    Introduction and editing RAW file question.

    Hi.
    My name is Fleur and I am new to this forum.
    I'm hoping to enjoy other's photos and learn lots too.
    Atm I'm enjoying still photography of flowers as I'm an avid flower lover too.
    I'm actually wanting to have some photos enlarged so I have a technical question.
    I don't have a proper camera atm so use my Samsung S6 .
    It has 16 megapixels.
    When I take a photo in Pro mode 2 are saved to gallery in jpeg and RAW.
    The jpeg as you know is automatically edited so without further enhancing by myself it has 4.02 MB and a resolution of 5312 x 2988.
    The RAW image without enhancing has 30.89 MB and a resolution of 5328 x 3000.
    Now....when I move the raw to photoshop I fix up sharpness..brightness tone and contrast then move it back to gallery ..so it then has 18.33 MB and resolution of
    5312 x 2988.. but when I zoom in it has horrible noise.
    But when I zoom in on jpeg it doesn't?????
    So confusing..Im getting really upset and disillusioned.
    Really hope someone can help me.

    Welcome aboard.

    Sorry I can't help but hopefully someone will be along shortly who can. I'm not one for the technical stuff unfortunately

    Cheers Nate

    I do almost all my work with JPEGs. Iíve found that my late model cameras and phone cameras have more than enough dynamic range and resolution for me. Special shoots Iíll often take a combination but quite often Iíll end up using the jpegs.

    Hi..
    Thanks Closei..
    Im happy with jpegs too but apparently my printer says RAW is best for him but if I was to purchase a good high resolution camera ie canon EOS 5DS R which has huge MP ..then surely jpeg files would be fine for printing larger A2 prints .

    Welcome.
    I have not edited many photos from my phone, so I don't know a best way to do it.
    It became apparent to me though that they require a lighter touch compared to captures from larger sensors found in dedicated cameras.
    It could be you will get a better result not applying sharpening before saving to a compressed file and sharpen later if necessary.

    Examine the result magnified in photoshop after applying an editing procedure to see to the RAW file is taking it well.
    No doubt the stock edit the phone uses to output a jpeg will be finely tuned to stay within its sensors sweet spot.

    Phone images are remarkably good these days when the conditions are right. Cameras have more latitude to get an image taken in less than ideal conditions over the line.
    Cheers Doug

    With a 5DSR you could print hi res billboard size let alone A2

    Hi Doug.
    Thanks for your help.
    I have decided not to use phone camera for large prints.
    Will just have to buy a proper camera me thinks ��

    Re: Introduction and editing RAW file question.

    Welcome Fleur,

    If your after a new camera, and one that will take good macro images (close up), don't go past looking at one of the current high end compact cameras.

    These allow very close focusing and often closer than a standard lens on either a DSLR or mirroless.
    So unless you intend to start buying more lenses to get up close to smaller flowers, you might find it far cheaper (and smaller and easier to carry) than a DSLR.

    Many of the new compacts will have the option for RAW, your choice if you wish to use it or not.

    Another option to consider if you want to get up close, is lighting.
    Usually done with a ring flash.
    These are not cheap and designed to fit DSLR lenses.

    If you get a top end compact, they will have a hot shoe for a flash, so you can purchase a flash and adjust the light.
    Another string in your bow, and often used by pro flower photographers.

    You don't need to buy a top end DSLR to get good shots, many of the lower end models still have all the required tools to give you great shots.
    Knowledge of what your doing will trump buying expensive equipment %99 of the time.
    So take your time, ask lots of questions, and start saving (photography is a rabbit hole, there's no going back!!).

    It's hard to find a bad camera these days, I've been using mirrorless for several years now and they suit me fine. However I also use a bridge camera for convenience of not having to change lenses etc and am quite happy with the image quality from that as well.

    As Nigel said, high end compacts are excellent too and also convenient, so there's no end of choices for you.

    Re: Introduction and editing RAW file question.

    Jpeg is normally 8bit. that is 2 to the power of 8 = 256 bits per pixel.
    Raw is 2 to the power of 16 = 54000 bits of info....Maths?
    Some cameras that shoot in raw, process the file internally down to 14bit
    Working with raw you never loose the original file, but with Jpeg, as soon as you save it. The original file is gone! Unless saved under a different name.
    So, for me......NEVER EVER WORK IN JPEG!!!
    Noise in your photo?
    Hard to say. Not seen original file. Do not know your work flow. However, in 16 bit you will see a whole lot more information than Jpeg.
    If you work in 16 bit Jpeg, Say Adobe98, and then change profile to 8bit srgb...Then often the picture will look different and details will be softened.
    Welcome to the wonderful world of software and tearing your hair out.
    Kind regards;

    Re: Introduction and editing RAW file question.

    With the cost of ram so cheap now. Why work with inferior Jpegs?
    If it has been worked to death, why does it still come up with each new generation?

    Perhaps they just need to learn how to use their cameras!

    Still only new to this myself however my understanding is that part of the auto editing with jpeg is noise reduction. I don't use photoshop however I do know lightroom has a manual control for this.

    As does Photoshop. Can be applied to both RAW and JPEG images.
