by-step instructions.

If you have the 5D Mark II (the latest version,) the raw converter in Photoshop CS3 does not support the format. If you have the earlier version of lthe 5D, download the latest raw converter update from Adobe (free}

If you have the Mark II you can do one of three things to continue using Photoshop:

1. Upgrade to CS4. The latest update for it's raw converter supports the 5D Mark II.

2. Download the Adobe DNG Converter when 5.2 version becomes available and convert your cr2 files to the DNG format which CS3 can read. In the past this has been available as a free download form Adobe, but it's not currently on their site.

3. Use the raw converter that came with your camera.

Raw Photos


"AW files are usually proprietary to the camera manufacturer and sometimes to the specific model of camera. That means, only the camera that takes the picture can understand the information collected on the camera sensors. That information is then translated by means of firmware (software) built into the camera and the usual result is a more user friendly format called JPEG."
From
Understanding RAW Format
Read also wikipedia :
Raw image format
In substance many software do not manage Raw format, this is normal. The newer photoshop CS3 can manage some Raw format , depending on the camera.

Photoshop 6 does not read Sony RAW format.
You need to export pictures from camera using jpeg, or to use a converter software if pictures are already on computer, see:

Raw file quality not as good as jpeg


RAW quality will always be at least as good as JPEG quality. The reason your JPEGs are coming out sharper is that the camera is actually doing post-processing on the RAW data, performing sharpening, white balance, contrast and brightness adjustment, etc., before saving the JPEG. The RAW data, as the name implies, is taken straight from the sensor, without the sharpening and other post-processing applied to it.
