The concept behind, or perhaps the need for, Develop mode can be a bit confusing when you’re first getting into processing your digital photos. I know that it wasn’t intuitive for me. But it’s a pretty sweet mode, so it’s worth taking the time to understand its value. So what’s this Develop mode I speak of all about?
When adjusting your images in Develop mode, the original file is never changed. The changes are saved in a separate file, and are applied each time you open the image. This allows for what we call “non-destructive” developing of your images. It is there to ensure that even if you go very far down a path altering an image, that even if you wind up with something you’re unhappy with, you always have the opportunity to start from scratch, as you possess an untouched original.
When you open a developed image in Develop mode, it displays the settings you previously left them at. This allows you to revisit the image at any time to adjust the previous settings.
So what does this mean for saving in Develop mode? When dealing with a RAW image, you make your changes, then click Done. The image’s develop setting are stored in the XMP file of the RAW and in the ACDSee database. If you’re talking encodable files, such as JPEGs, when you develop an image and press Done, the develop settings are stored in an XMP file, and the original and the XMP file are moved to the [Originals] folder. In Manage and View mode, the image with the changes applied is displayed. The develop settings are also stored in the ACDSee database. Basically, your original is safely preserved and stored with your changes, and your changes are added every time you look at it.
Ok, now that we’ve gone through the concept, let’s put it into practice. So take an image that you think could use some sprucing, and open it in Develop mode. Apply settings to achieve the look you want.
Now that you’ve got your image just as you want it, press Done. You’ll notice that your options are Save or Save As. Save As means that you save a version of your developed image with a new name or format and switch to the updated image. Maybe you’re generally inclined to play it safe in these cases and use the Save as option. But stay with me on this workflow first. So, press Save. *Cue dramatic music*
But, the next day, you come back to it and … what were you thinking? Your changes do not, er, stand the test of time, and your opinion on them has changed. Well now you’re in trouble, right? The original is gone.
Guess again! The original is preserved. In Manage mode, right-click the image. Go to Process | Restore to Original.
Et voilà Your original is back, no harm done.
In Edit mode, your original image is also preserved. However, the difference is that with Developed images, you can remove any of the changes you have made, regardless of the order that you added them. This allows you to avoid having to start from the beginning. In Edit mode, everything you do to an image is done on top of the results of the previous operation. If you added a series of 10 different edits, but wanted to remove the fifth edit, it would be necessary to start from scratch. But Develop mode bypasses the issue of an order of operations. You can even change the settings on individual selective adjustments, like brushes and gradients.
Furthermore, Edit mode is destructive, which means if you edit and save and edit and save and edit and save, each save degrades your image quality. But in Develop, your changes are all applied at the same time — you always start from the original.
What Else Makes Develop Mode Worthwhile?
Develop mode really makes a difference in the context of RAW photos. What is a RAW photo? A RAW image straight from the camera is undeveloped — it is merely sensor data. When you take the picture, the camera records all the light levels on its sensor and writes them to a file. It also writes in metadata from the camera, such as white balance settings. This is the RAW data.
When you shoot JPEGs, the camera takes that RAW sensor data and does develop processing on the image using the current camera settings, such as exposure and white balance, which produces the image that you see on the preview window or on your computer. Like a polaroid camera that produces the decent-looking image out directly from the camera, the develop processing is done in the camera and never needs to be done again.
Develop processing has to be done in order for a RAW file to be viewable. This processing occurs automatically using default settings, (based on the settings that your camera wrote into the RAW file, such as white balance), as ACDSee displays the image on the screen. Develop mode allows you to change and customize that automatically-applied develop processing to whatever you want it to be. So imagine you take a photo with the wrong white balance settings on your camera. If you’re shooting a JPEG, you can improve the image, but no matter what, you started out with a blueish image because of that wrong setting, and your ultimate image is never going to be perfect. However, if you shot the same image as a RAW, you can change the white balance settings in Develop mode and your results will be as though you went back in time and used the correct white balance settings from the beginning. You will get perfect results because you are working with the pre-white balance RAW sensor data.
Opening a RAW image in Edit mode does not do the same as Edit mode opens your RAW image with the RAW processing already applied.
It’s worth noting that if you alter an image in Edit mode first, and then take it into Develop mode, ACDSee will prompt that the edits will be lost. Develop mode needs to work with the original pixels, as opposed to pixels that have had develop processing added to them, and then editing.
Develop mode is also awesome for the advantage of develop presets.
