The first scheme:

Open this file, and then choose "Save As" directly, so a dialog box will appear asking whether to overwrite the original, agreeing, and then prompting you to modify the photo quality. You can reduce the photo "quality" to 8 or 6. If it is too low, you will obviously feel that the photo quality is declining. At this time, your photos should be controlled below1.5m.

The second plan:

Open this file, and then change the width of the picture to 2048 or 1280 in the picture modification option, and the height will automatically adapt. This will reduce the size of the photo. Then save, or adjust the quality to about 8, and overwrite the original document. The size can naturally be controlled within 1M, which will not affect the image quality too much.

I suggest adopting the second scheme.

Description:

I am a SLR user, using Nikon D300 and Canon 5D2. These SLR images are larger, and if I use large mode, it may reach 10M or more. So I shoot in small mode most of the time. I have also accumulated a large number of SLR photos over the years. In my opinion, if the photos are too big, if not for the competition, there is no need to keep them too big. More photos are used to record life and learn photography. If you need to keep some details, it is better to cut out the details you want to keep directly with ps. Too big a size will be your burden! And the width remains at 2048, which is enough to cope with the largest widescreen size at present. 1280 can also handle most computer screens. Therefore, it is suggested to use the second scheme to deal with photos, except that you want to participate in the competition or be selected into your personal selection (your favorite photos). You can save your hard disk.
